BIOLOGICAL systems , *ANIMAL diseases , *ANIMAL health , *MULTIOMICS , *BIOLOGICAL fitness , *EPIGENOMICS - Abstract
The livestock industry faces significant challenges, with disease outbreaks being a particularly devastating issue. These diseases can disrupt the food supply chain and the livelihoods of those involved in the sector. To address this, there is a growing need to enhance the health and well‐being of livestock animals, ultimately improving their performance while minimizing their environmental impact. To tackle the considerable challenge posed by disease epidemics, multiomics approaches offer an excellent opportunity for scientists, breeders, and policymakers to gain a comprehensive understanding of animal biology, pathogens, and their genetic makeup. This understanding is crucial for enhancing the health of livestock animals. Multiomic approaches, including phenomics, genomics, epigenomics, metabolomics, proteomics, transcriptomics, microbiomics, and metaproteomics, are widely employed to assess and enhance animal health. High‐throughput phenotypic data collection allows for the measurement of various fitness traits, both discrete and continuous, which, when mathematically combined, define the overall health and resilience of animals, including their ability to withstand diseases. Omics methods are routinely used to identify genes involved in host‐pathogen interactions, assess fitness traits, and pinpoint animals with disease resistance. Genome‐wide association studies (GWAS) help identify the genetic factors associated with health status, heat stress tolerance, disease resistance, and other health‐related characteristics, including the estimation of breeding value. Furthermore, the interaction between hosts and pathogens, as observed through the assessment of host gut microbiota, plays a crucial role in shaping animal health and, consequently, their performance. Integrating and analyzing various heterogeneous datasets to gain deeper insights into biological systems is a challenging task that necessitates the use of innovative tools. Initiatives like MiBiOmics, which facilitate the visualization, analysis, integration, and exploration of multiomics data, are expected to improve prediction accuracy and identify robust biomarkers linked to animal health. In this review, we discuss the details of multiomics concerning the health and well‐being of livestock animals. [ABSTRACT FROM AUTHOR]

Background: Anthrax is a zoonotic disease caused by Bacillus anthracis that poses a significant threat to both human health and livestock. Effective preparedness and response to anthrax outbreak at the district level is essential to mitigate the devastating impact of the disease to humans and animals. The current diseaae surveillance in animals and humans uses two different infrastructure systems with online platform supported by established diagnostic facilities. The differences in surveillance systems affect timely outbreak response especially for zoonotic diseases like anthrax. We therefore aimed to assess the feasibility of implementing a simulation exercise for a potential anthrax outbreak in a local government setting and to raise the suspicion index of different district stakeholders for a potential anthrax outbreak in Namisindwa District, Uganda. Methods: We conducted a field-based simulation exercise and a health education intervention using quantitative data collection methods. The study participants mainly members of the District Taskforce (DTF) were purposively selected given their role(s) in disease surveillance and response at the sub-national level. We combined 26 variables (all dichotomized) assessing knowledge on anthrax and knowledge on appropriate outbreak response measures into an additive composite index. We then dichotomized overall score based on the 80% blooms cutoff i.e. we considered those scoring at least 80% to have high knowledge, otherwise low. We then assessed the factors associated with knowledge using binary logistic regression with time as a proxy for the intervention effect. Odds ratios (ORs) and 95% Confidence intervals (95%CI) have been reported. Results: The overall district readiness score was 35.0% (24/69) and was deficient in the following domains: coordination and resource mobilization (5/16), surveillance (5/11), laboratory capacity (3/10), case management (4/7), risk communications (4/12), and control measures (4/13). The overall community readiness score was 7 out of 32 (22.0%). We noted poor scores of readiness in all domains except for case management (2/2). The knowledge training did not have an effect on the overall readiness score, but improved specific domains such as control measures. Instead tertiary education was the only independent predictor of higher knowledge on anthrax and how to respond to it (OR = 1.57, 95% CI = 1.07–2.31). Training did not have a significant association with overall knowledge improvement but had an effect on several individual knowledge aspects. Conclusion: We found that the district's preparedness to respond to a potential anthrax outbreak was inadequate, especially in coordination and mobilisation, surveillance, case management, risk communication and control measures. The health education training intervention showed increased knowledge levels compared to the pre-test and post-test an indicator that the health education sessions could increase the index of suspicion. The low preparedness underscores the urgency to strengthen anthrax preparedness in the district and could have implications for other districts. We deduce that trainings of a similar nature conducted regularly and extensively would have better effects. This study's insights are valuable for improving anthrax readiness and safeguarding public and animal health in similar settings. [ABSTRACT FROM AUTHOR]

Nutrition may affect animal health due to the strong link between them. Also, diets improve the healing process in various disease states. Cancer is a disease, where the harmful consequences of tumors severely impair the body. The information regarding the evolution of this disease is extrapolated from human to animal because there are few specific studies regarding nutritional needs in animals with cancer. Thus, this paper aims to review the literature regarding the immunomodulatory effects of vitamins in mammal cancer. An adequate understanding of the metabolism and requirements of nutrients for mammals is essential to ensuring their optimal growth, development, and health, regardless of their food sources. According to these: 1) Some species are highly dependent on vitamin D from food, so special attention must be paid to this aspect. Calcitriol/VDR signaling can activate pro-apoptotic proteins and suppress antiapoptotic ones. 2) Nitric oxide (NO) production is modulated by vitamin E through inhibiting transcription nuclear factor kappa B (NF-kB) activation. 3) Thiamine supplementation could be responsible for the stimulation of tumor cell proliferation, survival, and resistance to chemotherapy. 4) Also, it was found that the treatment with NO-Cbl in dogs is a viable anti-cancer therapy that capitalizes on the tumor-specific properties of the vitamin B12 receptor. Therefore, diets should contain the appropriate class of compounds in adequate proportions. Also, the limitations of this paper are that some vitamins are intensively studied and at the same time regarding others, there is a lack of information, especially in animals. Therefore, some subsections are longer and more heavily debated than others. [ABSTRACT FROM AUTHOR]

AGRICULTURAL pollution , *ANIMAL health , *HYDROGEN fluoride , *FODDER crops , *POLLUTION management , *AGRICULTURAL extension work - Abstract
Purpose: Fluoride pollution in agricultural environments, particularly from industrial activities such as brick kilns, poses significant risks to crop yield and livestock health. This study investigates the impact of fluoride pollution on clover fodder, a critical feed source for livestock in the Peshawar region of Pakistan, and explores strategies to mitigate fluoride uptake using calcium amendments. Clover, specifically Persian clover (Trifolium resupinatum L.), is prone to accumulating high fluoride content, exacerbated by nearby brick kilns emitting hydrogen fluoride (HF). This accumulation poses a risk of fluorosis in livestock consuming the contaminated fodder. Methodology: A pot experiment was conducted to assess the effectiveness of adding calcium carbonate (CaCO3) at varying concentrations (0, 20, 40, and 60 µg/kg) to reduce fluoride uptake in clover. The study spanned three months, with plants harvested every four weeks to measure fluoride levels. Results: showed that increasing soil calcium significantly reduced fluoride content in clover leaves. At 60 µg/kg CaCO3, fluoride concentration decreased to 22 µg/kg from an initial 60 µg/kg at 0 µg/kg CaCO3. This reduction was consistent over 12 weeks, demonstrating the potential of calcium amendments to mitigate fluoride uptake. Additionally, a survey of farmers and agricultural extension workers in the affected areas revealed a lack of awareness and mitigation strategies for fluoride pollution. Conclusion: These findings highlight the need for policy interventions and educational programs to address fluoride pollution in agricultural systems. Implementing effective service economy strategies, such as providing subsidies for calcium amendments and conducting workshops on pollution management, can help reduce fluoride levels in fodder crops and safeguard livestock health. This study underscores the importance of collaborative efforts between government and local communities to develop sustainable solutions for managing fluoride pollution in agriculture.

- Abstract
The present study aimed to evaluate the potential hazardous effects of NO
3 − concentration in drinking water on health, feed intake, rumen fermentation and microbiota, and nitrogen excretion of Holstein heifers fed a high-concentrate diet for a sustainable water use. Twenty-four Holstein heifers were individually allocated and assigned to one of four treatments with increasing drinking water NO3 − concentration: CTR, without NO3 − ; LOW, with 44 mg NO3 − /L; MOD, with 110 mg NO3 − /L; and HIGH, with 220 mg NO3 − /L. The entire study lasted 168 days. Fortnightly water NO3 − concentration and daily feed and water intake were recorded. Blood parameters, rumen pH, volatile fatty acids, NO3 − and NO2 − concentration, microbiota, and apparent total tract digestibility were determined at the beginning and at the end of the study. Most of the analyzed parameters were similar among treatments. Denitrifying bacteria population, estimated as nosZ gene copies, were greater in HIGH animals than in CTR animals at the end of the study. In conclusion, drinking water NO3 − concentration up to 220 mg/L has no detrimental effect on health, feed intake, rumen fermentation, nor N excretion in dairy beef cattle for periods up to 168 days; moreover, denitrifying bacteria population increased, which are related with the neutralization of the greenhouse gas N2 O.

Urtica species is an angiosperm plant in the Urticaceae family. It serves as a traditional food and medicinal herb, possessing high nutritional value and various bioactive compounds, including polysaccharides, flavonoids, and polyphenolic compounds. In the realm of animal feeds, Urtica spp. can replace traditional protein feed sources and high-quality forage, thereby reducing feed costs. Moreover, Urtica spp. extract exhibits antioxidant and anti-inflammatory properties and boosts immune regulation. Hence, Urtica spp. plays a beneficial role in enhancing animal performance and improving their immune function. Recently, with the development of sustainable farming techniques, the demand for feed additives that prioritize safety, the absence of drug residues, and environmental friendliness have grown. Consequently, Urtica spp. and its extracts have received widespread attention in animal production. This article summarizes the biological functions of Urtica spp. and its application in animal husbandry while also outlining future prospects for its application. It will provide a scientific basis and reference point for the application of Urtica spp. in animal health and breeding. [ABSTRACT FROM AUTHOR]

CONSCIOUSNESS raising ,DRUG resistance in bacteria ,ENVIRONMENTAL health ,ANIMAL health ,ANTIMICROBIAL stewardship - Abstract
Antibiotic resistance (ABR) is a growing public health concern worldwide, and it is now regarded as a critical One Health issue. One Health's interconnected domains contribute to the emergence, evolution, and spread of antibiotic-resistant microorganisms on a local and global scale, which is a significant risk factor for global health. The persistence and spread of resistant microbial species, and the association of determinants at the humananimal-environment interface can alter microbial genomes, resulting in resistant superbugs in various niches. ABR is motivated by a well-established link between three domains: human, animal, and environmental health. As a result, addressing ABR through the One Health approach makes sense. Several countries have implemented national action plans based on the One Health approach to combat antibiotic-resistant microbes, following the Tripartite's Commitment Food and Agriculture Organization (FAO)-World Organization for Animal Health (OIE)-World Health Organization (WHO) guidelines. The ABR has been identified as a global health concern, and efforts are being made to mitigate this global health threat. To summarize, global interdisciplinary and unified approaches based on One Health principles are required to limit the ABR dissemination cycle, raise awareness and education about antibiotic use, and promote policy, advocacy, and antimicrobial stewardship.

Introduction: Livestock are central to pastoral livelihoods. A major constraint in pastoral production is livestock diseases, which is often exacerbated by inadequate surveillance systems. Reporting of disease outbreaks from pastoral communities to animal health workers is one of the challenges that affects effective and timely response to disease outbreaks. This study aimed to understand animal disease reporting and response in pastoral areas of Northern Kenya. Stakeholders, their roles, information flow among them and methods used for both livestock disease reporting and response and their strengths and challenges were identified. Methods: The study was carried out in Marsabit County, a pastoral county in Kenya. Pretested tools were used to guide data collection through Focus Group Discussions, Narrative and Key Informant Interviews with pastoralists, County government Animal Health Workers, agrovets and private animal health workers, Community Disease Reporters, Chiefs, County Public Health Officers and local Non-Governmental Organization staff. Net mapping was further used where participants drew links among the various stakeholders and assigned them perceived influence and power. Output from thematic analysis, notes taken during data collection and net maps were used to produce a network of stakeholders and their links using Gephi software. Centrality measures were generated and recorded. Perceived power and influence scores were used to produce a graph and the reasons for the scores documented. Methods used for livestock disease reporting and response were obtained from thematic analysis. Results: A network of 19 stakeholders with 67 links among them was identified. Major stakeholders were the Animal Owners/Pastoralists, Government Animal Health Workers, County Director of Veterinary Services, the Chief and radio based on network indices of Total degree and Betweenness Centrality, and also based on perceived scores of influence and power. Pastoralists had pivotal roles in both livestock disease reporting and response, Government Animal Health Workers (GAHWs) were mainly involved in disease surveillance and mass interventions including treatment and vaccinations. Non-state actors like NGOs and iNGOs collaborated and supported the County Government with resources to manage outbreaks. Various methods were used for reporting diseases, with use of mobile phones highly mentioned while for response to disease occurrences, the methods included trainings and treatment by both Government and Private AHWs and use of alternative veterinary practices by pastoralists. Various challenges constraining livestock disease response were highlighted, the most frequent challenges centered around low numbers and under resourcing of Animal Health Workers. Conclusion: These findings show that designing an efficient livestock disease surveillance system in pastoral areas requires recognition and utilization of all stakeholders and understanding of their roles. Gaps highlighted in disease response should be prioritized by the government and its development partners for improved animal health service delivery in pastoral areas. These inadequacies in livestock disease response have a direct effect on veterinary practice as mandated by the Government of Kenya Veterinary Surgeons and Para-professionals Act. The results are important for guiding policy formulation to support mitigation of disease impacts in similar areas with limited access to quality veterinary services. [ABSTRACT FROM AUTHOR]

Background: The encapsulation of metagenome-derived multi-enzymes presents a novel approach to improving poultry feed by enhancing nutrient availability and reducing anti-nutritional factors. By integrating and encapsulated enzymes such as carbohydrate-hydrolyzing enzymes, protease, lipase, and laccase into feed formulations, this method not only improves feed digestibility but also potentially contributes to animal health and productivity through antimicrobial properties. Results: This study investigates the encapsulation of metagenome-derived enzymes, including carbohydrate-hydrolyzing enzymes, protease, lipase, and laccase, using Arabic and Guar gums as encapsulating agents. The encapsulated multi-enzymes exhibited significant antimicrobial activity, achieving a 92.54% inhibition rate against Escherichia coli at a concentration of 6 U/mL. Fluorescence tracking with FITC-labeled enzymes confirmed efficient encapsulation and distribution, while physical characterization, including moisture content and solubility assessments, along with Atomic Force Microscopy (AFM) imaging, validated successful encapsulation. The encapsulated enzymes also effectively hydrolyzed poultry feed, leading to an increase in phenolic content and antioxidant activity, as confirmed by 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. Conclusions: The encapsulated multi-enzymes improved the overall feed quality by increasing reducing sugars and enhancing physical properties such as solubility and water-holding capacity. The encapsulated multi-enzymes improved the overall feed quality by increasing reducing sugars, antioxidant activity and enhancing physical properties such as solubility and water-holding capacity. Scanning Electron Microscopy (SEM) and Fourier-Transform Infrared Spectroscopy (FTIR) analyses confirmed the enzymatic breakdown of the feed structure. These results suggest that supplementing poultry feed with encapsulated multi-enzymes can enhance its physical, nutritional, and functional properties, leading to improved digestibility and overall feed quality.

TRAINING of veterinarians ,ECONOMIC impact ,DRUG resistance in microorganisms ,THEMATIC analysis ,ANIMAL health - Abstract
With the emergence of antimicrobial resistance (AMR), many countries are implementing restrictive regulations to reduce antimicrobial use (AMU) in animal production. Although these measures are effective at the national level, their implementation may generate challenges for producers and veterinarians. The objective of this study was to explore the barriers and facilitators of implementing a new regulation restricting the use of antimicrobials of very high importance for human health in the dairy production sector in the province of Québec, Canada. Individual interviews were conducted with fifteen veterinarians and twenty-seven dairy producers. Thematic analysis was performed based on the COM-B model of behavior change (capability-opportunity-motivation-behavior). Our results indicated that the lack of availability of alternative treatments, the long delays related to diagnostic tests and the fear of economic consequences were major barriers to the implementation of the regulation. A small number of producers also perceived that the regulation negatively impacted the health and wellbeing of their animals. Additionally, participants acknowledged the importance of early education and training to better understand the purpose of the regulation and increase its acceptability. Lastly, most participants reported that they had not only reduced their use of antimicrobials of very high importance for human health following the regulation, but they had also increased preventive practices on their farm. This study reveals that the implementation of restrictive regulations to reduce AMU in animal production can lead to multiple challenges in practice. Our results highlight the need for better communication and training of producers and veterinarians before and during the implementation of similar regulations in the future and underline the importance of measuring the direct and indirect impacts of those regulations on productivity and on animal health and wellbeing.

Mycotoxins are a major threat to animal and human health, as well as to the global feed supply chain. Among them, aflatoxins, fumonisins, zearalenone, T-2 toxins, deoxynivalenol, and Alternaria toxins are the most common mycotoxins found in animal feed, with genotoxic, cytotoxic, carcinogenic, and mutagenic effects that concern the animal industry. The chronic negative effects of mycotoxins on animal health and production and the negative economic impact on the livestock industry make it crucial to develop and implement solutions to mitigate mycotoxins. In this review, we summarize the current knowledge of the mycotoxicosis effect in livestock animals as a result of their contaminated diet. In addition, we discuss the potential of five promising phytogenics (curcumin, silymarin, grape pomace, olive pomace, and orange peel extracts) with demonstrated positive effects on animal performance and health, to present them as potential anti-mycotoxin solutions. We describe the composition and the main promising characteristics of these bioactive compounds that can exert beneficial effects on animal health and performance, and how these phytogenic feed additives can help to alleviate mycotoxins' deleterious effects.

Among the widespread trichothecene mycotoxins, T-2 toxin is considered the most toxic congener. In the present study, we utilized high-resolution magic-angle spinning nuclear magnetic resonance (HRMAS NMR), coupled to the zebrafish (Danio rerio) embryo model, as a toxicometabolomics approach to elucidate the cellular, molecular and biochemical pathways associated with T-2 toxicity. Aligned with previous studies in the zebrafish embryo model, exposure to T-2 toxin was lethal in the high parts-per-billion (ppb) range, with a median lethal concentration (LC50) of 105 ppb. Exposure to the toxins was, furthermore, associated with system-specific alterations in the production of reactive oxygen species (ROS), including decreased ROS production in the liver and increased ROS in the brain region, in the exposed embryos. Moreover, metabolic profiling based on HRMAS NMR revealed the modulation of numerous, interrelated metabolites, specifically including those associated with (1) phase I and II detoxification, and antioxidant pathways; (2) disruption of the phosphocholine lipids of cell membranes; (3) mitochondrial energy metabolism, including apparent disruption of the tricarboxylic acid (TCA) cycle, and the electron transport chain of oxidative phosphorylation, as well as "upstream" effects on carbohydrate, i.e., glucose metabolism; and (4) several compensatory catabolic pathways. Taken together, these observations enabled development of an integrated, system-level model of T-2 toxicity in relation to human and animal health. [ABSTRACT FROM AUTHOR]

Secondary metabolic products of molds, called mycotoxins, negatively affect animal health and production. They constitute a significant problem in veterinary and medical sciences, and their presence has been confirmed in feed all over the world. Applying appropriate agricultural practices and ensuring proper storage conditions significantly reduces the contamination of agricultural products with mycotoxins. However, this does not guarantee that raw materials are completely free from contamination. Many detoxification methods are currently used, but their insufficient effectiveness and negative impact on the quality of the raw material subjected to them significantly limits their usefulness. The positive results of eliminating mycotoxins from many products have been proven by the specific properties of microorganisms (bacteria, yeast, and fungi) and the enzymes they produce. Biological detoxification methods seem to offer the most promising opportunities to solve the problem of the presence of mycotoxins in animal food. This work, based on literature data, presents the health risks to farm animals consuming mycotoxins with feed and discusses the biological methods of their purification. [ABSTRACT FROM AUTHOR]

Simple Summary: Using bypass protein in ruminants' diets is crucial as it allows essential amino acids, like lysine, to escape rumen degradation and be absorbed in the intestine. This improves protein utilization and enhances growth, milk production, and overall animal health, leading to more efficient and sustainable livestock farming. This study explores the use of beeswax (BW) and carnauba wax (CW) lipid matrices to create bypass lysine (Lys) for ruminants, with tannins from Mimosa tenuiflora hay enhancing the protection of Lys. The research tested eight microencapsulated treatments with varying tannin levels (0%, 1%, 2%; 3%) using the fusion–emulsification technique. The results showed that adding tannins improved the microencapsulation yield and efficiency. Among the treatments, CWLys3% demonstrated the highest efficiency in retaining Lys and provided superior protection against rumen degradation. Our study demonstrated the efficiency of encapsulating the material (bypass protein) and making it available for the nutrition and growth of sheep. Future studies should determine what levels can be added to the diet and the consequences of using Lys bypass on the digestion and metabolism of sheep. Tannins are compounds present in forage plants that, in small quantities in the diet of ruminants, produce protein complexes that promote passage through the rumen and use in the intestine. This study tested the hypothesis that beeswax (BW) and carnauba wax (CW) lipid matrices are effective encapsulants for creating bypass lysine (Lys) for ruminants, with tannin extracted from the Mimosa tenuiflora hay source enhancing material protection. Microencapsulated systems were made using the fusion–emulsification technique with a 2:1 shell-to-core ratio and four tannin levels (0%, 1%, 2%; 3%). The following eight treatments were tested: BWLys0%, BWLys1%, BWLys2%, BWLys3%, CWLys0%, CWLys1%, CWLys2%, and CWLys3%. Tannin inclusion improved microencapsulation yield and efficiency. CWLys3% had the highest microencapsulation efficiency and retained Lys. Lysine in BW and CW matrices showed higher thermal stability than in its free form. Material retention was greater in BW than CW. Rumen pH and temperature remained unaffected, indicating that BW and CW as the shell and tannin as the adjuvant are efficient encapsulants for Lys bypass production. The formulation CWLys3% is recommended as it is more efficient in protecting the lysin amino acid from rumen degradation. [ABSTRACT FROM AUTHOR]

Simple Summary: Broiler meat is widely consumed around the globe. To fulfill consumer demand, broiler farmers are using antibiotic growth promoters for improved efficiency. However, these antibiotics have been banned in developed countries due to antimicrobial resistance. Therefore, plant supplements in the form of essential oils (EOs) have gained acceptability due to their excellent antibacterial properties. The next step is to encapsulate the EO for better delivery to target organs in broilers, which was investigated in vivo. The novelty of this study is to encapsulate volatile compounds of EOs in nanoemulsion (NE). This study has observed a positive effect of NE in terms of broiler growth performance, suggesting that cumin EO NE (CEONE) can be used as a substitute for the prophylactic administration of synthetic antibiotics. This research characterized and explored the effect of cumin essential oil nanoemulsion (CEONE) on broiler growth performance, serum biochemistry, hematological parameters, and cecal microbial count. Day-old (n = 96) broilers (Ross 308) were randomly assigned to six treatments with five replicates of three broilers each. The dietary treatments consisted of negative control (only basal diet), positive control (basal diet + 200 µL of enrofloxacin), 25 µL (basal diet + 25 µL of CEONE), 50 µL (basal diet + 50 µL of CEONE), 75 µL (basal diet + 75 µL of CEONE), and 100 µL (basal diet + 100 µL of CEONE). The broiler's body weight gain (BWG) after 42 days of treatment exhibited increased weight in the CEONE group (976.47 ± 11.82–1116.22 ± 29.04). The gain in weight was further evidenced by the beneficial microbe load (107 log) compared to the pathogenic strain. All the biochemical parameters were observed in the normal range, except for a higher level of HDL and a lower LDL value. This safety has been validated by pKCSM toxicity analysis showing a safe and highly tolerable dose of cuminaldehyde. In conclusion, this research observed the potential of CEONE as a multifunctional agent. It is a valuable candidate for further application in combating bacterial infections and enhancing animal health and growth. [ABSTRACT FROM AUTHOR]

Simple Summary: Technological advancements and growing interest in farm animal health have led to the development of various biometric devices. Among these, bolus-type biosensors have been extensively used to monitor adult cattle, but their application in calves remains limited. In this study, we evaluated a newly developed miniature bolus biosensor, equipped with a triaxial accelerometer and temperature sensor, to monitor physiological changes in beef and dairy calves. The biosensor was orally administered shortly after birth and monitored for retention and data accuracy. Our findings showed that most calves have successfully retained the biosensor, which provided valuable data on calf activity, body temperature, and responses to the stressful weaning period. Significant changes in these parameters indicate the possibility of using such biosensors for early health monitoring. While occasional regurgitation of the device was noted, this study highlights the potential of these biosensors for improving calf health management, though further validation is needed. In this study, a newly developed small wireless bolus biosensor, equipped with a triaxial accelerometer and temperature sensors, was applied to assess physiological changes in calves. The biosensor was orally implanted in calves, and its retention rate and location in the forestomach were examined. Data transmitted at 10 min intervals were analyzed to determine the characteristics of the calves at 10 and 100 days of age. Additionally, the daily averages of the vector magnitude (DV), changes in V over time (DV1), and reticular temperature (DRT) were analyzed during the experimental period. The biosensor was orally administered to twelve calves (six beef and six dairy) within 22 days of birth. Except for two regurgitated devices, the sensors transmitted data normally in a wireless manner for 15 weeks, recording physiological changes in the calves. The location of the biosensors was confirmed to be the reticulum. The analysis revealed that the V and V1 values were influenced by the physical characteristics of the biosensor's location. During weaning, DV and DV1 values first increased and then decreased compared to pre-weaning, while the DRT increased post-weaning and remained elevated. These findings suggest that these types of biosensors can be used for monitoring calf health; however, further research is needed to determine their ability to detect pathological states.

Simple Summary: Bovine respiratory disease (BRD) is one of the major threats to the health and well-being of young calves. The disease affects long-term animal performance and has economic implications for cattle producers. Preventative strategies such as metaphylaxis have been shown to reduce the severity of BRD and improve performance and overall health status. However, the use of antibiotics in this fashion continues to come under scrutiny due to its possible link to antimicrobial resistance. The objective of our study was to compare a metaphylaxis to a vaccination strategy in high-risk dairy and dairy beef cross-bred calves. The use of metaphylaxis for BRD was superior to the vaccination strategy in this study. Our study aimed to compare Bovine Respiratory Disease (BRD) morbidity, mortality, and growth in dairy and dairy beef cross-bred calves during the commingle period, 81–120 days of age, using two different BRD prevention strategies. The calves (n = 1799) were randomly assigned into groups: (1) Control (CON; received no vaccine or metaphylaxis); (2) Tulathromycin metaphylaxis (TUL; IncrexxaTM, Elanco Animal Health Inc., Greenfield, IN, USA); and (3) Mannheimia haemolytica vaccine (VACC; Nuplura® PH, Elanco Animal Health Inc., Greenfield, IN, USA). Calves were individually weighed three times during the study to estimate average daily gain (ADG). Deep nasopharyngeal swabs, thoracic ultrasonography, health scores, and treatment records were collected during the study. Ultrasound and health score results were not different across treatments. In this study, the TUL group had a lower cumulative BRD incidence than CON. The cumulative incidence and 95% CI of BRD during the commingle period, 81–120 days of age for CON, TUL, and VACC were 0.43 (0.38 to 0.47), 0.36 (0.38 to 0.40), and 0.39 (0.35 to 0.43), respectively. The ADG for CON, TUL, and VACC were 0.25 ± 0.15, 0.32 ± 0.15, and 0.17 ± 0.15 kg, respectively. There was no difference among the treatment groups for ADG. Management and environmental conditions were variable at this operation throughout the study period and likely impacted the calves. Earlier interventions may be needed when the BRD incidence is elevated in high-risk calves. [ABSTRACT FROM AUTHOR]

Simple Summary: The use of fermented agricultural by-products as novel feed additives to improve animal health and livestock production has attracted attention due to their enhanced nutritional values after fermentation. Blueberry pomace, rich in bioactive substances, has health benefits. This study investigated the effects of fermented blueberry pomace on intestinal health in late-phase laying hens. The findings indicated that dietary fermented blueberry pomace supplementation could improve small intestinal barrier function and modulate cecal microbiota in laying hens during the late laying period and thus could be a potential feed additive in poultry production. This study aimed to investigate the effects of fermented blueberry pomace (FBP) on the intestinal barrier function and cecal microbiome of aged laying hens. A total of 320 Yukou Jingfen No. 8 laying hens (345-day-old) were randomly divided into a control group, 0.25% FBP group, 0.5% FBP group, or 1.0% FBP group. The results showed that the villus height (VH) in the jejunum of the 0.25–0.5% FBP groups and villus surface area in the jejunum of the 0.25% FBP group were higher (p < 0.05), while 0.25% FBP supplementation displayed a higher (p = 0.070) VH in the ileum compared to the control group. Mucin-2 expression was upregulated (p < 0.05) in the jejunum of the 0.5% FBP group and the ileum of the 0.25–0.5% FBP groups. Compared to the control group, interleukin (IL)-4 and IL-13 expressions were upregulated (p < 0.05) in the 1.0% FBP group. Microbiota analysis revealed that Prevotella abundance in the cecum of the 0.5–1.0% FBP groups was higher (p < 0.05) than in the 0.25% FBP group. In addition, microbial function prediction analysis showed that cecal microbiota in the 0.25% FBP group were mainly enriched by alanine/aspartate/glutamate metabolism and methane metabolism. Moreover, Spearman's correlation analysis revealed the potential correlations between the abundance of the cecal microbiota and intestinal-barrier-function-related gene expressions, as well as the short-chain fatty acid content, of laying hens. In summary, dietary FBP supplementation enhanced intestinal barrier function by improving intestinal morphology, upregulating gene expressions related to barrier function, and altering the cecal microbiota of aged laying hens.

Since the pandemic in 2019, coronaviruses (CoVs) have been a great concern for public health burden. The fact that CoVs can infect all animals including domestic ones and livestock points to a future pandemic even though interaction between human and wildlife animals is restricted. Moreover, interspecies transmission abilities of CoVs by mutations make them drastically risky not only for humans but also for animal health. Recently, a new CoV outbreak in cats in Cyprus, the so‐called FCoV‐23, has been realized. In addition to worries over animal health, any possible transmission to humans is now controversial. However, there have been limited characterization studies on FCoV‐23. Thus, we aimed to assess the possible transmission of FCoV‐23 to humans using in silico prediction tools. Accordingly, we first checked the binding affinities of receptor binding domain (RBD) of FCoV‐23 against feline target protein and its human homolog. Next, we randomly and rationally created mutations on the RBD sequence and evaluated the binding affinities using protein docking tools. Our results underlined that multiple mutations at the same time were needed for increased binding affinity towards human target protein, demonstrating that the probability of transmission to humans was extremely low when mutation rates were regarded. Still, further molecular studies are required to comprehensively conclude the possible transmission risk. [ABSTRACT FROM AUTHOR]

The list of standard abbreviations for JDS is available at adsa.org/jds-abbreviations-24. Nonstandard abbreviations are available in the Notes. Nutritional strategies that improve an animal's resilience to various challenges may improve animal health and welfare. One such nutrient is niacin, which has reduced inflammation in mice, humans, and swine; however, niacin's anti-inflammatory effects have not been investigated in cattle. Our objective was to determine whether rumen-protected niacin (RPN) alters lactating dairy cows' inflammatory response to intramammary LPS challenges, whether RPN resulted in any carryover effects, and whether repeated LPS challenges result in signs of immune tolerance or innate immune training. Twenty healthy, late-lactation Holstein cows (232 ± 65 DIM; 39 ± 5.8 kg/d of milk) were enrolled in a randomized complete block experiment that lasted 70 d. Cows received 26 g/d of RPN or no top-dress (CON) for the first 42 d of the experiment. During the final milking of d 27 and 55, cows were challenged in their rear right (RR) mammary gland with 100 µg of LPS suspended in 5 mL of PBS. Milk yield, milk conductivity, and feed intake were measured daily. Milk composition was measured on d 14, 23, 24, 30, 37, 45, and 52. Blood samples were collected at 0, 8, 12, 24, 48, 72, 96, and 120 h after each LPS challenge, whereas RR quarter milk samples were collected at 0, 8, 16, 24, 48, 72, 96, 120, 144, and 168 h after each LPS challenge. Body temperature was measured continuously during each challenge with an intravaginal thermometer. Linear mixed models with repeated measures were used to analyze the results. Before LPS challenge, RPN did not affect feed intake or milk production, but it reduced SCS (1.24 ± 0.41 [SE] vs. 0.05 ± 0.45). After challenge, RPN did not affect feed intake, milk production, milk composition, SCS, body temperature, plasma glucose, or plasma insulin concentrations. Our results suggest RPN reduced peak plasma haptoglobin and lipopolysaccharide binding protein during the first LPS challenge. Plasma haptoglobin tended to be less after the second challenge for cows previously supplemented RPN, and lipopolysaccharide binding protein was similar for each treatment group after the second challenge. The second LPS challenge resulted in decreased plasma haptoglobin compared with the first LPS challenge, suggestive of tolerance, but it also induced a greater peak SCS than the first LPS challenge. Our results suggest that repeated LPS challenges promote a systemic tolerance but heightened local response to LPS-induced mastitis. Feeding RPN reduced SCS before challenge and reduced plasma acute phase proteins after challenge, suggesting that RPN may reduce systemic inflammation without altering the local inflammatory responses.

Globally, more than 50 countries have been affected by Monkey pox virus after COVID-19 has subsided. WHO declared "public health emergency of international concern" in year 2022 because of virus affecting 60,000 people in just one month that belonged to clade-IIb. Previously, it had been transmitted by body fluids, lesions and touching items, but fresh transmission is via sexual activity among bisexuals and man to man sex (MSM). New outbreaks reported compromised health status of confirmed cases with rectal pain, bleeding, tenesmus, pus or blood in stool, vomiting, proctitis and abdominal pain, which became alarming for entire world because of complications leading to bacterial skin infections, sepsis, encephalitis, hemorrhagic disease, blindness and pneumonia eventually. This virus has been further deteriorating unstable and unsustainable economy that requires dire attention. Strict preventive measures in terms of personal hygiene, pet and livestock health care, hospital contaminant disposal, good surveillance record, pre and post exposure vaccination, waste and water management could be only possible strategies to eliminate devastatingly dangerous M-pox outbreaks in this epic.

- Abstract
Ticks are obligate hematophagous ectoparasites that affect animals, and some of them transmit a wide range of pathogens including viruses, bacteria, and protozoa to both animals and humans. Several vaccines have shown immunogenicity and protective efficacy against ticks in animal models and definitive hosts. After several decades on anti-tick vaccine research, only a commercial vaccine based on a recombinant antigen is currently available. In this context, plants offer three decades of research and development on recombinant vaccine production to immunize hosts and as a delivery vehicle platform. Despite the experimental advances in plant-made vaccines to control several parasitosis and infectious diseases, no vaccine prototype has been developed against ticks. This review examines a panorama of ticks of veterinary importance, recombinant vaccine experimental developments, plant-made vaccine platforms, and perspectives on using this technology as well as the opportunities and limitations in the field of tick vaccine research.

Droughts negatively affect basins by reducing the river streamflow and increasing ion concentrations due to lower dilution. This study examines the impact of droughts in the Colorado River basin in Argentina. For this purpose, data were collected during the period from 2015 to 2021 at eight monitoring stations containing water from the river and drainage canals. The Standardized Precipitation Index (SPI) was used to analyze droughts from 1966 to 2020, and the Mann–Kendall test was used to evaluate the precipitation trends. In addition, water quality indices for human consumption (DWQI) and livestock (LWQI) were calculated by evaluating physicochemical parameters. The results show an intensification of drought since 2007, with an SPI of −1.5 in 2008, which affected the river streamflow regime and reduced the dilution capacity in the Casa de Piedra Dam. This reduction led to the deterioration of the water quality, with DWQI values indicating that 85% of the samples were not suitable for human consumption but were suitable for livestock consumption. In the drainage canals, most of the samples were of low quality for livestock consumption. The physicochemical analyses show that although some parameters (Na
+ , K+ , CO3 2− + HCO3 − , and Cl− ) were at acceptable levels, others (electrical conductivity, SO4 2− , and Ca2+ ) exceeded the WHO's limits, representing risks to human and livestock health. This study provides insights into how droughts and streamflow regulation affect the water quality in semiarid basins and highlights the broader applicability to other regions that present similar challenges under climate change scenarios.

This research aimed to study the effect of supplementation of Lactobacillus brevis and a combination of Lactobacillus brevis and Enterococus faecalis on growth performance, bacterial population and serum biochemical parameters in broilers. A total of 200 one-day-old chicks were obtained from a local hatchery. They were divided into four groups: group 1 served as a control, group 2 received commercial probiotics, group 3 received Lactobacillus brevis, and group 4 received the combination. The main parameters measured through 6 weeks were body weight, food intake, food conversion ratio (FCR), blood total protein, albumin and cholesterol. In addition to enumeration of bacteria from cloaca and caecum. The results showed a statistically significant increase in body weight (26%) for the group receiving the combined supplementation compared to the control. Similarly, there was a significant increase in FCR for this group compared to the control. The results also showed an increase in the Lactic acid bacteria (LAB) count in the caecum and a decrease in the total late count (TPC) and coliform count, showing the inhibitory effect of LAB. Also, there was a significant decrease in cholesterol and albumin level, while there was no difference between the different groups regarding protein level. The results showed that Lactobacillus brevis and Enterococus faecalis have a good potential to be used as probiotics in poultry. [ABSTRACT FROM AUTHOR]

The rationality in the use of veterinary drugs among sheep farmers has been a concern, particularly in remote areas of Lesotho. In this light, a descriptive survey was conducted where a cross-sectional design was employed to collect the data on the availability and rational use of veterinary drugs from a total of 102 sheep farmers. SPSS (Version 20.00) was used for data analysis, where the crosstabs within descriptive statistics were used to determine percentages while the significance was tested using both the Chi-square test and Fisher's exact test. Sheep farming in the study area is mostly dominated by adult men who are mostly married and have attained primary school leaving certificates, as reflected by 51.9% and 48.7% in rural and peri-urban villages, respectively. The use of commercial drugs for the control of diseases surpasses the use of medicinal plants, as demonstrated by 95.8% and 86.8% of responses in the rural and peri-urban villages, respectively. Moreover, the greater proportion of sheep farmers (83.3% and 89.1% in the rural and peri-urban, respectively) have not been trained on the use of veterinary drugs; however, it was observed that most of them diagnose and treat their animals on their own. The availability of veterinary services among sheep farming communities is very poor and mostly, farmers rely on farm feeds and hawkers as sources of drugs. The common method for dosage measurement is by guessing the animal's body weight. Most farmers are not aware of the withdrawal period following animal treatment as reflected by 78.2% and 63.8% of farmers in rural and peri-urban villages, respectively. Veterinary drugs are mostly stored at room temperature. In conclusion, the availability of veterinary drugs among farming communities is very poor and drugs are mostly irrationally used.

Prevalent etiological agents and treatment options are essential for diagnosing and managing fish diseases. Therefore, this study used standard microbiological procedures to enumerate and identify the total bacterial count in the water, skin, and gastrointestinal tract of 75 moribund cultured Clarias gariepinus from different culture facilities. Following that, the antibiotic susceptibility of the isolated bacteria to eight antibiotics was tested using the Kirby-Bauer disc diffusion method. Various clinical signs and pathological lesions were observed on the sampled moribund fish. Total bacterial count varied significantly (P < 0.05) regardless of the types of culture facilities. Bacteria species from eight different genera were present, comprising three Gram-positive bacteria, Bacillus subtilis, Streptococcus agalactiae, and Staphylococcus aureus, and five Gram-negative bacteria, Aeromonas hydrophila, Citrobacter freundii, Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica, in which Gram-negative bacteria (> 70%) were the most prevalent type of bacteria isolated. There was an association between the bacteria species isolated from the water and the different parts of the fish sampled regardless of the culture facilities. The antibiogram of the bacteria recovered revealed different sensitivity and resistance profiles. More than fifty percent of the Gram-negative bacteria were sensitive to ciprofloxacin, while the Gram-positive bacteria were susceptible to ciprofloxacin and gentamycin (> 40%). Amoxicillin, ampicillin oxytetracycline, and tetracycline resistance were high in the bacteria isolates. This study confirmed the presence of antibiotic-resistant pathogenic bacteria isolated with a multiple antimicrobial resistance (MAR) index of 0.63-0.75, indicating indiscriminate and irrational use of antibiotics.

Lumpy skin disease (LSD) is an infectious disease of cattle caused by lumpy skin disease virus (LSDV), which is a member of the Poxviridae family and genus Capripoxvirus. The illness is marked by mild to severe symptoms, including edema, fever, lymphadenitis, widespread skin nodules, and infrequently, death. In spite of its significance, little is now understood about the magnitude and predisposing factors in Tanzania. The aim of this study was to determine the seroprevalence of LSD in cattle within Kilolo district, and to identify key predisposing factors. A cross-sectional study was conducted in 17 villages within Kilolo district from February to March 2024 to estimate the seroprevalence of LSD in cattle. A total number of 276 serum samples was obtained from 65 cattle herds and a Double Antigen ELISA (ID Screen®) (IDVet, France) was used to screen for LSDV antibodies. Logistic regression analysis was employed to assess the risk factors for LSD seropositivity. The overall animal- and herd-level seroprevalence were 18.1% (95% CI: 13.98-23.14) and 44.6% (95% CI: 7.54-15.38), respectively. The highest individual animal level seroprevalence was documented in Irindi village 39.1% (95% CI: 5.36-12.24), followed by Masalali 38.5% (95% CI: 6.25-13.50), Ng'uruhe 37.5% (95% CI: 5.65-12.66), Irole 33% (95% CI: 1.5-6.10), and Utengule 26.5% (95% CI: 3.07-8.81) with significant differences (p=0.003). The seroprevalence of LSD varied significantly (P<0.001) among the three age groups, with adults >2 years having a higher seroprevalence (29.8%, 95%CI, 52.27-64.21) than yearlings aged 1-2 years (5. 6%, 95%CI, 9.31-17.60) and calves (0.0%, 95%CI, 23.36-34.35). Sex (Female/male, OR=2.0937, 95%CI, 1.4642-3.0248), age (Yearling/Adult, OR=0.1756, 95%CI, 0.0841-0.3730), village (OR=0.8970, 95%CI, 0.8349-0.9636) and herd size (Large/small, OR=1.9464, 95%CI, 1.1597-3.2669) were significant risk factors for LSDV seropositivity in Kilolo district. Raising awareness among livestock owners and veterinary staff about the disease and its risk factors, vaccination and vector control measures should be prioritized to minimize the transmission of the disease.

Nowadays, diseases are a major concern in fish production, particularly in gills, which play a crucial role in blood oxygenation, acid-base balance, osmoregulation, and waste elimination. Fungal infections, particularly Branchiomyces, cause respiratory problems in fish. This study aims to determine the causative agent causing high mortality in common carp, Cyprinus carpio, in the middle Euphrates in Iraq. One hundred infected fish were sampled for microbial, histological, and molecular examination. Gill tissue was examined as well for histological alterations, and DNA was isolated from Branchiomyces and amplified with universal primers. Microscopically identifying Branchiomyces spp. using lactophenol staining, non-separated hyphae and spores (5-9 m in size) at various stages inside the structures of gill tissue were present. Histopathological examination revealed hyperplasia of epithelial cells and infusion of gill filaments, while primary gill filaments displayed severe hemorrhage and edema. Hyphae of Branchiomyces have been detected between necrotic and edematous myofiber. The ITS PCR products of the fungal isolate were found to be positive at 540 bp molecular weight. Economic losses can occur as a result of fish infections caused by Branchiomyces. Histopathological lesions in gill tissue indicated the presence of Branchiomyces infection, which was confirmed by molecular and microscopical examination. [ABSTRACT FROM AUTHOR]

TROPONIN ,BIOMARKERS ,MYOCARDIAL injury ,MEDICAL care ,ANIMAL health - Abstract
A biomarker is defined as a detectable biomarker of a specific state and is often measured in urine, blood, milk, sweat, tear or soft tissue, either in physiological or pathological conditions. Of these commonly used biomarkers specifically for heart injury, there are cardiac troponin I (cTnI) and N-terminal pro-B-type natriuretic peptide. The cardiac troponin I is a sensitive biomarker formed by the injured cardiac cells and hence is used in humans for the early discovery of cardiac injury, and in parallel, it is used for prognostic purposes. Veterinary medicine widely uses cTnI as a marker for myocardial injury. In equines, cTnI was found to be a useful marker for the diagnosis of either primary or secondary myocardial injuries. It has also been used in newborn dogs to predict hypoxia and cardiac injury as a result of perinatal asphyxia. In neonatal calves with congenital heart anomalies, it was reported that the affected animals had a higher concentration of cTnI. In lambs with myocarditis, it was reported that significant levels of serum cTnI were detectable in diseased cases compared to healthy ones. This review article was written to emphasize the clinical significance of cTnI as a sensitive biomarker for cardiac injury in animals either in physiological or pathologic states. It has been concluded from several pathological and physiological studies that cTnI is a highly specific cardiac biomarker. It can detect myocardial injury due to primary cardiac disorders such as pericarditis, endocarditis and myocarditis. Also, it can predict cardiac injury in some non-cardiac-affected cases that can affect the heart, such as racing competitions, long road transportation, extensive training, difficult parturition, Downer syndrome, general anesthesia, infestation with external parasites such as ticks, calcium injection in extremely high doses, injection of cardiac glycosides, and use of the electroejaculation method to collect semen.

Egyptian consumers' demand and preference for sauces like mayonnaise have increased lately. The processing and packaging techniques of such products may safeguard the consumer from bacterial hazards, although mold and/or mycotoxins are still expected hazards in such products. Therefore, the current investigation is intended to determine the incidence of mold and aflatoxin B1 in commercial mayonnaise sold in Egyptian markets. A total of thirty mayonnaise samples were arbitrarily gathered from Cairo and Giza governorates in order to determine the presence of mold using cultivation techniques and AFB1 using a low-cost highrecovery fluorescence detector (FLD) in combination with an easy-to-use, highly specific and specially developed High-Pressure Liquid Chromatography (HPLC) assay that adhered to green chemistry principles. About 53.33% of the examined samples were positive for AFB1, while mold couldn't be detected in any of the examined samples. It was also discovered that 43.33% of AFB1 in total samples was below the maximum permitted threshold. Therefore, more attention is required from the authorities for continuous examination of such products that are present in the market for the incidence of chemical contamination with aflatoxin.

Poultry farming is crucial for the livelihoods of small-scale producers in the Northen Benin, yet the industry faces challenges from diseases like ND, which threaten both poultry health and economic stability. This study investigates the seroprevalence of Newcastle Disease Virus (NDV) among indigenous chickens and guinea fowl in the Atacora and Donga regions of Northern Benin, addressing a significant gap in regional poultry health data. A cross-sectional study was designed, sampling a total of 300 birds, including 191 indigenous chickens and 109 guinea fowl, from six districts. Systematic random sampling was employed to select smallholder farms, and blood samples were collected for Hemagglutination inhibition (HI) tests to detect NDV antibodies. Statistical analyses, including chisquare tests, determined associations and differences in seroprevalence between regions and species. Results revealed notable variations in NDV seroprevalence between the two regions. In Atacora, 59.22% of chickens tested positive for NDV antibodies, with 52.33% of non-vaccinated and 94.12% of vaccinated chickens showing positive results. In Donga, the overall seroprevalence was 46.59%, with 27.78% of non-vaccinated and 59.62% of vaccinated chickens testing positive. A chi-square test indicated a significant difference in NDV seroprevalence between the two regions for chickens (x2 = 12.901; P = 0.024). For guinea fowls, seroprevalence was 63.53% in Atacora and 62.50% in Donga, with no significant difference observed (x2 = 1.102; P = 0.954). This study provides the first serological data on NDV prevalence in northern Benin, highlighting the endemic nature of NDV and the critical epidemiological role of guinea fowls due to frequent exposure and field infections, especially in the Atacora region. It recommends enhancing vaccination coverage, improving biosecurity measures, and conducting further research to isolate and characterize virus strains to develop more effective control strategies.

This paper presents a potential strategy for the development of an antiviral agent against FMDV, specifically O Pan-Asia-2, A Iran 05 and SAT2/EGY/2012. Examining the potential use of interferon from the Bovine Ephemeral Fever Virus (BEFV) as a therapy is an intriguing approach. In order to test the cell toxicity and anti-FMDV in African green monkey kidney cell (Vero) and Baby Hamster Kidney Cell (BHK) cell lines up to serial dilutions of 10
-7 , BEFV was used to produce interferon in Vero and MDBK cell lines 12, 24, and 48 hours after cell infection. The in vitro findings showed that the cell safety and the ability of the prepared interferon to exhibit antiviral effects against various three FMDV serotypes, especially when administered shortly before or concurrently with the virus, are encouraging. The highest anti-FMDV effective dilution of the obtained interferon, either by Vero or MDBK cells, ranged from 10-3 to 10-4 . This suggests that the interferon may be able to activate cellular antiviral mechanisms and disrupt FMDV infection. The next critical step will be conducting further in vivo studies to evaluate the efficacy, safety, and potential side effects of the interferon-based treatment. This will provide important insights into virus-host interactions and the broader therapeutic potential of this approach. Some key areas for future research could include: expanding the testing of the interferon against additional FMDV serotypes to assess its breadth of coverage; Optimizing the administration parameters, such as timing, dose, and route, to maximize the antiviral effect, Investigating the specific mechanisms by which the interferon inhibits FMDV replication and spread, Evaluating the interferon's impact on disease progression and transmission in animal models, Assessing any potential negative effects or toxicity in the treated animals. The development of effective antivirals against FMDV is critical for controlling outbreaks and protecting livestock. This research represents a promising line of investigation that warrants further study. [ABSTRACT FROM AUTHOR]- Published

MARINE pollution ,CORALS ,ANIMAL diseases ,ANIMAL health ,MEDICAL care - Abstract
Hard corals are precious marine creatures that comprise a complex form of symbiosis between symbiont algae and coral holobiont. For decades, corals have been challenged by disastrous events of climatic and anthropogenic etiologies. Such complex interactions have resulted in devastating disease episodes among coral populations worldwide. There is a scarcity of information about diseases of hard corals in the Gulf of Aqaba, Red Sea, Egypt. Therefore, the current study aims to investigate various diseases of hard corals in this pristine habitat within the Red Sea. Whitening and dark green dots were the most noticeable morphopathology among hard coral samples collected from Gulf of Aqaba. Some human-based pathogens, such as Rothia kristinae, Cupriavidus pauculus, and Delftia acidovorans, were isolated from some of the examined coral tissues, while the Burkholderia cepacia group was isolated from the nearby sediment. The final identities of the above-mentioned bacterial isolates have been molecularly confirmed using 16S RNA sequence analysis. Pathologically, diseased corals have been observed with changes such as some forms of tissue losses, degenerative changes, and eosinophilic granular amoebocytes/agranular cells infiltration. The frequent detection of some microbial pathogens of human origin could suggest deleterious forms of environmental pollution of anthropogenic origin. Ultimately, the entire existence of hard coral populations is mostly threatened by swiftly erupting climatic changes as well as environmental aquatic pollution. Thus, the current study concludes the real need for extensive ecological, biological, pathological, and immunological studies to determine the eminent threats and propose possible control means for better/sustainable hard coral populations.

INFECTIOUS bursal disease virus ,ANIMAL health ,CHICKENS ,MEDICAL care ,IMMUNIZATION - Abstract
Gumboro, or infectious bursal disease (IBD), represents a significant threat to poultry worldwide due to its genetic and pathogenic variations. Viruses can mutate and produce new variants, which can have an impact on the epidemiological situation. The study will determine and assess the genetics, protein sequence, and pathogenicity of IBDV present in broiler flocks in different locations within Ismalia and Dakahlia Governorates, Egypt, in 2022. A total of 150 bursa samples were collected from 15 broiler flocks exhibiting symptoms indicative of IBDV infection. The VP2 (viral protein2) gene was partially detected and then subjected to complete gene sequencing in order to summarize the key genetic mutations found and histopathological examination. The results demonstrated that 12 out of 15 farms were infected with IBDV. Genetic analysis revealed that 10 of the 12 identified strains belonged to genogroup 3, which was similar to previous Egyptian strains. The remaining two strains were of genus 1. The VP2 gene's hypervariable region displayed amino acid alterations at several positions. Classic IBDV strains (genogroup 2) showed similar amino acid profiles. Amino acid alterations were identified in the VP2 gene, indicating that classic IBDV strains may cause damage to the bursa of Fabricius, leading to immunosuppression. In Egypt, vvIBDV (very virulent infectious bursal disease virus) strains have led to recurring outbreaks and high chick mortality rates. These findings are anticipated to contribute to the latest features of IBDV in the examined regions. Therefore, it is recommended that IBDV immunization programs in Egypt, where live attenuated virus vaccinations are common, be reevaluated. It is also recommended that the evaluation of clinical signs in broiler chicken flocks over time be monitored for diagnosis. [ABSTRACT FROM AUTHOR]

The weight of livestock is a crucial metric for evaluating management efficacy, informing policy decisions, and determining the market value of animals. In certain scenarios, conventional methods such as physical weighing and measurement calculations can prove challenging, including the absence of livestock health records or weighing equipment. This research aims to develop a predictive model for estimating the live weight of cattle through visual assessments and metadata, including age and pixel count, utilizing a combination of convolutional neural network (CNN) and artificial neural network (ANN) methodologies. A total of 223 data were obtained from a local farm before augmentation. The model's predictive capability was successfully demonstrated, with its performance quantified by an average mean absolute percentage error (MAPE) of 10% on test data. This study demonstrates that through the combination of CNN and ANN, as well as optimal parameter tuning, efficient prediction of cattle weight can be achieved. [ABSTRACT FROM AUTHOR]

Q fever is a disease caused by Coxiella burnetii, which can cause serious illness in humans and abortions in goats. A Q fever outbreak among an unvaccinated goat herd led to a 65% loss of the kid crop in spring 2018. To assess the impact of the outbreak on the herd and environment, longitudinal surveillance of the ranch was conducted across three samplings in September 2018, April 2019, and May 2022. Antibodies against C. burnetii were monitored by an indirect immunofluorescence assay. Shedding was monitored through analysis of vaginal/fecal swabs and milk. Environmental swabs and bulk soil were collected from various locations around the ranch. Animal and environmental samples were analyzed for C. burnetii DNA by PCR. Herd-level seroprevalence decreased from 89% in 2018 to 84.3% in 2019, and 64.5% in 2022. Overall herd shedding was 14.4% in 2018, 7.4% in 2019, and 6.7% in 2022. The percentage of C. burnetii-positive environmental samples was 83.7% in 2018, 51.7% in 2019, and 28.6% in 2022. Serological evidence suggests that new infections were occurring in the herd 4 years post-abortion storm. This study demonstrates the presence of C. burnetii shedding and environmental contamination in a goat operation at least four kidding seasons after an outbreak. A better understanding of management practices that can improve outcomes for infected herds, particularly in areas without access to vaccines against C. burnetii, is needed to better protect operators and the public.

This paper is derived from a presentation given by the first author at the 2024 Symposium for the Calvin Schwabe Award, presented to Dr. Jan Sargeant for Lifetime Achievement in Veterinary Epidemiology and Preventive Medicine. Researchers must work toward ensuring validity throughout the research process, but we also should ensure that our resulting outcomes are specified to appropriately inform and enable decision-making by the end-users. Given the scope and diversity of topics addressed by veterinary researchers, the potential beneficiaries or stakeholders of our research also varies. Stakeholders or endusers may include veterinary practitioners, other researchers, livestock owners, "pet parents," government officials, corporate entities, or the general public in the case of public health or food security and safety issues. Current research in animal agriculture provides an opportunity to consider research outcomes in a sustainability framework which concurrently values social, economic, and environment impacts of animal health and management decisions. In companion animals, contemporary issues of affordability and access to care, quality of life, or compliance effects on efficacy, also extend the spectrum of relevant research outcomes. In these cases, traditional measures of animal health, such as morbidity, mortality, or weight gain, may not be the most relevant for the end-users. Furthermore, if studies are not designed and analyzed with well-defined primary outcomes that are informed by stakeholders' values, but rather post-hoc considerations of these values are made based on indirect or surrogate measures, there is the potential to incorporate error and bias into our conclusions and the end-users' decision-making processes.

GUT microbiome ,ANIMAL health ,ENERGY metabolism ,HIBERNATION ,MAMMALS - Abstract
Hibernation, an evolved survival trait among animals, enables them to endure frigid temperatures and food scarcity during the winter months, and it is a widespread phenomenon observed in mammals. The gut microbiota, a crucial component of animal nutrition and health, exhibits particularly dynamic interactions in hibernating mammals. This manuscript comprehensively evaluates the impacts of fasting, hypothermia, and hypometabolism on the gut microbiota of hibernating mammals. It suggests that alterations in the gut microbiota may contribute significantly to the maintenance of energy metabolism and intestinal immune function during hibernation, mediated by their metabolites. By delving into these intricacies, we can gain a deeper understanding of how hibernating mammals adapt to their environments and the consequences of dietary modifications on the symbiotic relationship between the gut microbiota and the host. Additionally, this knowledge can inform our comprehension of the protective mechanisms underlying long-term fasting in non-hibernating species, including humans, providing valuable insights into nutritional strategies and health maintenance.

Background: Tick-borne pathogens are understudied among domestic animals in sub-Saharan Africa but represent significant threats to the health of domestic animals and humans. Specifically, additional data are needed on tick-borne pathogens in Chad, Africa. Surveillance was conducted among domestic dogs in Chad for selected tick-borne pathogens to measure (1) the prevalence of antibodies against Anaplasma spp., Borrelia burgdorferi, and Ehrlichia spp.; (2) the prevalence of infections caused by Hepatozoon spp., Ehrlichia canis, Anaplasma platys, and Babesia spp.; and (3) associations of pathogens with demographic, spatial, and temporal factors. Blood samples were collected from domestic dogs at three time points (May 2019, November 2019, June 2020) across 23 villages in southern Chad. Results: Of the 428 dogs tested with the IDEXX SNAP 4Dx test in May 2019, 86% (n = 370, 95% CI = 83–90%) were positive for antibodies to Ehrlichia spp., 21% (n = 88, 95% CI = 17–25%) were positive for antibodies to Anaplasma spp., and 0.7% (n = 3, 95% CI = 0.1–2%) were positive for antibodies to Borrelia burgdorferi. Four different pathogens were detected via PCR. Hepatozoon spp. were most commonly detected (67.2–93.4%, depending on the time point of sampling), followed by E. canis (7.0-27.8%), A. platys (10.1–22.0%), and Babesia vogeli (0.4–1.9%). Dogs were coinfected with up to three pathogens at a single time point, and coinfections were most common in May 2019 compared to November 2019 and May 2020. Conclusions: Overall, this study provides new data about the epidemiology of tick-borne pathogens in domestic dogs in Chad, with potential implications for dog and human health.

There are many pollutants present in wastewater that require urgent remediation. Methylene blue (MB) has become the most undesirable pollutant. Various industries such as petroleum, pharmaceuticals, textiles and households have been responsible for releasing MB into the environment. Its toxicity and acute health implications for animals and humans have suggested several technological applications for its removal. Biological methods using plant‐based wastes have been identified to be the most effective material for removing MB and other dye pollutants. Previous research studies have employed biological adsorbents to eliminate MB and were reviewed. The purpose of the study was to determine the removal efficiency gap of MB using biological wastes. In this present review, various biological wastes and their functionalization were explored. The study proved that chemically modified bioadsorbents were favourable in removing MB. Its ability to produce secondary pollutants from chemical agents has made it undesirable. Several factors such as pH, dosage of catalyst, contact time and temperature have also been reviewed to influence biosorption. The best data representations to describe the biosorption of MB were the Langmuir and pseudo‐second‐order models. [ABSTRACT FROM AUTHOR]

Simple Summary: Infrared thermography is a rapid, contactless technology that can provide real-time temperature measurements, with various applications in livestock science within the framework of precision livestock farming. The aim of the current review paper is to present the updated state of knowledge regarding the detection of mastitis in dairy ruminants using infrared thermography. Therefore, it summarizes the technological advancements, the diagnostic capacity, and the operational and analytical challenges of the method when applied under real-world conditions as a diagnostic tool for mastitis, while factors associated with the performance of the method are critically described and discussed to justify recognized strengths, weaknesses, opportunities, and challenges of the method. Among the health issues of major concern in dairy ruminants, mastitis stands out as being associated with considerable losses in productivity and compromised animal health and welfare. Currently, the available methods for the early detection of mastitis are either inaccurate, requiring further validation, or expensive and labor intensive. Moreover, most of them cannot be applied at the point of care. Infrared thermography (IRT) is a rapid, non-invasive technology that can be used in situ to measure udder temperature and identify variations and inconsistencies thereof, serving as a benchmarking tool for the assessment of udders' physiological and/or health status. Despite the numerous applications in livestock farming, IRT is still underexploited due to the lack of standardized operation procedures and significant gaps regarding the optimum settings of the thermal cameras, which are currently exploited on a case-specific basis. Therefore, the objective of this review paper was twofold: first, to provide the state of knowledge on the applications of IRT for the assessment of udder health status in dairy ruminants, and second, to summarize and discuss the major strengths and weaknesses of IRT application at the point of care, as well as future challenges and opportunities of its extensive adoption for the diagnosis of udder health status and control of mastitis at the animal and herd levels.

Mineral micronutrient deficiencies are widespread in global food systems and can affect plant growth, crop quality, and human and livestock health. The mapping of soils and soil properties linked to micronutrient supply in food systems is now enabling us to better understand the linkages between soil health and function and its relationship with food quality and human health. Zinc (Zn) deficiencies in Indian soils are of particular concern in the context of crop yields and food quality. This current review aims to understand the data landscapes on soil Zn and related soil properties in India, with a particular focus on three states: Uttar Pradesh (UP), Bihar, and Odisha. The scope of the review is to identify and describe data sets from national and state-wide programmes and research experiments in which soil Zn has been reported, which could be used to provide a framework for integrated surveys and would combine wider agriculture, food systems, nutrition, and public health sectors. The largest data set on soil Zn was collected under a soil health management (SHM) programme, during which the Indian government analysed more than 30 million soil samples for Zn concentration (mg/kg) from 2015 to 2019. This study showed that 39% of Indian soils are considered Zn deficient for crop production (i.e., based on a threshold of <0.6 mg/kg); soil Zn deficiency varied from 2% to 67% across different Indian states. From this survey, soil Zn deficiency was 29%, 67%, and 48% in UP, Bihar, and Odisha, respectively. Individual data points are available for re-use at the Government of India soil health card website (https://www.soilhealth.dac.gov.in/). In addition, the All India Coordinated Research Project on Micro and Secondary Nutrients and Pollutant Elements in Soils and Plants (AICRP-MSPE) programme under the Indian Council of Agricultural Research (ICAR) analysed >240,000 soil samples from 2012 to 2018 from 28 states of India and reported ~38% soil Zn deficiency in the Indian soils. There is no programme in India that currently maps micronutrients in soil and crops together using "GeoNutrition" approaches recently reported in two countries in Africa, Ethiopia, and Malawi. Future co-ordinated soil and crop micronutrient mapping in India can help us to understand better the movement of Zn (and other micronutrients) in food systems and to inform strategies to improve the Zn status in the soil, e.g., the use of Zn fertilisers for yield and agronomic biofortification, and in the edible tissues of crops, e.g., through genetic biofortification.

Milk is an ideal environment for the growth of microorganisms, especially psychrotrophic bacteria, which can survive under cold conditions and produce heat-resistant enzymes. Psychrotrophic bacteria create the great problem of spoiling milk quality and safety. Several ways that milk might get contaminated by psychrotrophic bacteria include animal health, cowshed hygiene, water quality, feeding strategy, as well as milk collection, processing, etc. Maintaining the quality of raw milk is critically essential in dairy processing, and the dairy sector is still affected by the premature milk deterioration of market-processed products. This review focused on the recent detection and control strategies of psychrotrophic bacteria and emphasizes the significance of advanced sensing methods for early detection. It highlights the ongoing challenges in the dairy industry caused by these microorganisms and discusses future perspectives in enhancing milk quality through innovative rapid detection methods and stringent processing controls. This review advocates for a shift towards more sophisticated on-farm detection technologies and improved control practices to prevent spoilage and economic losses in the dairy sector.

The exponential increase in global population continues to present an ongoing challenge for livestock producers worldwide to consistently provide a safe, highquality, and affordable source of protein for consumers. In the last 50 years, the poultry industry has spearheaded this effort thanks to focused genetic and genomic selection for feed-efficient, high-yielding broilers. However, such intense selection for productive traits, along with conventional industry farming practices, has also presented the industry with a myriad of serious issues that negatively impacted animal health, welfare, and productivity-such as woody breast and virulent diseases commonly associated with poultry farming. Bacterial chondronecrosis with osteomyelitis (BCO) lameness is one such issue, having rapidly become a key issue affecting the poultry industry with serious impacts on broiler welfare, meat quality, production, food safety, and economic losses since its discovery in 1972. This review focuses on hallmark clinical symptoms, diagnosis, etiology, and impact of BCO lameness on key issues facing the poultry industry. [ABSTRACT FROM AUTHOR]

Background: Swine dysentery, caused by Brachyspira hyodysenteriae, is a severe pig disease. Resistance to tylosins is common and resistance to tiamulin has been reported since the 1990s. Still, dysentery is not notifiable to authorities. The disease therefore escapes control from an overall population perspective. In Sweden, a program that aimed to control dysentery at national level was initiated in 2020, mainly due to the unexpected diagnosis of tiamulin resistant Brachyspira hyodysenteriae in 2016. Results: Through joint efforts of a network including farmers, government, animal health organisations and abattoirs it was concluded that outbreaks of dysentery had taken place in 25 herds between 2016 and 2019. By 1 January 2020, nine of these herds were still not declared free from the disease. From that date, the network decided that Brachyspira hyodysenteriae was to be cultured whenever dysentery could be suspected. Thus, 148, 157 and 124 herds were scrutinised for Brachyspira hyodysenteriae in 2020, 2021 and 2022, respectively, whereof five, three and two new herds were confirmed positive. By 31 December 2022, four herds were judged as impossible to sanitise. However, they posed no problem since they were identified by the network, pigs to and from these enterprises could be transported without jeopardising other herds. When Brachyspira hyodysenteriae was diagnosed in fattening herds purchasing growers, Brachyspira hyodysenteriae could not be detected in the delivering herds. That result, together with other observations, indicated that Brachyspira hyodysenteriae ought to be regarded as ubiquitous, although at a low level in healthy pigs. Conclusions: Eradication of dysentery contributed to substantial welfare and financial improvements in affected herds. Dysentery was controlled successfully at national level through the united efforts from competing stake holders, such as different abattoirs and animal health organisations. However, as Brachyspira hyodysenteriae was assumed to be ubiquitous, although at a low level in healthy pigs, the duration of the successful control of dysentery was concluded to only be transient. Without permanent monitoring for Brachyspira hyodysenteriae, the knowledge of the national status will rapidly decline to the level prior to the initiation of the control program.

ANIMAL health surveillance ,AFRICAN swine fever ,ANIMAL health ,Q fever ,ENVIRONMENTAL health - Abstract
The French National Animal Health Surveillance Platform (NAHSP) was created in 2011. This network of animal health stakeholders was set up to improve surveillance efficiency for all health risks that threaten animal health, as well as zoonoses affecting human health. The NAHSP steering committee decides on the strategies and program of activities. It is composed of 11 institutions from both public and private sectors (policy-makers, scientific institutions, and representatives of farmers, veterinarians, hunters, and laboratories). A coordination teamguarantees the implementation of the programand facilitates the activities of different working groups (WGs). Each WG is composed of technical experts with scientific, legal, and field knowledge from the sectors of animal health (livestock, companion animals, and wildlife), human health, and environmental health. Some WGs focus on a specific disease or health indicator, such as African swine fever or cattle mortality, while others cover cross-cutting topics, such as epidemic intelligence (EI), or specialize in aiding epidemiological investigations, such as the Q fever WG. The NAHSP stands out for its innovative approach because it is based on the concepts of consensus-building among participants, fostering collaboration, and embracing interdisciplinarity. Each proposal designed to improve surveillance is jointly developed by all the stakeholders involved, thereby ensuring its sustainability and acceptability among stakeholders. This process also has added value for decision-makers. As a pioneer platform, the NAHSP inspired the creation of two additional national surveillance platforms in 2018, one for plant health and the other for food chain safety. Both are organized in the same way as the NAHSP, which created a framework to place the emphasis on a One Health approach. For instance, four WGs are common to the three national surveillance platforms. This article aims to present this innovative approach to improve surveillance efficiency that could be of interest to other European countries or that could be rolled out at the European level.

There is an increasing need for robust wildlife health programs that provide surveillance and management for diseases in wildlife and wild aquatic populations to manage associated risks. This paper illustrates the value of a systematic method to enhancing wildlife health programs. The U.S. Geological Survey and Mahidol University, Faculty of Veterinary Science, Thailand National Wildlife Health Center formally twinned under the auspices of the World Organisation for Animal Health to enhance wildlife health capacity in Thailand and the Southeast Asia Region. We used a system-wide approach to holistically and interdependently enhance capacity. The project commenced with a wildlife health program needs assessment, and capacity enhancement focused on strengthening the general wildlife health surveillance network and improving wildlife health information management. Activities included partner surveys, interactive and didactic workshops, and individual personnel training. Topics included development of wildlife health information management systems, analysis of the current surveillance network, development of a Theory of Change for a strengthened surveillance network, planning workshops to create a wildlife health network, training on wildlife disease outbreak investigation and field sample collection, leading networks, and individual training on bioinformatics and laboratory techniques. Engagement of stakeholders at all levels, continuous communication throughout the project, use of both strategic planning tools and pedagogical methods, and using iterative and adaptive approaches, were key factors to the success of this project.
