Abstract

Background: Mastitis is an inflammatory disease of the mammary gland, mostly associated with bacterial infections. It is responsible for great economic losses due to decreased milk yield, discarded milk, milk composition alterations and treatment costs, besides it impairs the animal health and welfare. The rumination time is an important behavioral marker and its assessment can be used as an early diagnosis tool, which can improve cure rate. Therefore, the aim of the present study was to evaluate the sensitivity of behavior monitoring system collars in the diagnosis of mastitis and the average rumination time (RT) of Holstein cows during the healthy period and affected by the disease. Materials, Methods & Results: The study was conducted on a commercial property located in the municipality of Rio Grande, Rio Grande do Sul, Brazil. The RT data from 39 multiparous Holstein cows with an average milk yield of 38.4 L/ day was collected. RT monitoring was performed using C-Tech1 collars combined with CowMed® software, which assess behavior data from the animals and emits warning signals when it finds abnormalities in any parameter. In order to verify whether the animals were determined correlated with diseases, the sensitivity of the data was evaluated, when the system had given the alert to animals considered ill, they underwent to a further clinical evaluation performed by a veterinarian to confirm the diagnosis. From the diagnosis, the cows were divided into subclinical mastitis (SM) and clinical mastitis (CM) groups. SM was detected by the California Mastitis Test (CMT) and cows that were graded 1 (++), 2 (++) or 3 (+++) without the presence of any other clinical sign were assigned to the SM group. CM was assessed by observation of abnormalities in milk such as changes in color and consistency, as well as the presence of lumps, clots or blood; and clinical examination of the udder was performed for detection of hot, hard, swollen or painful quarters. Thereafter, variations in the mean RT between the healthy (15 days) and sick periods (days when there was an alert) were evaluated. For the identification of the etiological agents involved in the cases of CM, microbiological cultures were performed on Accumast® plates with milk samples, which were incubated at a temperature of 37°C and the diagnosis of the pathogens were performed after16 hours of incubation. During the study, 57 cases of mastitis were observed, 42 were SM and 15 were CM. The sensitivity of the system, which is the ability to detect positive cases of the disease, was 73.8% for SM and 73.3% for MC. The RT of the animals were compared individually during the healthy period with the sick period and it was observed that SM reduced the RT by 5.33% whereas MC reduced the RT by 14.9%. Discussion: The maximum RT values were lower during the disease period in relation to the period in which the animals were healthy, for both SM and CM, which is due to the fact that the disease is responsible for causing inappetence in animals, among other clinical signs, therefore, reducing feed consumption. The lowest variation in RT, between the healthy and sick period, was observed in cases of SM, which was already expected, since the clinical form tends to cause more discomfort to the animals. As for the main etiological agents involved in the clinical condition, Streptococcus agalactiae and S. uberis were detected. In view of the above, the evaluation of the mean RT of multiparous dairy cows was efficient in the predictive diagnosis of SM and CM up to two days before the onset of the disease. In addition, the variability of this result demonstrated that animals with subclinical cases presented less fluctuation in RT. [ABSTRACT FROM AUTHOR]

Abstract

O objetivo deste trabalho foi validar um protocolo para a indução de acidose ruminal subaguda (SARA) (Experimento 1) e testar a eficácia do probiótico Saccharomyces cerevisiae ou monensina na prevenção da queda do pH do fluido ruminal em ovinos (Experimento 2). No Experimento 1, seis ovelhas foram mantidas em jejum por dois dias e, em seguida, alimentadas basicamente com concentrado durante quatro dias. Nesse protocolo as ovelhas mantiveram o pH do fluido ruminal abaixo de 6,0 por 75 horas consecutivas. No Experimento 2, 18 ovelhas foram distribuídas em três grupos: controle (GC, n = 6), monensina (GM, n = 6) e o grupo probiótico (GP, n = 6). SARA foi induzida de acordo com o Experimento 1. PG apresentaram valores de pH mais baixos (5,7 ± 0,1) do que o GC (6,0 ± 0,1) (P = 0,05), enquanto GM (5,7 ± 0,1) foi semelhante durante a indução de SARA. A indução SARA reduziu a população de protozoários no rúmen (P < 0,05) e aumentou a concentração de cloreto no líquido ruminal (P < 0,01). Durante a SARA observou-se aumento das concentrações séricas de fósforo (P < 0,01), AST (P < 0,01) e GGT (P < 0,01), mas reduziu a de LDH (P < 0,01). Em conclusão, o protocolo utilizado para a indução de SARA foi capaz de manter o pH do rúmen entre 5,5-6,0 por períodos superiores a 48 horas. No entanto, a suplementação com monensina e probióticos não foi eficaz na prevenção das alterações nos parâmetros ruminais e séricos durante SARA. The aim of this work was to validate a protocol for induction of subacute ruminal acidosis (SARA) (Experiment 1) and test the efficiency of probiotic Saccharomyces cerevisiae or monensin to avoid pH ruminal drops in sheep (Experiment 2). In Experiment 1, six ewes were fasted for two days and then fed most with concentrate during four days. Ewes in this protocol had ruminal fluid pH below 6.0 and kept it for 75 consecutive hours. In Experiment 2, 18 sheep were distributed into three groups: Control (CG, n = 6), monensin (MG, n = 6) and probiotic group (PG, n = 6). SARA was induced according Experiment 1. PG had lower pH (5.7 ± 0.1) than CG (6.0 ± 0.1) (P = 0.05), while MG (5.7 ± 0.1) was similar to both during SARA induction. SARA induction reduced ruminal protozoa population (P < 0.05) and increased chloride concentrations in ruminal fluid (P < 0.01). In serum, SARA increased concentrations of phosphorus (P < 0.01), AST (P < 0.01) and GGT (P < 0.01), but reduced LDH (P < 0.01). In conclusion, the protocol used for SARA induction was able to maintain ruminal pH between 5.5-6.0 for more than 48 hours. However, monensin and probiotics supplementation was not effective in preventing changes in ruminal and serum parameters during SARA.

Abstract

O objetivo deste estudo foi determinar variações em parâmetros metabólicos e endócrinos de suínos machos durante o primeiro ano de vida e sua relação com a puberdade. Foram utilizados seis suínos acompanhados, de 22 a 360 dias de idade, com pesagens corporais e coletas de sangue a cada sete dias para avaliação dos níveis séricos de glicose, insulina, colesterol, albumina, ureia, cálcio, fósforo, aspartato aminotransferase (AST), gama glutariltransferase (GGT), ácidos graxos não esterificados (NEFA) e testosterona. A partir do ganho de peso e níveis de testosterona foram estabelecidos três períodos: pré-puberdade (1-5 meses de idade); puberdade (6-9 meses de idade); pós-puberdade (10-12 meses de idade), em que os níveis de testosterona foram de 0,6 ± 0,1 ng/mL, 1,8 ± 0,2 ng/mL e 1,8 ± 0,2 ng/mL, respectivamente (P < 0,0001). Foi observada correlação positiva entre a testosterona e níveis de albumina, idade e peso corporal, e correlação negativa entre testosterona e os níveis de cálcio, GGT e glicose. Os níveis de glicose diminuíram ao longo do desenvolvimento (P < 0,0001), e os níveis de NEFA foram maiores em pré-púberes (P = 0,01). A enzima GGT teve diminuição dos seus níveis a partir da puberdade (P < 0,0001), e a AST teve seus menores níveis na puberdade (P = 0,0003). A albumina apresentou maiores níveis durante a puberdade (P < 0,0001) e a ureia no período pós-puberdade (P < 0,0001). Os níveis de cálcio e fósforo apresentaram menores níveis no período pós-puberdade (P

Abstract

Background: During decades, dairy cows have been selected for its productive character, with the main focus on the breeding production, being submitted to constant conditions of metabolic disorders, likewise submitted to permanent or intermittent episodes of systemic and / or mechanical aggression, anatomofunctional of its orthopedic system, appearing locomotion injuries. The present approach brings up the variable aspect of lesions in the extensor process of the third phalanx bone, diagnosed by digital radiography, in 17 Holstein cows, with or without joint involvement, the study was conducted in a commercial farm located in the South of Rio Grande do Sul State, Brazil. Case: This case report describes the identification and the appearance of lesions on the extensor process of the third phalanx bone in dairy cattle from a commercial herd. 17 Holstein cows with three lactations, with average production in two milking of 30.67 ± 5.39 L of milk submitted to semi-extensive system, with daily walk of 2.2 km between pasture, food and milking parlor. Weekly, the cows were submitted to clinical diagnosis and radiological exploration, on two periods (pre- and postpartum), from 14 days prepartum to 50 days postpartum. All animals despite the zero score of locomotion, demonstrated no abnormalities of posture or walking, however expressed at least one radiographic change in at least one member. Thereafter, radiographic lesions were evaluated for their variety and severity, indeed animals that had only injury extensor process, with fracture and / or joint involvement were detected. In the animals evaluated in this study there was antecedent clinical record of macroscopic lesions to the digit, without lameness. Clinically, the cows manifested macroscopic signs and according to the foot condition frequency was observed: white line extension (23.72%), scissor claw (22.03%), horizontal lines (18.64%), dual sole (13.6%), wall bleeding (8.47%), crack in the wall (6.77%), corkscrew claw (5.08%) and a lower frequency of clef white line (1.69%), and the presence of lameness was not observed. Among the radiographic lesions in thoracic digits, it was found the following array, according with the frequency distribution: proliferative bone reaction in the region of the extensor process in 73.5% (nnails=34) of forelimbs from the animals, distal interphalangeal osteoarthritis (13.7%) and extensor process fracture was observed only in 2% of the digits. Discussion: In the animals evaluated in this report, there was clinical record of macroscopic lesions antecedent of aggression to the digit, without lameness, even with these bone lesions detected by digital radiographic examination, in other words, chronic lesions in the extensor process, with or without joint involvement, did not promote nociceptive signals in the locomotion of the cows, further emphasizing the importance of digital imaging in the detection of relevant subtle lesions that may subsequently lead to serious failings by the involvement of the distal interphalangeal joint. The technology of digital radiology provides a higher accuracy of diagnosis of lesions on the locomotor system, nevertheless, in dairy cattle, its use is still limited when compared to horses. Up to now, there are few studies that report the occurrence of lesions in the extensor process of the third phalanx in cattle. Extensor process lesions may be more common in dairy herds, given the absence of complementary diagnostics. [ABSTRACT FROM AUTHOR]

Abstract

The aim of this study was to determine the effect of modified glucomannan adsorbent (ADS) on the clinical, hematological and ruminal parameters in sheep subjected to diets containing aflatoxins (AFLA). Twenty two crossbred ewes (Corriedale vs Texel), aging 18 months were separated into four groups according to the addition of AFLA (1,5 PPM) or ADS (2 PPM) in the concentrate portion of the diet: animals receiving AFLA in the diet (AFLA; n=6); animals receiving AFLA and ADS in the diet (AFLA/ADS; n=6); animals receiving ADS in the diet (n=5) and control group, without addition of the ADS or AFLA in the diet (CONTROL; n=5). The diets were supplied during 42 days. Ruminal fluid was collected and analysed every seven days and the clinical evaluations (clinical examination, urinalysis, and hemogram) every 10 days. The addition of adsorbent increased the plasmatic concentration of eosinophiles. Clinical and ruminal parameters were not affected by the presence of adsorbent or aflatoxin into the diet. The modified glucomannan adsorbent influenced the leukocyte response of sheep, but no effect on ruminal function and clinical parameters. O objetivo deste estudo foi determinar o efeito do adsorvente (ADS) glucomanano modificado sobre parâmetros clínicos, hematológicos e ruminais de ovinos submetidos a dietas contendo aflatoxina (AFLA). Foram utilizadas 22 ovelhas mestiças (Corriedale e Texel), com 18 meses de idade. Os animais foram divididos em quatro grupos, de acordo com a adição de AFLA (1,5 PPM) ou ADS (2 PPM) na fração concentrada da dieta: animais recebendo AFLA na dieta (AFLA; n=6); animais recebendo AFLA e ADS na dieta (AFLA/ADS; n=6); animais recebendo ADS na dieta (ADS; n=5) e grupo controle, sem adição de ADS ou AFLA na dieta (CONTROLE; n=5). As dietas foram fornecidas por um período de 42 dias. Foram realizadas coletas de fluido ruminal a cada sete dias e avaliações clínicas (exame físico geral, urinálise e hemograma) a cada 10 dias. Quanto ao perfil leucocitário, a suplementação com adsorvente aumentou a concentração plasmática de eosinófilos. Os demais parâmetros clínicos e ruminais não foram influenciados pela presença do adsorvente ou da aflatoxina na dieta. Assim, o adsorvente glucomanano modificado influenciou a resposta leucocitária de ovinos, porém sem efeito na função ruminal e nos parâmetros clínicos avaliados.
