The current paper aims to characterize the honey derived from the aroeira tree (Myracrodruon urundeuva Allemão) through pollen and physicochemical analysis. The samples (15) were obtained directly from beekeepers of the State of Piauí throughout the months of August and September 2019, and then identified by number, location and harvest date, subsequently being submitted to melissopalinological and physicochemical analysis (acidity, pH, humidity, reducing sugars, apparent sucrose content, ashes and color). As a result, it was noted that of the 15 samples analyzed, 10 were identified as monofloral honey from the aroeira tree. It’s worth noting that the samples presented a low species variety in their pollinic spectrum, and 13,3% of the samples were determined to be 100% from the M. urundeuva pollinic type. Such information allows the inference of a regional potential for the production of the aroeira tree monofloral honey. The aroeira tree honey presented the following physicochemical characteristics: acidity (26,93 meq/kg ± 2,85), pH (3,48±0,30), humidity (16,4%±0,02), dark amber color, reducing sugars (70,9%±1,58), ashes (0,13%±0,4), apparent sucrose content (0,93%±0,14). The results are in agreement with the limits established by the current legislation. The honey presented physicochemical characteristics similar to other monofloral aroeira tree honeys originated from semi-arid regions. It was possible, therefore, to establish physicochemical standards for the aroeira tree honey produced in Piauí, contributing to the valorization of the semi-arid’s monofloral honey.

Foreign body obstructions are a common cause of colic in carthorses. The high incidence may be due to poor feeding practices and to the fact that most of these animals live in inadequate sanitary conditions. This paper reports six cases of colic caused by foreign bodies in carthorses presented to the Veterinary Teaching Hospital of the Federal University of Paraná. Plastic bags and enteroliths were found in the small colon, large colon, transverse colon and rectum. All animals presented abdominal discomfort and hypotonicity. Five horses underwent surgery and one was treated medically. The paper emphasizes the importance of auxiliary diagnostic methods the mainly affected portions of the intestine and the risk factors associated to the colic syndrome. [ABSTRACT FROM AUTHOR]

This work aims to contribute to the study of alternative forms of control of Rhipicephalus microplus through the fungus Metarhizium anisopliae. In order to evaluate the effect of the fungus on bovine tick protease activity, 80 engorged females of R. microplus were divided into control and treatment groups (48 hours of treatment). The treated females were immersed in the conidial suspensions and the controls in sterile distilled water plus 0.1% Tween 80. Females were dissected and the intestinal lavages were washed, dried on filter paper for removal of excess liquid and weighed. They were homogenized and a protein concentration determined. The presence of proteolytic activity in the intestinal extract was measured by the hydrolysis of the protein substrate hemoglobin and the quantification of tyrosine. In the values of pH 4.0 and 5.0 were found an increase of the activity against fungus use. At these pH values there is mainly presence of cysteine and aspartic protease.When using a cysteine protease inhibitor (dithiothreitol), inhibition of 74% and 54% of the proteolytic activity was observed in the treated and control groups, respectively. Meanwhile, the other cysteine protease inhibitor, phenylmethanesulfonyl fluoride, inhibited 86% and 80% of proteolytic activity in treated and control groups, respectively. It was possible to conclude with this study that it has a majority activity of cysteine proteases acting in the intestine of R. microplus and that this activity can be increased in the presence of the entomopathogenic fungus. This increase, in turn, can occur by proteases of the fungus or the tick defense mechanism, which suggests that M. anisopliae may prove to be a form of effective control for the tick.

Murine mycoplasmosis is an infection that still represents a challenge to animal testing throughout the world. Mycoplasma pulmonis is the agent of murine respiratory mycoplasmosis, a chronic course disease, slow and persistent throughout the animal's life. The objective of this paper was to give an overview on biological characteristics, disease, diagnostic methods and difficulties for prevention and control of this microorganism. Rats and mice are used worldwide in biological research, and when under sanitary and genetic standardization, provide the researcher important models for understanding of various biological mechanisms. However, these species can be infected by pathogens that, when introduced in the colony, affect production and experimental results. Among the major infections that affect rodents, mycoplasmosis is one of the most important because it produces severe respiratory and reproductive problems, affecting the colony and hindering the obtaining of pathogen-free animals. Even with the advent of equipment such as racks of individually ventilated cages, the occurrence of infection is still 100% in conventional colonies and 3.2% to 20% in colonies maintained under barriers.

The palmar nerve block is a technique which enables performing diagnostic lameness and analgesia in the distal region of the equine forelimb. This paper aimed to compare the efficacy of bupivacaína 0,5% (BUPI) and ropivacaine 0.5% (ROPI) without vasoconstrictor in palmar nerves, guided by electrical stimulation. After placing horse bar shoe lameness inducer in the right forelimb, providing lameness grade (CG) 3, and location of the palmar nerve with electrical stimulator, five healthy adult horses and noncarriers of inflammatory processes, underwent infiltration of 5 mL of BUPI and ROPI without vasoconstrictor in each nerve, viewing the GC every 15 minutes until the time of return to GC 3. All animals participated in the two groups, with an interval between blocks of 45 days. The following parameters were compared anesthetic response: time sensory latency (TL), time of latency to maximum effect (TLM), time sensory effect (TE) and time of duration of maximum effect (TEM) by using the Wilcoxon test. The technique for electrical stimulation was successful in 100% of horses. The TL of BUPI was five minutes, ten minutes shorter than the ROPI (p <0.05), showing that the first drug has faster action to perineural diagnostic blocks or pre-surgical analgesics. Regarding the TLM and TEM no difference between the anesthetics (p> 0.05), however, compared to the TE, BUPI was time of 230 minutes, also showed longer duration of analgesia than ROPI (p <0.05). From this research, it is concluded that the use of bupivacaine showed superior analgesic effects of ropivacaine to palmar nerves block of the healthy horses. [ABSTRACT FROM AUTHOR]

The present study aimed to assess the effects of environmental enrichment (EA) on the welfare of mice in maternity of a vivarium. For this, Swiss mice of the maternity of the Positivo University vivarium were separated randomly into two groups of six females each, one group with enrichment (CE), consisting of paper for making the nest, and another group without enrichment (SE); two females were placed in each box. The behaviors evaluated were exploratory (EXP), agonistic (AGO), self-care (CUI), interaction with enrichment (IE), interaction with pups (IF), interaction between mothers (IM) and food (ALI), compared in general and throughout nine days of filming. Regarding the general comparison, the AGO behavior was lower in the CE group (P = 0.047); however, the median was equal to 0% for both groups. Throughout the days, the behaviors EXP, IF, and ALI in both groups showed differences (P<0.05), with decreasing length of EXP and increasing length of IF and ALI. There were differences (P<0.05) in the median of CUI and IM, indicating variation throughout the days on the SE group, and no difference on the CE (P>0.05), meaning that in CE, CUI and IM occurred in a more continuous way. Still in the CE group, there was variation (P<0.05) of IE, showing a decrease throughout the days, from 29% in the first day to 1% on the last day. The CE group showed a greater variation in the expression of the AGO behavior (P<0.05), while in SE there was no difference (P>0.05), indicating that AGO did not vary throughout the days. We conclude that EA improves the interaction between animals, decreasing agonistic behaviors and encouraging the natural nesting behavior. Due to the positive impact, most studies on ways to EA for mice are relevant. [ABSTRACT FROM AUTHOR]

Hip dysplasia is one of the most common joint disorders in dogs. Acetabular denervation is a surgical technique performed in dogs with hip dysplasia associated to pain in this joint. The aim of this paper was compare the results of two different approaches, lateral and ventral performed in 24 dogs to access the hip joint. We evaluated immediately before surgery and after 14, 30 and 60 days postoperatively the following aspects: lameness, muscle atrophy, crackling of the joint, pain and tendency to dislocation of the femoral head in the Ortolani maneuver. Quality of life was evaluated after 60 up to 360 days postoperatively. There were no significant statistically difference between ventral or lateral surgery approaches based on the parameters evaluated. There was a good improvement in lameness from 60 days after surgery either in quality of life in the owner's perspective. We concluded that both surgical approaches are feasible for acetabular denervation in dogs with significant decrease in lameness after 60 days and increased quality of life at 60 up to 360 days postoperatively.

Thousands of people use the cart pulled by horses as a means of work or supplemental income in the world. But there are few studies involving the animal biometric characterization and wagon measures, seeking classify equids for traction capacity and propose scientifically sound discussions about the load capacity per animal, thus reducing maltreatment. The aim of this paper was to determine the zoometric standard, typology and wagon measures of the 234 cart equids from Arapiraca city, Alagoas state, Brazil. Morphostructural linear and perimeter measurements were obtained, calculating the zoometric indexes: body index, estimated weight, dactyl-thoracic index, work walking index and work galloping index. The variables were subjected to analysis of variance and means test (Skott-Knott 5% probability). The mules represented 76% (179) of the animals, horses 21% (49) and donkeys 3% (6). In all measurements and indexes studied, except where the donkeys body index had the highest average, there is a statistical difference (P <0.05) between species with the highest values always with horses, mules and followed by donkeys. There are no adequate in relation to the wagon measures, verifying difference (P <0.05) only for vehicles pulled by donkeys. The horses and mules used by drivers of carts are classified as small equids, with a propensity to a slight traction. [ABSTRACT FROM AUTHOR]

This research paper aimed to evaluate the hematological changes related to natural gastrointestinal parasite load in infected horses and donkeys on the island of Sao Luis, MA. The animals selected were 57 horses and 37 donkeys, mixed breed, varied ages and weight, were randomly selected. Fecal examinations were performed by Willis-Mollay, Gordon-Whitlock, and Robert O'Sulivan methods. The animals were divided into four groups according to parasitic load and animal species in: group 1 - donkeys with EPG ≤ 500; group 2 - donkeys with EPG > 500; group 3 - horses with EPG ≤ 500, and group 4 - horses with EPG > 500. The results obtained in eggs per gram of feces counting (EPG) showed a variation from 0 to 3,000 EPG for horses and 0 to 6,900 for donkeys; the larval culture results in both species showed a higher frequency of Cyathostominae - Strongylus vulgaris association which resulted, mainly in the group of donkeys with ≤ 500 EPG, high average values in leukocyte, rod cells, eosinophils, and lymphocytes total counting. Such findings indicate the existence of mild leukocytosis with eosinophilia associated or not with the elevation of other cells, showing that eosinophilia was a marker for the presence of intestinal parasitism for donkeys, even when they have low values of EPG counting.

Polo is one of the most ancient equestrian sports. It was introduced in Brazil in the twenties and has increased since then. The respiratory tract is essential for health and athletic performance in horses, and respiratory disease cause considerable organic and economic losses. Exercise Induced Pulmonary Hemorrhage is within the most important respiratory diseases. Tracheal wash cytology is more specific than only endoscopy in the diagnosis of this disease. Considering that very few clinical studies have been conducted on polo horses, the aim of this paper is to apply the total hemosiderin score (THS) in tracheal wash cytology of polo horses. A total of 37 polo horses were evaluated 30 to 90 minutes after the game. The animals were divided in 2 groups considering the presence of blood on endoscopic examination post-exercise. According to score values proposed by Doucet and Viel (2002), EIPH occurred in 11.5 and 27.2 % of animals in group 1 and 2, respectively. Although apparently asymptomatic, the horses showed cytology profile compatible with EIPH in relevant proportions, which confirms this disease as an important cause in the diagnosis of poor performance. Since the THS was developed for BAL, new studies must be done to determine the THS cutoff in tracheal wash. [ABSTRACT FROM AUTHOR]
