Several studies have shown a major development in height and cannon bone circumference in foals from birth to weaning and from different breeds. However, in Brazil, there is little information about foal development. For this reason, this study has used data on foals from seven different farms in Pernambuco, Northeast Brazil, where horses have a major economic importance. The aim of this study was to compare foal’s development from four breeds and to develop a regression formula in order to estimate such development. It was used data from 210 suckling foals (Arabians n = 18, Campolina n = 86, Mangalarga Marchador n = 42 and Quarter Horses n = 64), raised in similar management practices. Their height at withers, heart girth, and cannon bone girth were measured monthly from birth to weaning. Data we reanalyzed by ANOVA and Tukey Test, with P established in 5%. The highest mean of height at withers was observed in the Arabian foals, and it was similar to Campolina and Mangalarga Marchador foals. The last breed presented a higher percentage of gain in height (~36%) and higher heart girth. On the other hand, Campolina foals had the highest mean of cannon bone girth. There was a significant interaction between breed and development phase in heart and cannon bone girths. All regression for mulas obtained from this data was very significant, and it was showed that they can predict height at withers in the four breeds studied. Heart and cannon bone girths showed medium value of R2 and large significance. It is important to highlight that fetal programing produces significant impact on foal development, even after weaning. So, this study would have observed some more changes if its scope had been extended beyond this phase.

There is little information about the bovine behavior and welfare during transportation and vaquejada race competitions. To test the hypothesis that the transport and racing of bovines produce chronic stress during these events, a study was performed to evaluate the behavior of bovines used for vaquejada races. Evaluations of cattle (n = 80) occurred on transportation (before, immediately, and 8 hours after transportation), and three days at Vaquejada Park (1 hour before, immediately, and 1 hour after the vaquejada race). Evaluators used a behavioral repertoire based on an ethogram for bovines and were previously trained. They used an observational and noninvasive method for one hour and applied a visual scanning method at transportation and for three days at the races. The results for pre-transport had greater idleness (102.9%), head/tail movements (57.4%), and agitation (49.8%). After transport, idleness (69.7%) was reduced, and agitation (79.5%) increased. Eight hours after this, sodomy/mounting/dominance (118.1%) was higher, followed by head/tail movements (92.8%), lying down (63.3%), and fatigue (53.3%). The results of vaquejada races revealed high feeding rates before and after races on the three evaluation days (53.6% - 30.0%), followed by rumination (72.0% - 44.5%). On all the evaluation days at the races, agitation was higher immediately after the races (87.9% - 66.1%). In conclusion, it was observed that the animals increased the frequency of behaviors indicative of acute stress immediately after transport and races but were able to recover the characteristic behavior a few hours after acute stress when transport and races followed the current official rules for both. Maintaining management standards for transport and vaquejada races, currently adopted, can reduce the impact on welfare and can be improved with regular scientific evaluations of the cattle involved to improve welfare through good practices.

The vaquejada race is a sport with animals which has the greatest socio-economic impact in Brazil and is responsible for generating an intense cultural and economic movement. However, this activity has been the subject of questions about well-being involving the environmental and mental comfort conditions offered to equine and cattle interactions. It is necessary to perform technical evaluations of the cattle involved on the basis of scientific study to better understand the processes of sport and, with this, promote their evolution on good welfare practices in the 21st century. Therefore, to test the hypothesis that the use of the official rules of the vaquejada where cattle use a protective harness on the tail protects the cattle’s tail from injuries in this region that compromise health. Before, during and after races, a study was developed that aimed to perform a general and radiological clinical evaluation in the proximal coccygeal region in cattle that ran in a modern cattle stall. Forty male bovines were evaluated (average: 2 year-old and 420 kg). Oxen were subjected to clinical and radiological examination before and after racing with official rules. Results of the clinical and radiological evaluations performed by veterinarians, did not observe clinical occurrences before and after the races in the 40 cattle evaluated. The increase in heart and respiratory rates was a reflection of temporary management stressors, as the animals returned to the feeding/rumination/interaction pattern after running in the rest pen. The radiographic findings in the tail, represented by the reduction of the intervertebral space and areas of subcutaneous radiolucency, suggest technical artifacts derived from

In recent decades, the intensity of training and equestrian competitions has significantly increased, thus the assessment of the well-being of the equine athlete has become essential in all equestrian modalities. The aim of this study was to ascertain whether equine athletes submitted to a vaquejada simulation test (VqST), comprised of three races, presented changes in blood biomarkers related to stress and health status. Fourteen healthy Quarter Horses, used as pull horses in this equestrian modality, were evaluated. Ten animals were submitted to the VqST and the remaining four were used as a control group. Blood samples were collected pre-test (during fast), immediately after, and at 1, 4 and 24 hours of recovery. The assessed blood biomarkers included cortisol, interleukin (IL)-6, IL-1β, iron, urea, creatinine, and gamma-glutamyl transferase (GGT) concentrations and results were analyzed using One Way ANOVA (time) with the SigmaStat 13.0 software. No differences between sample times were detected in both groups (p > 0.05) and no differences were found between groups (p > 0.05). The results suggest that all horses were well conditioned for the level of effort imposed by the three vaquejada races. The adaptation to physical exercise may enable the regulation of the acute response to stress in the tissues involved in the exercises, with no differences being observed in stress and health biomarkers, such as IL-6, IL-1β and cortisol. In conclusion, well-conditioned vaquejada horses exhibit a balanced regulation of biological processes, which contributes an increased athletic longevity and better quality of athletic life.

Infrared thermography (IRT) has emerged for evaluation of animal welfare. To test the hypothesis that cattle subjected to vaquejada increased temperature in the eye (CLO) and tail due to physical effort, a research was developed that aimed to measure maximum surface temperature in the CLO and base of tail using IRT. Eighty Nellore cattle were used, which were subjected to physical effort in three periods (morning, afternoon and night). IRT was performed at CLO and base of tail, in rest pen/corral (control) and during the vaquejada (pre- and post-run). Tails’ analysis was divided in 3 points (E1, E2 and E3). ANOVA and Tukey’s test (p < 0.001) were used for analysis. Temperatures were higher in morning and afternoon and different from those at night on control (p < 0.001). During vaquejada with one run, CLO was higher in pre-run, followed by a slight reduction in post-run (p < 0.001). Analyzing temperatures variations at tail, higher temperatures were observed in the morning, followed by the evening and night (p < 0.001), but without differences within the pre- and post-run periods. Temperatures at tail’s points were higher in morning period in cattle with two runs (p < 0.001). Finally, it was concluded that there were no increases in CLO or at tail’s points after vaquejada races. The IRT method was efficient in determining surface temperatures in CLO and tail points in cattle under the same conditions and may be a good noninvasive method for clinical and welfare assessments.

The aim of the present study was to compare two protocols of Agar Gel Immunodiffusion (AGID) that can be used to diagnose Equine Infectious Anemia (EIA). Different volumes of reagents and support for agar gel were used, as recommended by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and the World Organization for Animal Health (OIE). Equidae sera samples (n = 1000) were tested using a national commercial kit and different volumes (i.e. 25 μL—MAPA and 50 μL—OIE) of reagents and standard sera. Antigen was used as recommended by MAPA. The results were assessed by two operators, 48 hours after beginning the test. At the end of the experiment, a Kappa index of 1 was obtained by the operators, for the interpretation of the results and for the different volumes of reagents used. Similar results of agreement (Kappa index = 1) were obtained when using slides or Petri dishes as support for the agar gel. In both cases, an almost perfect agreement was achieved, suggesting that the use of different supports does not affect the results. These findings indicate that both protocols (MAPA and OIE) can be used to diagnose EIA.
