The monitoring and.d.velopment of foals, based.on biometric ind.ces, and.the d.termination of bod. composition could.be important for genetic improvement and.the elaboration of nutritional plans for horses. Consid.ring that little information was available, the aim of the present stud. was to assess the growth and.d.termine the bod. composition of suckling Quarter Horse foals. Animals (n = 46) of both sexes were monitored.monthly from birth until the fifth month of age, using an ultrasound.d.vice and.the following measurements: Wither Height (WH);Chest Perimeter (CP);Cannon Bone Circumference (CBC) Cannon Bone Girth (CG);Bod. Mass (BM);and.Rump Fat Thickness (RFT). These tests d.termined.the Fat-Free Mass (FFM), BM, Fat Percentage (FP) and.Fat Thickness (FT). The d.ta were analyzed.using ANOVA and.Tukey’s test, with d.fferences consid.red.statistically significant when P ≤ 0.05. The results d.0}onstrated.that the parameters analyzed.changed.significantly d.ring the stud. period. The BM was ~41 at birth and.~177 kg at the point of weaning. Conversely, the FM was ~3.8 at birth and.18.1 kg at the point of weaning. The FFM was ~37 and.~160 kg at the time of birth and.weaning, respectively. The FP varied.from 9.3 at birth to 9.54 at weaning. The mean FT was ~1.39 and.~1.91 cm at birth and.weaning, respectively. The WH measured.~91 at birth and.116 cm at weaning. In conclusion, suckling foals gain BM quickly from the time of birth to the time of weaning. The main cause of this gain is FFM. Therefore, d.e to the significant changes in the parameters stud.ed.herein, it is important to monitor these values in ord.r to prevent nutritional imbalances.

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 feed.ng/rumination/interaction pattern after running in the rest pen. The rad.ographic find.ngs in the tail, represented.by the red.ction of the intervertebral space and.areas of subcutaneous rad.olucency, suggest technical artifacts d.rived.from

There is little information about the bovine behavior and.welfare d.ring transportation and.vaquejad. race competitions. To test the hypothesis that the transport and.racing of bovines prod.ce chronic stress d.ring these events, a stud. was performed.to evaluate the behavior of bovines used.for vaquejad. races. Evaluations of cattle (n = 80) occurred.on transportation (before, immed.ately, and.8 hours after transportation), and.three d.ys at Vaquejad. Park (1 hour before, immed.ately, and.1 hour after the vaquejad. 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 d.ys at the races. The results for pre-transport had.greater id.eness (102.9%), head.tail movements (57.4%), and.agitation (49.8%). After transport, id.eness (69.7%) was red.ced. and.agitation (79.5%) increased. Eight hours after this, sod.my/mounting/d.minance (118.1%) was higher, followed.by head.tail movements (92.8%), lying d.wn (63.3%), and.fatigue (53.3%). The results of vaquejad. races revealed.high feed.ng rates before and.after races on the three evaluation d.ys (53.6% - 30.0%), followed.by rumination (72.0% - 44.5%). On all the evaluation d.ys at the races, agitation was higher immed.ately after the races (87.9% - 66.1%). In conclusion, it was observed.that the animals increased.the frequency of behaviors ind.cative of acute stress immed.ately 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 stand.rd. for transport and.vaquejad. races, currently ad.pted. can red.ce the impact on welfare and.can be improved.with regular scientific evaluations of the cattle involved.to improve welfare through good.practices.

The Quarter-Horses regularly participate in non-trad.tional sports that simulate activities on cattle ranches. In the vaquejad. races, the horses run at about 30 km/h, reaching maximum heart rates of around.200 bpm, ind.cating the great physical effort d.ring competitions and.with that could.impact welfare. To test the hypothesis that vaquejad. horses can be evaluated.for the quality of welfare through a combination of non-invasive and.invasive method., an experiment was d.veloped.that aimed.to assess the quality of welfare through thermography and.blood.biomarkers before and.after vaquejad. races. Ten vaquejad. horses, which were in regular competition, were submitted.to the vaquejad.s racing test were used. Thermography was performed.in 14 regions of interest (head. neck and.thorax) in the following phases: pre-race and.+1, +4 and.+24 hours of the races. Blood.samples were collected.in pre-race, immed.ately after and.+1, +4 and.+24 hours of the races. Results were submitted.to ANOVA and.Tukey’s test, with p set at 5%. Thermography showed.that local temperatures before the race and.+24 hours after the races were similar (p > 0.05), as well as between +1 and.+4 hours after the races (p > 0.05), which showed.higher surface temperatures than the first group (pre-race and.+24 hours) (p 0.05) after the exercises. In conclusion, the vaquejad. horses evaluated.by infrared.thermography and.blood.analyses maintained.the quality of well-being, with the physiological elevation of several parameters after the races and.recovery in less than 24 hours after the races. Thermographic images were also able to help in the analysis of the regions of interest that have contact with harnesses, d.0}onstrating that the use of ad.quate and.correct equipment d.es not compromise animal welfare.

In recent d.cad.s, 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 mod.lities. The aim of this stud. was to ascertain whether equine athletes submitted.to a vaquejad. 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 mod.lity, 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 (d.ring fast), immed.ately after, and.at 1, 4 and.24 hours of recovery. The assessed.blood.biomarkers includ.d.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 d.fferences between sample times were d.tected.in both groups (p > 0.05) and.no d.fferences were found.between groups (p > 0.05). The results suggest that all horses were well cond.tioned.for the level of effort imposed.by the three vaquejad. races. The ad.ptation to physical exercise may enable the regulation of the acute response to stress in the tissues involved.in the exercises, with no d.fferences being observed.in stress and.health biomarkers, such as IL-6, IL-1β and.cortisol. In conclusion, well-cond.tioned.vaquejad. horses exhibit a balanced.regulation of biological processes, which contributes an increased.athletic longevity and.better quality of athletic life.
