“…Apesar disso, 42% dos animais examinados quanto ao RCC apresentaram índices abaixo do normal. A diminuição da taxa do RCC, ou seja, uma menor variação entre as concentrações matutinas e vespertinas de cortisol sérico é um indicativo de que o cavalo não está conseguindo enfrentar a situação estressante imposta a ele (ALEXANDER & IRVINE, 1998). Por outro lado, alguns autores sugerem que a estereotipia seja uma forma que o animal encontra para lidar melhor com o estresse (COOPER & NICOL, 1993;MCGREEVY & NICOL, 1998).…”

“…The association of disease with gastric ulceration may not be related to stress per se. Cortisol has been well documented as a hormonal indicator of stress across multiple species, indluding horses (Alexander and Irvine, 1998). Cortisol concentrations did not differ between normal foals and those stressed by disease (Furr et al, 1992).…”

Equine gastric ulcer syndrome (EGUS) has been reported to occur in 40% to over 90% of horses across multiple equestrian disciplines. The objective of this study was to evaluate the effect of trace mineral supplementation on gastric ulcers in exercising yearling horses. Twenty-one Quarter Horse yearlings, 15 to 18 mo of age, were randomly assigned to 1 of 3 treatment groups. The control group received no supplemental trace minerals, the inorganic group received supplemental sulfated trace minerals, and the organic treatment received supplemental amino acid complexed trace minerals. The trial consisted of 3 consecutive 28-d periods, separated by 5 d of diet acclimation. The basal ration included a 14% CP textured concentrate, with coastal Bermudagrass hay fed in Periods 1 and 3 and alfalfa consumed in Period 2. In Periods 1 and 2, horses were exercised on a mechanical horse-exerciser, but were lunged or underwent training in an undergraduate course in Period 3. At the end of each period, horses were transported for 6 h, 5 d before being endoscopically examined to assign ulcer scores. Data were analyzed as repeated measures using the mixed procedure of iv SAS, with the model including fixed effects of treatment, period, and their interaction (SAS 9.2). All P-values < 0.05 were considered significantly different.

“…It has also been suggested that d-ROMs concentration rises under stress such as transportation [9] and shelter [10] in the studies using dogs. Because it is well known from long ago that there are horses feeling stress [31], the influence of stress should be also investigated on the horses. Because there are few reports to date on d-ROM and BAP levels in horses, further study would be necessary to describe more precisely how d-ROM and BAP levels change under unusual conditions.…”

Diacron-reactive oxygen metabolite (d-ROM) and biological antioxidant potential (BAP) levels in the serum of horses were measured (ponies, n = 15; thoroughbred, n = 31; other full-sized horses, n = 7). The mean d-ROM levels in horses were significantly higher (p < 0.001) than those in dairy cattle (n = 25) and dogs (n = 31). However, d-ROM levels in horses were lower than the standard levels reported in humans. When d-ROM and BAP levels were plotted graphically, the points for horses with a disease (ringbone in 1 Japanese sports horse, cellulitis in 1 thoroughbred, melanoma in 1 Lipizzaner) fell outside the group of points for other (non-diseased) horses. A similar separation was seen (using data from other authors) for a horse with Rhodococcus equi, a horse following castration surgery, and a mare following delivery. These results, comparing horses, other animals, and humans, are interesting from the standpoint of comparative medicine, and they contribute to the sparse literature available on d-ROM and BAP levels in animals. Because the level of d-ROM and BAP levels were changed depending on the situation of health, those indexes are promising as indices of health in horses.
