This study aimed to evaluate the possible adverse effects of administering oral therapeutic firocoxib on gastric mucosa, hematological parameters, coagulation cascade, and hepatic and renal biochemistry in healthy horses. Nine clinically healthy Arabian horses, approximately nine years old, received 0.1mg/kg of oral firocoxib for 14 days. Before beginning treatment, a gastroscopic examination was conducted, and venous blood samples were obtained for laboratory tests on D0. Follow-up blood samples and gastroscopic examinations were taken on D7 and D14 after starting treatment and one week after completing treatment on D21. No changes were found in the gastroscopic and hematological tests. Additionally, coagulation and serum biochemistry levels remain between normal values for this particular species. However, the in...

Nine clinically healthy Arabian horses, approximately 9 years old, received 0.1 mg/kg of oral firocoxib for 14 days. The gastroscopic examination was conducted 1 day before starting treatment (D0) and two days after the last blood collection (D23). Venous blood samples were obtained for laboratory tests on day 1, immediately prior to the initiation of treatment (D1), after 7 and 14 days of treatment (D7 and D14), and 7 days after the conclusion of treatment (D21. No changes were found in the gastroscopic and hematological tests. Coagulation and serum biochemistry levels remain between these species’ aver...

However, despite the prominence of this sport, there is currently no satisfactory evaluation of the physical fitness of its horses. Our study compared two standardised exercise tests (specific and nonspecific for show jumpers) to determine the importance of a show jumping specific evaluation test. Sixteen horses were divided into two performance groups (high and low performance), and all horses performed standardised exercise tests without jumps (SET1) and with jumps (SET2). Heart rate, blood lactate, glucose, blood gas, haematological parameters, and plasma ions were measured before and after the tests, and performance indices were calculated. Both exercise tests (SET1 and SET2) resulted in changes in nearly all measured variables that were expected, based on other studies, for the duration and nature of the exercise performed. Differences between the two performance groups were observed for lactate and glucose, as we...

O objetivo do presente estudo foi verificar o perfil protéico sérico de parâmetros relacionados à imunidade de equinos jovens no período perinatal, verificando-se a transferência de imunidade passiva. Oito animais desmamados há um dia, formaram o Grupo 1 (G1), enquanto vinte animais desmamados há mais de trinta dias formaram o Grupo 2 (G2). A concentração sérica de proteína total foi determinada por refratometria. Para o fracionamento das proteínas, utilizou-se eletroforese em gel de acrilamida. Os resultados obtidos foram submetidos à análise de medidas repetidas e ao teste Tukey…

Equestrian show jumping is an Olympic sport and studies on the fitness levels of jumping athlete horses have yet to be conducted. The BH breed was developed for jumping competitions and has been featured in international competitions. Objective. BH horses were divided into two groups with different fitness levels and were compared using the IJT. We determined their respective muscle fiber compositions. These compositions were then correlated with the plasma lactate produced during the IJT. Methods. Fifteen horses (11.6 ± 3.1 ys) were distributed into two groups: lower fitness (LF, n=8) that jumped up to 0.90 m and higher fitness (HF, n=7) that jumped up to 1.20 m. The IJT consisted of three steps with forty jumps each at increasing heights (40, 60 and 80 cm). Lactate was determined by YSI 2300. A percutaneous muscle sample was obtained from the Gluteus medius. Myofiber types were determined using myofibrillar adenosine triphosphatase (mATPase) and nicotinamide adenine ...
