Abstract
The objective of this study was to evaluate the serum proteinogram, identifying and quantifying the acute-phase proteins (APPs) of horses used in show jumping activity with obstacles of a meter in height. As it is an equestrian sport that involves high intensity and excessive impact, the possibility of injury is relevant. The serum of 10 horses was evaluated in a competition for beginners. The material was collected at rest (T0), immediately after exercise (T1), 30 minutes after the effort (T2), 1 hour after the effort (T3), and 24 hours after the effort. Acute-phase proteins were separated by polyacrylamide gel electrophoresis and their concentrations determined by computerized densitometry. Protein identification was performed using mass spectrometry. The data were evaluated using analysis of variance for repeated measures, considering the level of significance of P < .05. Eight APPs were identified: α2-macroglobulin (α2-macro), ceruloplasmin (Cp), transferrin (Trf), albumin (Alb), α1-antitrypsin (α1-atp), haptoglobin (Hp), acid glycoprotein (AGP), and apolipoprotein A1 (Apo A1). There was a difference in Cp, AGP, and Apo A1 between moments. As the other proteins were not influenced by exercise, they were established as a valuable resource in the monitoring of inflammatory processes and an important complementary element in controlling the impact of training on the animals, thus guaranteeing their welfare.
