Perfil bioquímico sérico de equinos submetidos a prova de esforço físico

Abstract

ABSTRACT II: Endurance race is one of the most competitive emerging equestrian sports in the world. Laboratory tests have become essential in the evaluation of the competition horse and therefore, this study aimed to evaluate the profile of proteins, metabolites, minerals and enzymes in serum of horses subjected to endurance race. Blood samples were collected from 31 Mangalarga Marchador horses during the Cavalgada Sul Minas, with the percurse of 90 KM between the cities of Lavras and São João del Rey, Minas Gerais. Samples were collected in the first, third and fifth day of competition. In each serum sample were determined creatinine, urea, gamma glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, creatine kinase, triglycerides, cholesterol, total protein, albumin and globulin. It was observed that the majority of the analyzed elements remained within the normal physiological patterns except CK and ALT which showed elevated, and cholesterol, which showed reduced. A significant difference was observed in serum in the three stages of total protein, globulin, ALT and cholesterol. The elements albumin, CK, creatinine, uric acid, chloride, total protein and globulin increased from first to second stage, decreasing in the third. ALT increased significantly at all three stages, while there was a decrease of cholesterol levels. At some point there were statistical differences from GGT, increasing exaggeratedly at the second stage, AST, triglycerides, urea, sodium and potassium sera levels appearing differents in the third stage. The test ride causes biochemical changes in horses, especially in the elements ALT, cholesterol, total protein and globulin. ABSTRACT III: Training is essential to prepare the body for intense changes occurring in athletic performance. The effect of training depends on the duration, type, frequency and intensity of athletic training. The objective of this study was to evaluate the profile of proteins, metabolites, minerals and enzymes in serum of equine athletes Polo, correlating with those in professional animal training. Blood samples were collected from 82 Thoroughbred horses of both sexes, at Haras San Jose, located in Santa Rosa of Viterbo - SP. We performed a single collection in the morning, before training the animals, and these were divided into two groups. Group I animals in training, those who do not participate in the proof of Polo, and group II, animals professionals who already practice the sport regularmente.Foram determined in each sample serum albumin, calcium, total cholesterol, creatinine , alkaline phosphatase, phosphorus, gamma glutamyl transferase, total protein, aspartate aminotransferase, alanine aminotransferase, triglycerides, HDL cholesterol, urea, and magnesium. All elements analyzed were within the normal physiological patterns. When confronted the two groups was statistically significant for lacatato, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, urea, creatinine, phosphorus and potassium. When confronted animal sex statistical difference was observed for globulins, creatinine kinase, lactate dehydrogenase, aspartate aminotransferase and phosphorus.
