Avaliação enzimática muscular em eqüinos (Equus caballus, Linnaeus, 1758) em treinamento para vaquejada, sob repouso e pos-atividade física.

Abstract

A study conducted at Training Center Joames Bacalhau, Ingá-PB and the Laboratory of Clinical Pathology of the Veterinary Hospital / CSTR / UFCG, Patos - PB, from August to September / 2008, to determine the serum-enzyme activity of muscular horses used in vaquejadas on the condition of rest and groups - physical activity. Were used tem horses in age from two to 13 years old, race of Fourth Mile and Mestiçagens, under system of creating semi-intensive, diet based on forage, consisting of native grassland and grassy - Brachiara spp and Grass (Cynodon spp) and, offers of concentrated industrial pelleting, in accordance with the rules of preparation. The experiment was done with randomized design in pre-trial stages and final, the second group of horses, constituted under the preparatory stage of training daily. The blood samples for biochemical measurement, collected at intervals of twelve hours and measured the rates of serum enzyme through commercial kits (LABTEST), in Analyzer semi-automatic - Bioplus 2000. It suffers from the condition of rest, mean values and standard deviation of Creatine phosphokinase (CPK), Aspartate aminotransferase (AST), Lactate dehydrogenase (LDH), respectively, of 267.50 U/L ± 45.14, 164.75 U/L ± 111.23 and 609.50 U/L ± 216.18; while, the findings of CPK (489.2 U/L ± 180.47), AST (190.1 U/L ± 168.28)and of LDH (814.85 U/L ± 215.77) registered pos - physical activities were markedly higher. It follows that the values of serum muscle enzyme-horses used in vaquejada are higher in contingencies predominant groups - physical activity, with significant interaction between diet and intense physical activity.
