Abstract

DITTRICH, Rosângela Locatelli et al. Serum biochemical in thoroughbred horses supplemented with fat. Cienc. Rural [online]. 2000, vol.30, n.4, pp. 631-634. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782000000400012.

This experiment determined lhe concentrations of blood glucose, urea, GGT (gama glutamyltransferase), creatine kinase (CK), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in horses after the exercises, with normal diet and additional dietary fat. It was used the 4x4 Latin square design. The four diets were Tl-normal diet; T2-normal diet with 10% com oil; T3-nonnal diet with 10% coconut oil; T4-nonnal diet with 5% com oil and 5% coconut oil. There were no signifi cam changes in glucose, urea and GGT leveis due to diet. The serum concentrations of AST and LDH were higher in horses fed a diet withoutfat, and the resultsfound to CK (Ul/L) were 118.01 (Tl); 84.24 (T2); 60.37 (T3) and 76.28 (T4). Serum leveis ofCK were significantiy smaller (P<0.05) in horses suppiemented with saturated fat, suggesting a smaller damage to the muscle fibers after the exercises.

Keywords : serum biochemical; equine athiete; suppiementation with fat.
