Resumo
Vegetable oil supplementation has often been used in high performance horse feeding. The aim of the current study is to evaluate lipidic metabolism during the low intensity tests in fat-supplemented horses. Twelve untrained Arabian horses were divided into two groups, in which each group was supplemented with soybean oil or rice bran oil for a period of six weeks. Before and after this period they were submitted to low intensity test (TLD) on a high-speed treadmill, and blood samples were taken before, during and after exercise. In TLD there was an increase in serum free fat acids (AGL) levels and decrease in serum triacylglycerol levels in fat-supplemented horses in both groups (P<0,05). No significant difference was observed in HDL values in TLD after supplementation. There was an increase in energy availability during low intensity exercise by increasing AGL and the maintenance of the lactate levels in fat-supplemented horses. Changes in the lipidic metabolism provided by vegetable oil supplementation are favorable for performance during TLD.
