Parâmetros sanguíneos basais de cavalos submetidos à atividade aeróbica consumindo concentrados lipídicos

The feeding diets were evaluated containing low and high levels of soybean oil for horses athletes subjected to two protocols of aerobic training on the response of basal blood biochemical parameters. Four horses were used in latin square design with treatments in a 2 x 2 factorial arrangement. Treatments consisted levels of 5 and 15% oil concentrates and two aerobic training, 40' and 60' minutes. Plasmatic parameters were monitored, triglyceride (TG), total cholesterol (TC), glucose (GLU) and lactate (LAC), during basal metabolism. The TG, TC, GLU and LAC from horses at rest were not affected (P> 0.05) neither of diet and physical activity, 0.21, 3.79, 4.18, 0.93 mmol L-1, respectively. It can be concluded that offer concentrate with high content of soybean oil to athletic horses in aerobic activities can be performed without altering the blood biochemical profile of basal metabolism.
