We watched the fat, and his effect as an energy source. But we watched also the influence of fat additions and their potential impact on the metabolic conversion of other received nutrients. For the addition of fat, we used evening primrose oil - EPO by which can be assumed to influence the metabolism in the body of sport horses. The 16 weeks experiment was performed on clinically healthy racehorses. All the horses were enrolled in a regular training program. Addition of EPO was 150 g per day. The blood samples were collected every 4 weeks during the experiment. There were analysed a selected biochemical parameters. Values of glucose and cholesterol were after administration of EPO significantly higher. Keywords : evening primrose oil, sport horses, glucose, TAG, cholesterol References ART, T. and LEKEUX, P.
