Abstract: This test mainly studied the effects of supplemental different levels of oil on the performance, plasma antioxidant capacity and other metabolic index of Yanqi horse.9 Yanqi horses were randomly divided into three groups according to performance, body weight, body measurement, age.The control group was fed with basal diet.Horses in the groups Ⅰ and Ⅱ were fed with diet supplemented with 2.5% and 5% of oil.All horses were participated in 20 km racing, on the 20th day.Temperature, heart rate, respiratory rate of all horses were measured, 30 min after the racing.Simultaneously, blood samples were collected from the jugular vein.The results showed that the heart rate value of groups Ⅰ and Ⅱ were highly significant lower than control group (P<0.01), 0 min after the racing.The group Ⅱ was highly significantly lower than control group (P<0.01), 5 min after the racing.The plasma GSH-Px and T-SOD activity of groups Ⅰ and Ⅱ compared with the control group respectively increased by 87.60%(P<0.05), 15.87%(P>0.05) and 98.38%(P<0.05), 38.25%(P<0.05);The plasma MDA and LA concentration of groups Ⅰ and Ⅱ compared with the control group respectively decreased by 53.44% (P<0.05), 24.08%(P<0.05) and 51.42% (P<0.05), 25.08%(P<0.05).In conclusion, the performance and antioxidant capacity of Yanqi horse could be improved by the basal diet added different levels of oil.The physiological function of Yanqi horse could be fast recovery after the racing.Compared, added 5% oil feed supplement was especially effective.
