摘　　要：试验旨在探讨日粮中添加油脂对焉耆马赛后运动性能及抗氧化能力的影响。选取运动成绩、体重、体尺、年龄相近的焉耆马9匹,随机分为3组,对照组饲喂基础日粮,试验Ⅰ、Ⅱ组分别在基础日粮中添加不同水平的豆油。试验开始第20天对各组马匹进行20km模拟比赛,赛后30min内测定各组试验马匹的体温、脉搏、呼吸,同时采集各组马匹血液。结果表明,试验Ⅰ、Ⅱ组焉耆马赛后0min心率极显著低于对照组(P<0.01),试验Ⅱ组焉耆马赛后5min呼吸频率极显著低于对照组(P<0.01);试验Ⅰ、Ⅱ组焉耆马赛后血浆中GSH-Px、T-SOD活力浓度分别比对照组高87.60%(P<0.05)、15.87%(P>0.05)和98.38%(P<0.05)、38.25%(P<0.05);试验Ⅰ、Ⅱ组焉耆马血浆中MDA、LA浓度分别比对照组低53.44%(P<0.05)、24.08%(P<0.05)和51.42%(P<0.05)、25.08%(P<0.05)。饲料中添加油脂可提高焉耆马运动性能,有利于焉耆马运动后生理机能的快速恢复,提高运动后焉耆马的抗氧化能力,相比较而言,添加5%油脂组效果较佳。This test mainly studied the effects of supplemental different levels of oil on the per- formance,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 measure- ment, age. The control group was fed with basal diet. Horses in the groups Ⅰ and Ⅱwere 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 Ⅱwas highly significantly lower than control group （P〈0.01） ,5 min after the racing. The plasma GSH-Px and T-SOD activity of groupsⅠ andⅡcompared 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 Ⅰand n 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 per- formance and antioxidant capacity of Yanqi horse could be improved by the basal diet added differ-ent 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.
