摘要: 试验旨在探讨日粮中添加氨基酸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11匹,随机分为3组:对照组(3匹)、试验Ⅰ组(4匹)、试验Ⅱ组(4匹).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氨基酸.试验开始第20天对各组马匹进行20 km模拟比赛,赛后30 min内测定各组试验马匹的体温、脉搏、呼吸,同时采集各试验马匹血液.结果表明,试验Ⅰ、Ⅱ组焉耆马赛后0 min心率均显著低于对照组(P<0.05),赛后20 min心率、赛后5 min呼吸频率均极显著低于对照组(P<0.01);试验Ⅰ、Ⅱ组焉耆马赛后血浆中GSH-Px、T-SOD活力及GLU浓度分别比对照组高34.41%(P>0.05)、37.02%(P<0.01)、37.41%(P<0.01)和32.06%(P>0.05)、35.46%(P<0.01)、26.98%(P<0.05);试验Ⅰ、Ⅱ组焉耆马赛后血浆中MDA、LA浓度分别比对照组低38.46%(P<0.05)、17.56%(P<0.05)和38.26%(P<0.05)、13.04%(P>0.05).饲料中添加氨基酸,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;可提高运动后焉耆马的抗氧化能力,减缓焉耆马在运动期间的疲劳症状,相比而言,添加0.25%赖氨酸的效果较好.

Abstract: This test mainly studied the effects of supplemental different levels of amino acids on the performance, plasma antioxidant capacity and other metabolic index of Yanqi horse. 11 Yanqi horses were randomly divided into three groups according to performance, body weight, body measurement, age. The groups were referred to as the control group (3 horses), groupⅠ(4 horses) and group Ⅱ(4 horses). The control group was fed basal diet. Horses in the groups Ⅰ and Ⅱ were fed with diet supplemented with different levels of amino acids. 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 result showed that the heart rate value of 0 min after the racing, groups Ⅰ and Ⅱ were significantly lower than control group (P<0.05), the heart rate of 20 min after the racing and respiratory rate of 5 min after the racing, groupsⅠ and Ⅱ were highly significantly lower than the control group (P<0.01);The plasma GSH-Px, T-SOD activity and GLU concentration of groups Ⅰ and Ⅱ compared with control group respectively increased by 34.41% (P>0.05), 37.02% (P<0.01), 37.41%(P<0.01) and 32.06%(P>0.05), 35.46%(P<0.01), 26.98%(P<0.05);The plasma MDA, LA concentration of groups Ⅰ and Ⅱ compared with control group respectively decreased by 38.46%(P<0.05), 17.56%(P<0.05) and 38.26%(P<0.05), 13.04%(P>0.05). The results showed that the performance and antioxidant capacity of Yanqi horse could be improved by the basic ration added different levels of amino acids. The physiological function of Yanqi horse could be fast recovery after the racing. The symptoms of fatigue of Yanqi horse were mitigated during the race. Compared, added 0.25% lysine feed supplement was especially effective.
