| 摘 要： | 试验旨在探讨日粮中添加硫辛酸对焉耆马赛后运动性能、血浆抗氧化能力及代谢指标的影响.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,分别为: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12.5、25 g/(d·匹)的硫辛酸.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,同时采集各试验组马匹血液.结果表明,无论是赛后0 min还是赛后20 min,试验Ⅰ、Ⅱ组测得的心率均极显著低于对照组(P <0.01);试验Ⅰ组焉耆马血浆中GSH-Px活力比对照组高44.30%(P <0.05);试验Ⅰ、Ⅱ组焉耆马血浆中SOD活力、T-AOC大小分别比对照组高42.33%(P <0.01)、44.72%(P <0.01)和77.41%(P >0.05)、68.62%(P >0.05);试验Ⅰ、Ⅱ组焉耆马血浆中MDA浓度比对照组低41.09%(P <0.05)、23.48%(P >0.05);试验Ⅰ、Ⅱ组焉耆马血浆中NEFA浓度与对照组相比有升高的趋势(P >0.05).在饲料中添加硫辛酸,可提高焉耆马运动性能,有利于焉耆马运动后生理指标的快速恢复,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12.5 g/(d·匹)硫辛酸组效果较佳. |

| Abstract: | This study was conducted to the effects of supplemental different levels of lipoic acid 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 and 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 groupsⅠ and Ⅱ were fed with diet supplemented with different levels of lipoic acid.All horses were participated in 20 km racing,on the 20th day.The temperature,the heart rate,the 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 the groups Ⅰ and Ⅱ were highly significant lower than the control group (P <0.01),0 and 20 min after the racing.Compared with that of the control group,the plasma GSH-Px activity of the group Ⅰincreased by 44.30% (P <0.05);In addition,the plasma SOD,T-AOC activity of the groups Ⅰ and Ⅱ respectively increased by 42.33% (P <0.01),44.72% (P <0.01) and 77.41% (P >0.05),68.62% (P >0.05);The plasma MDA concentration of the groups Ⅰ and Ⅱ decreased by 41.09% (P <0.05)and 23.48% (P >0.05);and there was a tendency that the plasma NEFA concentration of the groups Ⅰ and Ⅱ were higher than that of the control group (P >0.05).The results showed that the performance and plasma antioxidant capacity of Yanqi horse could be improved by the basal diet added different levels of lipoic acid.Also the physiological function of Yanqi horse could be fast recovery after the racing.Moreover,the symptoms of fatigue of Yanqi horse were mitigated during the racing.In contrast,the effect was better by the addition of lipoic acid in diets of 12.5 g/(d·horse). |
