| 中文摘要:旨在研究饲粮中添加动物双歧杆菌（Bifidobacterium）对伊犁马运动成绩与心率变异性及赛后恢复的影响。选取2~3岁伊犁马骟马19匹，随机分为4组，依据其饲粮添加量依次添加0%、0.025%、0.05%、 0.1%的动物双歧杆菌（1×1011CFU/g），试验第50天测定马匹比赛成绩及比赛各阶段心率变异性(HRV)数据,分析饲粮添加双歧杆菌对伊犁马运动成绩及心率变异性的影响。结果表明：试验第50天，试验组马匹比赛用时均极显著少于对照组（P＜0.01）。正式期第50天，各组时域指标：对照组赛前Mean RR指标极显著高于赛后即刻与赛后1 h（P＜0.01），0.05%、0.1%组赛前与赛后1 h各组Mean RR指标均极显著高于赛后即刻（P＜0.01）；各组赛后即刻Mean HR均极显著高于赛前与赛后1 h（P＜0.01）。频域指标：0.1%组马匹赛后1 h其LF指标与赛前、赛后即刻相比显著降低（P＜0.05），赛前、赛后1 h马匹HF指标显著高于赛后即刻（P＜0.05）；0.1%组赛前LF指标显著高于对照组（P＜0.05）。非线性指标：0.05%组、0.1%组赛后1 h全部R-R间距的标准差（X）（SD2）均显著高于对照组（P＜0.05），各双歧杆菌添加组赛后即刻SD2均极显著高于对照组（P＜0.01）。综上可见，饲粮中添加动物双歧杆菌可提高伊犁马运动成绩，改善赛后心率变异性，提高赛后恢复速度，缓解赛后应激，对伊犁马运动性能及机体健康有一定的积极影响。 |

| Abstract:This study investigates the effects of Bifidobacterium on exercise performance, heart rate variability (HRV) and post-race recovery in Yili horses. Nineteen Yili horses, aged 2-3 years,were randomly assigned to four groups and fed diets supplemented with 0%, 0.025%, 0.05% and 0.1% of Bifidobacteria (1×1011CFU/g).On the 50th day of the experiment, race performance and HRV data were collected to assess effects of the supplementation. The results showed that on the 50th day of the experiment, horses in the supplemented groups completed the race significantly faster than those in the control group (P<0.01). Before the race, the time-domain Mean RR index in the control group was significantly higher than immediately after and 1 hour post-race (P<0.01). In the 0.05% and 0.1% groups, Mean RR before and 1 hour post-race was also significantly higher than immediately after the race (P<0.01). Mean HR in all groups was significantly higher immediately post-race compared to 1 hour pre- and post-race (P<0.01).For frequency domain index, the LF index of the 0.1% group was significantly lower 1 hour after the race compared to pre-race and immediately post-race. Conversely,the HF index was significantly higher before the race and 1 hour after the race than immediately after the race. The pre-race LF index of the 0.1 group was also significantly higher than that of the control group (P<0.05). In terms of non-linear index, the SD2 (standard deviation of all R-R intervals) in the 0.05% and 0.1% groups was significantly higher than that in the control group (P<0.05), with the SD2 of all supplemented groups being significantly higher immediately post-race (P<0.01).In conclusion, dietary Bifidobacterium supplementation improves exercise performance, enhances the HRV, accelerates recovery,reduces post-race stress, and has a certain positive effect on overall athletic performance and health of the Yili horses. |
