摘　　要：本试验旨在探究补喂腺苷对伊犁马运动性能、血液载氧能力和抗氧化能力的影响。选取年龄为2岁、经过严格训练、2000 m速度赛成绩相近的伊犁马12匹,平均体重为(389.96±34.22)kg,随机分为2组,每组6匹(5公1母)。对照组马匹每天饲喂精料补充料6 kg,干牧草8 kg;试验组马匹在对照组基础上每天补喂12 g的腺苷。试验期35 d。结果表明:1)补喂腺苷对伊犁马2000 m速度赛成绩无显著影响(P>0.05)。2)与对照组相比,补喂腺苷显著提高了伊犁马赛后即刻血液血红蛋白浓度(P<0.05),对血液红细胞数目、氧分压和二氧化碳分压无显著影响(P>0.05)。3)与对照组相比,补喂腺苷显著降低了伊犁马赛前2 h和赛后即刻血浆肌酸激酶(CK)活性(P<0.05),对血浆乳酸脱氢酶(LDH)活性无显著影响(P>0.05)。4)与对照组相比,补喂腺苷显著降低了伊犁马赛后即刻血浆丙二醛(MDA)含量(P<0.05),显著提高了赛前2 h血浆超氧化物歧化酶(SOD)活性、赛前2 h和赛后即刻血浆谷胱甘肽过氧化物酶(GSH-Px)活性及赛前2 h、赛后即刻和赛后2 h血浆总抗氧化能力(T-AOC)(P<0.05)。由此可见,在本试验条件下,每天补喂12 g腺苷降低了2000 m速度赛伊犁马血浆CK活性,提高了血液血红蛋白浓度以及机体抗氧化能力,但对伊犁马2000 m速度赛成绩没有影响。The purpose of this experiment was to study the effects of adenosine supplementation on athletic performance,blood oxygen carrying capacity and antioxidant capacity of Yili horses.Twelve 2-year-old strictly trained Yili horses with average body weight of(384.9±33.98)kg and 2000 m speed race results were selected and randomly divided into 2 groups with 6 horses in each group(5 male and 1 female).Horses in the control group were fed with 6 kg concentrate supplement and 8 kg dry forage per day,and others in experimental group were fed with 12 g adenosine per day based on the control group.The experiment lasted for 35 days.The results showed as follows:1)the adenosine supplementation had no significant effects on 2000 m speed race results of Yili horses(P>0.05).2)Compared with the control group,the adenosine supplementation significantly increased the blood hemoglobin concentration on the Immediately at post-race of Yili horses(P<0.05),but had no significant effects on the blood red blood cell count,oxygen partial pressure and carbon dioxide partial pressure(P>0.05).3)Compared with the control group,the adenosine supplementation significantly decreased the plasma creatine kinase(CK)activity on pre-race 2 h and immediately at post-race of Yili horses(P<0.05),but had no significant effect on the plasma lactate dehydrogenase(LDH)activity(P>0.05).4)Compared with the control group,the adenosine supplementation significantly decreased the plasma malondialdehyde(MDA)content on immediately at post-race of Yili horses(P<0.05),significantly increased the plasma superoxide dismutase(SOD)activity on pre-race 2 h,the plasma glutathione peroxidase(GSH-Px)activity on pre-race 2 h and immediately at post-race and the plasma total antioxidant capacity(T-AOC)on pre-race 2 h,immediately at post-race and post-race 2 h(P<0.05).In conclusion,under these experimental conditions,the daily supplementation of 12 g adenosine can decrease the plasma CK activity of 2000 m speed race of Yili horses,increase the blood hemoglobin concentration and
