The purpose of this experiment was to study the effects of adenosine supplementation on athletic per-formance,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 2 000 m speed race results were select-ed and randomly divided into 2 groups with 6 horses in each group(5 male and 1 female).Horses in the con-trol 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 2 000 m speed race results of Yili horses(P＞0.05).2)Compared with the control group,the adenosine supplementation signifi-cantly 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 par-tial pressure(P＞0.05).3)Compared with the control group,the adenosine supplementation significantly de-creased 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 malondial-dehyde(MDA)content on immediately at post-race of Yili horses(P＜0.05),significantly increased the plas-ma superoxide dismutase(SOD)activity on pre-race 2 h,the plasma glutathione peroxidase(GSH-Px)activi-ty 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 condi-tions,the daily supplementation of 12 g adenosine can decrease the plasma CK activity of 2 000 m speed race of Yili horses,increase the blood hemoglobin concentration and body antioxidant capacity,but has no signifi-cant effects on 2 000 m speed race results of Yili horses.[Chinese Journal of Animal Nutrition,2024,36(9):5848-5859]
