Effects of Adenosine Supplementation on Athletic Performance,Blood Oxygen Carrying Capacity and Antioxidant Capacity of Yili Horses
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]
