Abstract: 【Objective】 The purpose of this experiment was to study the effects of formononetin on the performance,blood gas and antioxidant indexes of Yili horses in 1 000 m race,so as to provide references for the research and development of effective nutritional supplements in the training process of Yili horses.【Method】 Twelve male Yili horses with average body weight (411 kg±29 kg),average age (2.0±0.50 years old),similar performance (135.24 s±15.75 s) in the 1 000 m race and good health were selected as the research subjects and randomly divided into control group and experimental group,with six horses in each group.Under the same conditions of feeding management,dietary nutrition level and exercise training,each horse in the experimental group was fed with formononetin 8 g per day for a supplementary feeding trial of 30 days.A 1 000 m race was held on the 30th day of the test,race results were recorded and blood samples were collected via a jugular vein immediately after the race,the electrolyte level,acid-base balance and blood gas indexes were measured by blood gas analyzer,and the antioxidant indexes were measured by kit.【Result】 The supplementary feeding of formononetin could significantly shorten the race time of the 1 000 m race of Yili horse (P<0.05).There was no significant effect on plasma electrolyte level,acid-base balance and blood gas-related indicators (P>0.05).In the aspect of plasma antioxidant indexes,the supplemental formononetin could significantly increase the superoxide dismutase,catalase and total antioxidant capacity in the plasma of horses after the race,which were increased by 11.12% (P<0.05),8.45% (P<0.05) and 32.70% (P<0.05),respectively as compared with those in control group.The contents of glutathione peroxidase and malondialdehyde in the experimental group were decreased by 1.56% and 11.32% respectively as compared with those in control group,but there was no significant difference (P>0.05).【Conclusion】 Under the conditions of this experiment,the supplementary feeding of formononetin to Yili horse could significantly improve the performance of the 1 000 m race,enhance the antioxidant capacity.
