Effects of Eucommia ulmoides leaves extract on growth performance,serum biochemical and antioxidant indexes of hu sheep
To analyze the effects of Eucommia ulmoides leaves extract on growth performance,serum biochemical and antioxidant indicators of Hu sheep.Select 80 fattening Hu sheep weighing around 27.53kg and in good health,and randomly divide them into 4 groups,with 4 replicates in each group,with 5 sheep in each replicate.The control group of Hu sheep was fed a basic diet in accordance with the"Nutrient Requirements for Meat Sheep(NY/T816-2021)"standard,while the other three groups of Hu sheep were fed an experimental diet with a basic diet of+500,1000,and 1500 g/t of Eucommia ulmoides leaves extract.The pre trial period is 7 days,and the trial period is 60 days.The results showed that,(1)Compared with the control group,the basal diet+1000 g/t of Eucommia ulmoides leaves extract significantly increased the final weight of Hu sheep by 8.56%(P＜0.05);Compared with the control group,the basal diet with 1000 and 1500 g/t Eucommia ulmoides leaves extract significantly increased the average daily gain of Hu sheep by 29.25%and 25.00%(P＜0.05),and the average daily feed intake of Hu sheep was significantly increased by 22.33%and 20.94%(P＜0.05).(2)Compared with the control group,the basal diet+500,1000,and 1500 g/t of Eucommia ulmoides leaves extract significantly increased the total protein and albumin content in the serum of Hu sheep(P＜0.05),while the basal diet+1000,1500 g/t of Eucommia ulmoides leaves extract significantly reduced the low density lipoprotein content in the serum of Hu sheep(P＜0.05).(3)Compared with the control group,the basal diet of+500,1000,and 1500 g/t Eucommia ulmoides leaves extract significantly increased the T-AOC and GSH-Px activities in the serum of Hu sheep(P＜0.05),and significantly reduced the MDA content in the serum(P＜0.05).The basal diet of+1000,1500 g/t Eucommia ulmoides leaves extract significantly increased the CAT and SOD activities in the serum of Hu sheep(P＜0.05).Conclusion:Eucommia ulmoides leaves extract can improve the growth performance of Hu sheep,improve serum biochemical and antioxidant indicators,and the appropriate dosage of Eucommia ulmoides leaves extract in the basic diet is 1000 g/t.
