Abstract: The study was aimed to investigate the effects of feeding pregnant ewes with bamboo vinegar power on growth performance,blood physiological and biochemical indexes,antioxidant and immune ability of lambs.A total of 50 healthy,primiparous pregnant ewes at about 120 d pregnant age were chosen and randomly divided into 2 groups.The control group was fed basic diet and the experimental group was fed basic diet with 2% of bamboo vinegar power.Feeding period was 3 weeks (1 week for preliminary feeding).After delivery,the growth performance,blood physiological and biochemical indexes,antioxidant and immune ability of twenty three-week-old lambs with similar delivery date (1-4 d) were detected.The results showed as follows:The difference of BW and ADG between the two groups were not significant (P>0.05),but the ADG of experimental group was increased by 4.74% compared to control group.Compared with the control group,blood leukocyte,erythrocyte,platelet and hemoglobin contents of experimental group had no significant change (P>0.05),but GOT activity decreased significantly (P<0.05).TP,ALB,GLB and A/G increased in a certain extent,while the levels of TC,MDA,SOD activity and T-AOC had an decreased trend (P>0.05).Compared with the control group,there was an increased trend in IgA,IgM and IgG of experimental group,but the differences were all not significant (P>0.05).In conclusion,supplementing bamboo vinegar power in diets for pregnant ewes could improve ADG,increase serum TP,ALB,GLB,IgA,IgM and IgG contents in a certain degree.
