Abstract:To investigate the effects of Chinese herbal additives on growth performance and blood biochemical indexes of Barmei meat sheep,100 6monthold meat sheep with similar body weight and good body condition were randomly divided into 2 groups (experimental group and control group) with 5 replicates per group and 10 sheep per replicate.The experimental group was fed with 0.5% Chinese herbal additives in the diet for 30 days,and the control group only fed the basic diet.Growth performance and blood biochemical indexes were measured after feeding for 30 days.The results showed as follows:Compared with the control group,the final weight and average daily gain feed to meat ratio of experimental group increased by 2.79% and 18.18%,respectively,and the feed to meat ratio decreased by 14.28%.The average daily gain and ratio of feed to meat were significantly different from control group (P<0.05).Total protein (TP) and globulin (GLO) were increased by 14.69% and 34.66%,respectively.TP and GLO were significantly higher than control group (P<0.05),aspartate transferase (AST),alanine aminotransferase (ALT) and creatine kinase (CK) were decreased by 28.29%,24.14% and 29.57,respectively.AST,ALT and CK were significantly lower than those in control group (P<0.05).Studies have shown that adding 0.5% of Chinese herbal additives to the diet can effectively improve the production performance of mutton sheep,and can play a positive and effective role in blood biochemical indexes.
