Abstract:

To investigate the effects of adding Sophora alopecuroides to high grain diet on growth performance and serum biochemical indexes of Dumeng lambs, a total of 32 healthy Dumont lambs weighing about (25.7±2.17)kg were randomly divided into 4 groups with 8 replicates in each group. The control group was fed with basal diet, and the T1,T2 and T3 groups were fed with 0.1%,0.3% and 0.5% Sophora alopecuroides, respectively.The pre-test period was 15 days, and the positive test period was 60 days.The results showed as follows: On the 0-30th day of the experiment, the stage daily gain (SDG) of T1 group was significantly (P<0.05) higher than that of T3 group. From 30th to 60th day, the stage daily feed intake (SDFI) of T2 group was significantly (P<0.05) higher than that of control group. Compared with the control group, the concentration of aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in T1 group increased significantly, while the concentration of direct bilirubin (DBIL) decreased significantly (P<0.05). On the 30th day, the contents of alkaline phosphatase (ALP) and albumin (ALB) in T2 group increased significantly (P<0.05), and on the 60th day, the contents of total protein (TP) and globulin (GLO) increased significantly (P<0.05 or P<0.01). It was concluded that adding proper amount of Sophora alopecuroides in high grain diet could promote the growth performance of lambs,improve the blood biochemical state of sheep, and the effect of adding 0.1%-0.3% Sophora alopecuroides was better.
