Abstract

This experiment was conducted to study the effects of probiotic preparations on growth performance and serum biochemical indexes in housed lambs. One hundred 4-month-old goats were randomly allocated to 5 groups with 4 replicates per group and 5 goats per replicate. The control group was fed a basal diet, the other four groups were supplemented with 0.1%, 0.2%, 0.4%, and 0.8% probiotic preparations in the basal diet. The trial period was 40 days, of which the pre-test period was 10 days and the trial period was 30 days. The results show as follows:1) compared with the control group, the addition of 0.2% probiotic preparations in the diet significantly increased the average daily gain in housed lambs (P<0.05). The addition of 0.2%, 0.4% and 0.8% probiotic preparations in the diet significantly reduced the feed/gain in housed lambs (P<0.05). 2) Compared with the control group, the addition of 0.2%, 0.4% and 0.8% probiotic preparations in the diet significantly increased serum total protein and globulin contents in housed lambs (P<0.05). 3) Compared with the control group, the addition of 0.2%, 0.4% and 0.8% probiotic preparations to the diet significantly increased the serum total superoxide dismutase activity in housed lambs (P<0.05). The above results show that the addition of compound probiotic preparations enhance the growth performance, and improve the body immunity and antioxidant function of housed lambs.
