Abstract

This experiment was conducted to investigate the effects of complex-probiotic-preparation on fattening performance and serum biochemical indexes of captive goats. Eighty healthy Nubian female goats of similar age and body weight were selected and randomly divided into 5 groups with 4 replicates in each group and 4 goats in each replicate. Goats in 5 groups were fed basal diets supplemented with 0 (control group), 0.1%, 0.2%, 0.4% and 0.8% complex-probiotic-preparation (it was composed of Lactobacillus plantarum and yeast, and the viable numbers of them were 2.0×10⁶ and 1.0×10⁶ CFU/mL, respectively), respectively. The pre-feeding period of 7 days and the trial period was 60 days. The results showed as follows:compared with the control group, the average daily gain (ADG) in 0.2%, 0.4% and 0.8% probiotics groups were increased by 20.00%, 22.46% and 15.79% (P>0.05), respectively, and the feed/gain was decreased by 17.65%, 20.68% and 15.36% (P>0.05), respectively; the contents of serum total protein and globulin in 0.2%, 0.4% and 0.8% probiotics groups were significantly increased (P<0.05); and also, in the 0.4% probiotics group, the serum total antioxidant capacity and total superoxide dismutase activity were significantly increased (P<0.05), and the serum malondialdehyde (MDA) content was significantly decreased (P<0.05); in addition, the contents of serum immunoglobulin G (IgG), immunoglobulin A (IgA) and immunoglobulin M (IgM) in 0.4% probiotic group were significantly increased (P<0.05). The results indicate that adding 0.4% complex-probiotic-preparation to the diet can increase the contents of serum immunoglobulins, improve the antioxidative function, and has the trend of improving the fattening performance of captive goats.

Key words： complex-probiotic-preparation; captive goats; fattening performance; serum biochemical indexes; serum antioxidant indexes; immunoglobulin
