枯草芽孢杆菌-菊糖合生元对断奶仔猪生长性能及体液免疫功能的影响
Effects of Bacillus subtilis-Dahlin Synbiotics on Growth Performance and Humoral Immunity in Weaner Piglets
摘要
Abstract
This experiment was conducted to study the effects of Bacillus subtilis-dahlin synbiotics on growth performance and humoral immunity in weaner piglets. Seventy-two 21-day-old weaner piglets ( Duroc x Landrace x Yorkshire) with an average body weight of (4. 25 ±0. 71) kg were randomly allocated into 4 groups with 3 replicates in each group and 6 piglets in each replicate. Piglets in the four groups were gavaged with the following solutions; nutrient medium (CG) , nutrient medium +3.5 mg/mL dahlin (DG) , nutrient medium + 1. 25 x 108 CFU/mL Bacillus subtilis (BG) , nutrient medium +3.5 mg/mL' dahlin + 1. 25 x 108 CFU/mL Bacillus subtilis (DBG) , respectively. The gavage dose was 16 mL/d. The duration of the experiment was 14 d. The results showed as follows; 1) the average daily gain of BG and DBG was significantly higher than that of CG and DG (P < 0. 05). Simultaneously, the feed/gain and diarrhea rate of BG and DBG were significantly decreased compared with CG and DG (P <0. 05). 2) The serum IgG content of DG, BG and DBG was significantly higher than that of CG (P <0. 05) , and compared with DG and BG, the serum IgG content of DBG was significantly increased (P < 0. 05). The serum IgA content of BG and DBG was significantly higher than that of CG and DG (P <0. 05) , meanwhile, the contents of C3 and C4 of DBG were significantly higher than those of CG (P <0. 05). In conclusion, the Bacillus subtilis-dahftn synbiotics enhance the growth performance and humoral immune functions in weaner piglets. [ Chinese Journal of Animal Nutrition, 2012, 24(2) =280-284]关键词
