Effects of Fermented Soybean Meal on Growth Performance, Serum Biochemical Indices, Mucosal Immune Function and Microorganism in Yellow-Feathered Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of fermented soybean meal on growth performance , serum biochemical indices, mucosal immune function and microorganism in yellow-feathered broilers. A total of 250 one-day-old yellow-feathered broilers were randomly divided into five groups, and each group included five replicates (10 broilers per replicate). Control group (group Ⅰ ) was fed a basal diet. Group Ⅱ was fed the basal diet supplemented with 15% zinc bacitracin 200 mg/kg and 10% colistin sulfate 60 mg/kg. The treatment groups (groups Ⅲ, Ⅳ, Ⅴ ) were fed the basal diet replaced some of common soybean meal with 3% , 6% and 9% fermented soybean meal,respectively. The experiment lasted for 28 days. The results showed as follows: 1) compared with group Ⅰ , the body weight gain of groups Ⅳ and Ⅴ was significantly increased by 3. 87% and 4. 38% (P <0. 05) , respectively; the feed/gain of groups Ⅳ and Ⅴ was significantly reduced by 4. 75% (P >0. 05) and 5. 71% (P <0. 05) , respectively; the rate of survival of group Ⅴ was significantly increased by 6. 38% (P <0. 01). 2) The activity of alkaline phosphatase in serum of groups Ⅱ and Ⅴ was significantly higher than that of group Ⅰ (P <0. 05) , uric acid content in serum of group Ⅴ was significantly lower than that of group Ⅰ(P <0. 05) , and the other groups were no significant differences (P>0.05). 3) Compared with group Ⅰ , duodenum villus height of groups Ⅱ,ⅢⅣand Ⅴ was significantly higher than that of group Ⅰ(P <0.01), and group V was the highest. The number of mast cells of group Ⅴ was significantly decreased compared with group Ⅰ (P <0.01). The number of secretory immunoglobulin A (slgA) positive cells of groups Ⅱ , Ⅲ, Ⅳ and Ⅴ was significantly increased compared with group Ⅰ (P <0. 01) , and group Ⅴ was the highest in all. 4) The number of Escherichia coli of groups Ⅱ and Ⅴ was significantly lower than that of groups Ⅰ , Ⅲ and Ⅳ (P <0. 05) , and the number of Lactoba-cillus of group V was significantly increased compared with group Ⅰ ( P <0. 05). It is concluded that fermented soybean meal can improve the body weight gain and the activity of alkaline phosphatase in serum, decrease feed/gain and uric acid content in serum, increase duodenal villus height, make the number of mast cells and slgA-positive cells stable and intestinal micro environment better, reduce the number of Escherichia coli in cecum, and increase the number of Lactobacillus in yellow-feathered broilers and the best replacement rate in prior period is 9% .关键词
