【摘要】：本试验旨在研究枯草芽孢杆菌048(BS048)和果寡糖(FOS)联用对雪山草鸡生长性能的影响及其机理。试验选用980只体重相近的1日龄雪山草鸡(公),随机分为2组,每组7个重复,每个重复70只鸡。对照组饲喂基础饲粮,试验组在基础饲粮中添加0.1%(W/W)BS048和0.08%(W/W)FOS。试验期为80 d。结果表明:与对照组相比,试验组雪山草鸡的平均日增重(ADG)、平均日采食量(ADFI)、空肠消化酶活性和盲肠挥发性脂肪酸(VFA)含量均显著或极显著提高(P0.05或P0.01),小肠食糜黏度则极显著降低(P0.01),而料重比、小肠食糜p H并无显著变化(P0.05)。由此可见,BS048和FOS联用,不仅能够降低小肠食糜黏度并提高空肠消化酶活性,增强肠道的消化功能,而且可以促进盲肠VFA的产生,维持并改善肠道健康状况,从而提高雪山草鸡生长性能。
[Abstract]:The purpose of this experiment was to study the effect of Bacillus subtilis 048BS048) and fructose oligosaccharide (FOS) on the growth performance and its mechanism of Xueshan Chicken. A total of 980 1-day-old Xueshancao chickens of similar body weight were randomly divided into 2 groups with 7 replicates in each group and 70 chickens in each replica. The control group was fed with basic diet, the experimental group was fed with 0.1%(W/W)BS048 and 0.08% W / WN FOSs. The experimental period is 80 days. The results showed that: compared with the control group, In the test group, the average daily gain (ADG), average daily intake (ADFI), jejunal digestive enzyme activity and the content of VFAs in the caecum of Xueshan grass chicks were significantly or extremely increased, while the viscosity of small intestine chyme decreased significantly, while the feed / weight ratio was significantly decreased. There was no significant change in small intestinal digesta pH (P 0.05). It can be seen that BS048 combined with FOS can not only reduce the intestinal chyme viscosity and increase the activity of jejunal digestive enzymes, but also promote the production of VFA in the caecum and maintain and improve the intestinal health. So as to improve the growth performance of Xueshan grass chicken.
