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(P<0.05或P<0.01),小肠食糜黏度则极显著降低(P<0.01),而料重比、小肠食糜pH并无显著变化(P>0.05)。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 aim of this study was to investigate the effects of the combined use of Bacillus subtilis 048 (BS048) and fructooligosaccharide (FOS) on growth performance of Xueshan chickens and its mechanism. Nine hundred and eighty Xueshan chickens with similar weight were randomly divided into 2 groups with 7 replicates per group and 70 chickens per replicate. Chickens in the control group were fed a basal diet, and the others in the experimental group were fed the basal diet supplemented with 0.1% (W/W) BS048 and 0.08% (W/W) FOS. The experiment lasted for 80 days. The results showed as follows: compared with the control group, the average daily gain, average daily feed intake, duodenal digestive enzyme activities and cecal volatile fatty acid (VFA) contents in the experimental group were significantly increased (P<0.05), whereas the viscosity of intestinal chime was significantly decreased (P<0.01), and the feed to gain ratio and pH of intestinal chime had no significant changes (P>0.05). It is concluded that the combined use of BS048 and FOS not only reduce the viscosity of intestinal chyme and enhance the duodenal digestive enzyme activities to enhance intestinal digestive function, but also increase the cecal VFA contents to maintain and enhance intestinal health, thus improving the growth performance of Xueshan chickens.
