摘要
为了研究在饲料中添加水溶性微生物制剂(1×105CFU/m L乳酸菌+1×104CFU/m L酪酸菌)按不同的方案进行饲喂白羽肉鸡后,对其生长性能及肠道微生物区系的影响.试验选择1日龄优质白羽肉鸡400羽,预饲7 d后随机分成4组饲养,各组日粮中均不添加抗生素.对照组为基础日粮,试验1组为用1 d停2 d,试验2组为用3 d停3 d,试验3组为用3 d停7 d.试验全期的生产性能结果表明,添加乳酸杆菌和芽孢杆菌微生态制剂组可不同程度地改善肉鸡日粮的利用率,提高日龄的均重、降低死亡率等,在饲料中有一定应用前景,其中用3 d停3 d的方案综合效果最为明显.
This paper investigated the effects of three different operational schemes of water soluble probiotics on growth performance and intestinal microflora of broilers. The study used one-day-old high quality broiler 400 feathers which were divided into three groups after 7 day pre feeding. The results indicated the addition of Lactobacillus and Bacillus probiotics could improve the utilization rate of broiler diets in different degrees,increase the average weight of broilers and reduce the mortality rate of them. It showed the method has a certain application prospect in feed.
