摘要
将500只1日龄的肉仔鸡随机分成5组,每组5个重复,每重复20只鸡,1个对照组和4个试验组,试验期6周,考察保加利亚乳杆菌及其代谢产物对肉仔鸡生长性能的影响。结果表明,相比对照组及其他试验组,日粮中添加保加利亚乳杆菌及其代谢产物能够提高肉仔鸡后期日增重,有提高成活率和降低腹泻率的趋势,但对肉仔鸡新城疫免疫效果影响不大。
Five hundred healthy Avian broilers of one day were randomly divided into five groups, each included five replicates of twenty birds each. The birds were given a basal corn-soybean meal diet with Lactobacillus bulgaricus and its metabolites of different concentration for a period of six weeks. The result showed that adding Lactobacillus bulgaricus and its metabolites improved livability and daily gain of broilers, decreased diarrhea ratio than the control, but it didn＇t showed any obvious difference on the HI antibody level of ND
