摘　　要：选择28 d 龄断奶仔猪64头,随机分为2组,每组设4个重复,每次重复均为8头(公母对半),进行为期6周的饲养试验,研究基础日粮中添加500mg/kg 乳酸芽孢杆菌制剂取代抗生素对仔猪生产性能的影响.结果表明:与对照组相比,试验组仔猪日增重提高9.78%(P<0.05),料肉比降低0.14(P<0.05),腹泻率降低2.81%,成活率提高3.1%.The experiment was conducted to study the effects of Lactobacillus sporogenes on productive performance of piglets. Sixty four 28 - day - old weanling piglets were assigned to two groups randomly. There are four repeat in every groups, and with eight piglets per repeat （haft in male）. The experiments go on 42 days. The results showed： Compared with control group, 500mg/kg Lactobacillus sporogenes increased daily gain by 9.78%（P 〈 0.05）, and reduced feed / gain ratio by 0.14（ P 〈 0.05）, and decreased dimThea by 2.81%, improved survive rate by 3.1%.
