选择杜×长×大三元杂交哺乳仔猪90头,来源于吉林经开区吉特种猪场。随机分为3组,即微生态制剂组、抗生素组和对照组。测定试验期各试验猪群平均采食量,便秘发生率,日增重,腹泻率,料肉比。结果表明：添加微生态制剂组在仔猪增重方面分别比抗生素组高7.89%,比对照组高10.81%,差异显著（P〈0.05）;添加微生态制剂组比抗生素组腹泻率降低了6.7%,比对照组降低了36.7%,试验一组与对照组相比差异极显著（P〈0.01）,并且显著地降低了仔猪死亡率（P〈0.05）。%Ninety suckling piglet from three way mating Duroc×Landrace×Large White were divided randomly into microbial ecological agents group,antibiotics group and control group.Determination of average amount of foraging,incidence rate of constipation,daytime weight,diarrhea ratio and feed meat ratio.The results showed that piglet daytime weight were obviously higher as compared with control group and antibiotics group(P 0.05).diarrhea ratio were obviously lower as compared with control group and antibiotics group,experiment one group were obviously lower as compared with control group(P 0.01),and death rate of piglet was notably cut down(P 0.05).
