摘　　要：应用接续产酸型活菌制剂在仔猪１、２段日粮中进行饲养试验和仔猪粪便细菌学检查。考核１６０头０～６０日龄仔猪生产性能表明，按０．０６５亿个菌／ｋｇ体重剂量口服防治仔猪肠泻有效率１００％；与抗生素相比提高成活率２．８３％；试验期日增重提高７．１％（Ｐ＜０．０５）；饲料转化率提高４．６％（Ｐ＜０．０５）；在０～６０日龄仔猪日粮中应用活菌制剂有较为显著的经济效益。粪便涂片检查结果，饲喂益生素可使粪便总菌数有增加的趋势。Continuous Acid-Producing Microbial Ecological Agents(Probiotics) wasused in one stage and two stages diets of piglet for feeding trial and examination of feces smear.The results showed that the rate of effectiveness is 100% in the dosage of 6. 5 million compound bacteria Per kilogram body weight to Prevent and cure the bacillary diarrhoea;Compered with antibiotics,the probiotics was increased the survival rate of piglet by 2.83%,improved the average daily gain at a 7.1%(P<0.05) and the feed conversion efficiency at a 4.6%(P<0.05) in the whole rearing stage.We obtained obvious economical effect adding probiotics into the rations of 0￣60 anys piglets.The examination of feces smear indicates:probiotics has the trend which could make the to tal number of bacteria increase.
