摘　　要：选择平均体重约9.5kg左右的三元杂交生长猪60头,随机分成3个处理组,每个处理设2个重复,每个重复10头仔猪。试验1组和试验2组在日粮中添加0.3%的小肽制剂,经过29d试验,与对照组相比平均日增重分别提高11.9%(P<0.05)和12.9%(P<0.05),料肉比降低10.6%(P<0.05)和11.06%(P<0.05),生长猪腹泻率分别降低25%(P<0.05)和20%(P<0.05)。The test picked up 60 weaning pigs about middleweight 9.5kg and randomly divide into 3 groups which each group include 2 repetitions and each repetition were made up of 10 weaning pigs. The diet of the experiment 1 group and the experiment 2 group supplement 0.3% biologically active peptides during 29 days trial. The results indicate ADG of the experiment 1 group and the experiment 2 group evidently enhance 11.9% （P〈0.05） and 12.9% （P〈0.05）, F/G evidently reduce 10.6%（P〈 0.05）andl 1.06%（P〈0.05） ,diarrhea rate evidently reduce 25%（P〈0.05）and20%（P〈0.05）.
