抗菌肽对仔猪生长性能及降低腹泻率的影响

为了研究抗菌肽制剂对仔猪生产性能和健康水平的影响,本试验选取316头仔猪作为研究对象,分为对照组和试验组,试验组教槽料中添加抗菌肽制剂1 kg/t,保育料中添加抗菌肽制剂500 g/t。试验结果：试验组仔猪的末重比对照组高1.71 kg,日增重比对照组高0.07 kg,料肉比比对照组降低0.10,腹泻头数明显低于对照组,少43头,腹泻率明显低于对照组,低23.7%,并且两组之间差异显著（P〈0.05）。结果表明：抗菌肽制剂作为饲料添加剂,,为可以改善仔猪的生产性能,明显的降低仔猪的腹泻头数和腹泻率。

Effects of .Antimicrobial Peptide on Growth Performance and Reduce Diarrhea Rates of Piglets

In order to study the effect of antimicrobial peptide on growth performance and health of piglets,316 piglets were randomly allotted to two treatments, control group and the test group respectively. The test group added antimicrobial peptides l kg/t to creep feed, and added antimicrobial peptides 500g/t to conservation feed. The results was that final weight of experimental group piglets is 1.71kg higher than control group; average daily gain is 0.07kg higher than control group; feed conversion is 0.10 lower than the control group; diarrhea piglets was significantly lower than the control group, less 43 head, diarrhea rates was significantly lower than the control group, 23.7% lower, and the difference between the two groups was significantly （P 〈 0.05）. The results showed that antimicrobial peptide can improve growth performance of piglet, and can reducing head count of diarrhea and diarrhea rates of piglets significantly as feed additives.
