日粮中添加天蚕素抗菌肽对母猪繁殖性能的影响

Effect Cecropin on Reproductive Performance of Sows

为探讨日粮中添加天蚕素抗菌肽对母猪生产性能的影响,试验选取32头二胎经产母猪,采用单因子完全随机设计,分为试验组和对照组,试验组从母猪分娩前30 d到产后21 d添加400 kg/mg天蚕素抗菌肽,对照组按猪场正常药物保健程序进行(母猪产前产后在饲料中添加阿莫西林400 kg/mg和支原净300 kg/mg)。结果表明,对照组的活仔率、健仔率均极显著低于试验组(P<0.01);试验组初生重2、1 d体重、日增重和成活率均高于对照组,但差异不显著(P>0.05);试验组的腹泻率显著低于对照组(P<0.05)。

For discuss the effect of cecropin on reproduction performance of sows,to choose 32 sows of diplo-fetus multiparity,allotted mon-factor complete randomly design,to divide the experiment group and control group,the control group to add 400 ppm cecropin form ante parturn 30 d to postpartum 21 d,the control group was used normal meddicine heath protection process（add Amoxil 400 kg/mg and Zhiyuanjing 300 kg/mg from antepartum to postpartum of sows）.The results indicated that the survival pigline rate and healthy pigline rate of control group were very significant lower than experiment group（P〈0.01）.The born weigh in 21 d,the weight of end 21 d,daily gain and survival rate of experiment group were higher than control group（P〈0.05）,and the diarrhoea rate was significant lower than control group（P〈0.05）.
