摘　　要：本试验旨在研究保育日粮中添加0.3%抗菌肽替代0.2%氧化锌对仔猪腹泻率、生产性能及血清猪瘟抗体的影响。选用35日龄平均体重无显著差异的三元仔猪48头,随机分为2组,每组3个重复,每个重复8头仔猪(公母各半),试验期为24 d。期间观察仔猪的生长及腹泻情况,59日龄时每个重复随机选择1头健康仔猪,共6头进行前腔静脉空腹采血并制备血清,采用酶联免疫吸附测定法(ELISA)检测猪瘟抗体水平。试验表明,添加0.3%抗菌肽替代0.2%氧化锌能显著降低仔猪腹泻率及饲料增重比(P<0.05),显著提高仔猪日增重(P<0.05),对血清猪瘟抗体水平也有一定的改善作用(P>0.05)。The experiment was conducted to study effects of adding antibacterial peptide instead of ZnO on growth performance, diarrhea incidence and antibody level against CSFV of weanling piglets.48 weanling piglets of thirty-five days old （DuroexLandracexYorkshire） were selected according to their weight and sex, and randomly divided into two groups for three replicates of eight pigs each.The experiment lasted for twenty-four days and the antibody level against CSFV was determined by ELISA at the piglets of fifty-nine day old.The first group was fed with ZnO, and the treatment group was fed with antibacterial peptide.ADG and the antibody level against CSFV of treatment group increased significanfly（P 〈 0.05）, F/G and diarrhea incidence decreased significantly.
