摘　　要：试验旨在研究不同添加水平的抗菌肽对断奶仔猪生长性能、腹泻率和猪瘟疫苗免疫效果的影响。90头断奶仔猪随机分成未添加组、添加Ⅰ组、添加Ⅱ组,分别在基础日粮中添加0、0.05%、0.10%抗菌肽,试验期30 d。结果显示,与未添加组相比,添加Ⅰ组、添加Ⅱ组的断奶仔猪末重、平均日采食量、平均日增重、猪瘟抗体阻断率以及血清免疫球蛋白A(IgA)、免疫球蛋白G(IgG)、白细胞介素-2(IL-2)的含量均显著升高(P<0.05),料重比、腹泻率均显著降低(P<0.05)。与添加Ⅰ组相比,添加Ⅱ组断奶仔猪的平均日采食量、平均日增重、猪瘟抗体阻断率及血清IgG、IL-2的含量均显著升高(P<0.05),腹泻率显著降低(P<0.05)。研究表明,在日粮中添加抗菌肽可使断奶仔猪的生长性能、腹泻率及猪瘟疫苗免疫效果得到改善,添加剂量为0.10%时改善效果最明显。The experiment was conducted to investigate the effect of different supplemental levels of antimicrobial peptides on growth performance,diarrhea rate and immunization effect of classical swine fever vaccine in weaned piglets.90 weaned piglets were randomly divided into three groups,the non supplemented group,the supplemented groupⅠand the supplemented groupⅡwere supplemented with 0,0.05%and 0.10%antimicrobial peptides in the basal diet,the experimental period was 30 d.The results showed that compared with non supplemented group,the final weight,average daily feed intake,average daily gain,CSFV antibody blocking rate and content of IgA,IgG and IL-2 in serum of supplemented groupⅠand supplemented groupⅡwas content significantly increased(P<0.05),and the feed weight ratio and diarrhea rate significantly decreased(P<0.05).Compared with supplemented groupⅠ,the average daily feed intake,average daily gain,CSFV antibody blocking rate and content of IgG and IL-2 in serum of supplemented groupⅡwas significantly increased(P<0.05),and the diarrhea rate significantly decreased(P<0.05).The experiment indicates that adding antimicrobial peptides in diet can improve the growth performance,diarrhea rate and immunization effect of classical swine fever vaccine of weaned piglets,and the best effect is to add 0.10%.
