摘要：

试验旨在研究天蚕素抗菌肽对817肉杂鸡生长性能和免疫功能的影响。选取1日龄817肉杂鸡900羽,随机分为5个处理组(对照组、抗生素组及Ⅰ、Ⅱ、Ⅲ组),每组6个重复,每个重复30羽。对照组饲喂基础日粮,抗生素组在基础日粮中添加150mg/kg金霉素,Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加100、200和300mg/kg天蚕素抗菌肽,试验期42d。结果显示,Ⅱ、Ⅲ组能显著提高1~21日龄817肉杂鸡的平均日增重(P<0.05),显著降低料重比(P<0.05);显著提高21、42日龄817肉杂鸡的胸腺、法氏囊和脾脏指数(P<0.05);显著提高42日龄肉杂鸡的ND抗体水平和T淋巴细胞转化率(P<0.05),表明在日粮中添加天蚕素抗菌肽能提高817肉杂鸡的生长性能和免疫功能,在本试验条件下,适宜的添加量为200mg/kg。

摘要：

This experiment was conducted to investigate the effects of antimicrobial peptide on growth performance and immune function of 817 broiler hybrids.Nine hundred one-day-old 817 broiler hybrids were chosen and randomly divided into 5groups with 6replicates per group and 30 broilers per replicate.The broilers in control group were fed with basal diet,broilers in the antibiotic group were fed with basal diet supplemented 150mg/kg aureomycin,and that in groupsⅠ,ⅡandⅢ were fed with basal diet supplemented 100,200 and 300mg/kg antimicrobial peptide,respectively.The experiment period was 42 days.The results showed that average daily gain of 817 broiler hybrids in groups Ⅱ and Ⅲ was significantly increased(P<0.05),meanwhile the F/G was significantly decreased at 1-21 days old(P<0.05).The immune organ indexes of thymus,bursa of Fabricius and spleen were significantly increased at 21 and 42days old(P<0.05),and the antibody level against ND and T lymphocyte transformation rate of 42 days old 817 broiler hybrids were improved(P<0.05).It indicated that antimicrobial peptide could increased growth performance and immune function of 817 broiler hybrids as same with aureomycin,and appropriate dosage of antimicrobial peptide was 200mg/kg in this experiment.
