天蚕素抗菌肽对817肉杂鸡生长性能及免疫功能的影响
Effects of Antimicrobial Peptide on Growth Performance and Immune Function of 817 Broiler Hybrids
摘要
Abstract
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 5 groups with 6 replicates 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 150 mg/kg aureomycin,and that in groups Ⅰ,Ⅱ and Ⅲ were fed with basal diet supplemented 100,200 and 300 mg/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 42 days 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 200 mg/kg in this experiment.关键词
