| 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150 mg/kg金霉素，Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加100、200和300 mg/kg天蚕素抗菌肽，试验期42 d。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200 mg/kg。 |

| 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. |
