摘　　要：本试验旨在探讨笼养蛋鸭产蛋高峰期饲粮中添加不同水平抗菌肽对其生产性能、蛋品质、血清生化指标、抗氧化能力及免疫功能的影响。选取640羽产蛋率相近的220日龄绍兴鸭,随机分为4组,每组8个重复,每个重复20羽。对照组饲喂基础饲粮,试验组分别在基础饲粮中添加100、200和400 mg/kg抗菌肽。预试期7 d,正试期56 d。结果显示:1)与对照组相比,饲粮中添加200 mg/kg抗菌肽可显著提高产蛋率(P<0.05),并可显著降低料蛋比(P<0.05)。2)与对照组相比,饲粮中添加100、200和400 mg/kg抗菌肽对各蛋品质指标均无显著影响(P>0.05)。3)与对照组相比,饲粮中添加200 mg/kg抗菌肽可显著提高血清总蛋白、白蛋白、球蛋白含量(P<0.05),并可显著降低血清尿酸含量、谷丙转氨酶活性(P<0.05)。4)与对照组相比,饲粮中添加200和400 mg/kg抗菌肽可显著提高血清总抗氧化能力(P<0.05);饲粮中添加200 mg/kg抗菌肽可显著提高血清过氧化氢酶活性(P<0.05);饲粮中添加100、200和400 mg/kg抗菌肽均可显著提高血清超氧化物歧化酶和谷胱甘肽过氧化物酶活性(P<0.05),并可显著降低血清丙二醛含量(P<0.05)。5)与对照组相比,饲粮中添加200 mg/kg抗菌肽添可显著提高血清免疫球蛋白G和免疫球蛋白M含量(P<0.05)。综上所述,抗菌肽可提高产蛋高峰期笼养蛋鸭的产蛋率,降低料蛋比,增强机体抗氧化能力和免疫功能。在本试验条件下,产蛋高峰期笼养蛋鸭饲粮中添加200 mg/kg抗菌肽较为适宜。This study was conducted to investigate the effects of diet supplemented with different levels of antimicrobial peptide on performance,egg quality,serum biochemical indices,antioxidant capacity and immune function of caged-rearing laying ducks during peak laying period.A total of 640 Shaoxing ducks aged 220 days with comparable levels of productivity were randomly divided into 4 groups with 8 replicates in each group and 20 ducks in each replicate.Ducks in the control group were fed a basal diet,in contrast,those in the experimental groups were given diets supplemented with 100,200 and 400 mg/kg antimicrobial peptide,respectively.The pre-trial period lasted for 7 days and the formal trial period lasted for 56 days.The results showed as follows:1)compared with the control group,the supplementation of 200 mg/kg antimicrobial peptide significantly increased the laying rate(P<0.05),and significantly decreased the ratio of feed to egg(P<0.05).2)Compared with the control group,adding 100,200 and 400 mg/kg of antimicrobial peptide in diets had no significant effects on egg quality indices(P>0.05).3)Compared with the control group,the supplementation of 200 mg/kg antimicrobial peptide significantly increased the contents of serum total protein(TP),albumin(ALB)and globulin(GLB)(P<0.05),and significantly decreased the serum uric acid(UA)content and alanine aminotransferase(ALT)activity(P<0.05).4)Compared with the control group,the supplementation of 200 and 400 mg/kg antimicrobial peptide significantly increased the serum total antioxidant capacity(T-AOC)(P<0.05);the supplementation of 200 mg/kg antimicrobial peptide significantly enhanced the serum catalase(CAT)activity(P<0.05);the supplementation of 100,200 and 400 mg/kg antimicrobial peptide significantly increased the activities of serum glutathione peroxidase(GSH-Px)and superoxide dismutase(SOD)(P<0.05),while significantly decreased the content of serum malondialdehyde(MDA)(P<0.05).5)Compared with the control group,supplementation of 200 mg/kg antimicrobial peptide si
