摘　　要：试验旨在探究饲粮中添加金银花黄芩提取物对产蛋后期蛋鸡生产性能、蛋品质、抗氧化和免疫功能、脂质代谢及蛋黄胆固醇含量的影响。选取产蛋率相近的70周龄新杨黑羽蛋鸡240只,分为2组,对照组饲喂基础饲粮,试验组在基础饲粮中添加金银花黄芩提取物(500 mg/kg),每组6个重复,每重复20只鸡,试验期70 d。结果表明:与对照组相比,①试验组全期产蛋率极显著提高(P<0.01),料蛋比极显著降低(P<0.01);②试验组蛋白高度、哈夫单位和蛋黄颜色显著提高(P<0.05);③试验组血清谷胱甘肽过氧化物酶、超氧化物歧化酶和过氧化氢酶水平显著提高(P<0.05),总抗氧化能力极显著提高(P<0.01),血清丙二醛含量显著降低(P<0.05);④试验组血清免疫球蛋白A(IgA)和免疫球蛋白G(IgG)含量极显著提高(P<0.01),免疫球蛋白M(IgM)显著提高(P<0.05);⑤试验组血清三酰甘油含量显著降低(P<0.05),总胆固醇含量极显著降低(P<0.01),血清高密度脂蛋白胆固醇含量极显著提高(P<0.01);⑥试验组蛋黄胆固醇含量极显著降低(P<0.01)。综上所述,饲粮中添加500 mg/kg金银花黄芩提取物可提高蛋鸡抗氧化和免疫功能,进而促进生产性能和蛋品质的提高,并同时改善蛋鸡脂质代谢,降低蛋黄胆固醇含量。This study was conducted to evaluated the effects of extracts from Flos lonicerae combined with Baikal skullcap on production performance,egg quality,antioxidant and immune functions,lipid me⁃tabolism and yolk cholesterol content of laying hens during the late laying period.Two hundred and forty healthy Xinyang black-feathered laying hens aged at 70 weeks with similar body weight and laying rate were randomly divided into control group and experimental group with six replicates in each group and 20 hens in each replicate.Laying hens in the con⁃trol group were fed a basal diet,and those in the experimental group were fed the basal diet sup⁃plemented with 500 mg/kg Flos lonicerae and Bai⁃kal skullcap extracts.The trial period lasted for 70 days.The results showed that:compared with the control group,①The full period of laying rate in the experimental group was significantly in⁃creased(P<0.01),and the feed to egg ratio in the experimental group was significantly decreased(P<0.01);②The albumen height,haugh unit and yolk color in the experimental group were significantly in⁃creased(P<0.05);③The levels of glutathione peroxidase,superoxide dismutase and catalase in serum of experimental group were significantly increased(P<0.05),the serum total antioxidant capacity level in the experimental group was significantly increased(P<0.01),and the serum malondialdehyde content in the experimental group was significantly decreased(P<0.05);④The contents of IgA and IgG in serum of experimental group were significantly increased(P<0.01),and the content of IgM in serum of experimen⁃tal group was significantly increased(P<0.05);⑤The content of triglyceride in serum of experimental group was significantly decreased(P<0.05),the content of total cholesterol in serum of experimental group was significantly decreased(P<0.01),and the serum high-density lipoprotein cholesterol content in the experimental group was significantly increased(P<0.05);⑥The yolk cholesterol content in the exper⁃imental group was signifi
