摘　　要：本试验旨在研究黄芪等8味中药组成的复方中药制剂对肉鸡免疫、抗氧化、生长和屠宰性能、饲粮养分利用率的影响。420只1日龄白羽肉鸡随机分为7组,每组6个重复,每重复10只鸡,1-5组饮水中分别添加0.04%、0.05%、0.07%、0.10%、0.20%复方中药制剂,6组为空白对照组,7组为抗生素对照组。结果表明:(1)血清新城疫抗体效价,第5组显著高于空白对照组(P<0.05);血清免疫球蛋白A(Immunoglobulin A,IgA)含量,各试验组显著高于第6组(P<0.05或0.01);血清免疫球蛋白M(Immunoglobulin M,IgM)含量,第2-5组极显著高于第6-7组(P<0.01);血清免疫球蛋白G(Immunoglobulin G,IgG)含量,第2-5组显著高于第6组(P<0.05或0.01);血清干扰素(Interferon-γ,IFN-γ)含量,第3-5组显著高于第6-7组(P<0.05或0.01)。(2)血清超氧化物歧化酶(Superoxide Dismutase,SOD)活性,第5组显著高于空白对照组(P<0.05);血清谷胱甘肽过氧化物歧化酶(Glutathione peroxidase,GSH-Px)活性,第3-5组显著高于第6组(P<0.05或0.01),第5组显著高于第7组(P<0.05);血清丙二醛(Malondialdehyde,MDA)含量,第3-5组极显著低于第6组(P<0.01)。(3)1-14日龄与26-42日龄,第5组平均日增重显著高于第7组(P<0.05);1-14日龄,第3-5组平均日采食量显著高于第7组(P<0.05或0.01);15-25日龄,第5组平均日采食量显著高于第7组(P<0.05);(4)全净膛率第5组显著高于第2-4组、6-7组(P<0.05或0.01);半净膛率第2-4组极显著高于第6组(P<0.01);第5组腿肌率显著高于第6、7组(P<0.05)。(5)饲粮粗蛋白质表观利用率第4-5组显著高于第7组(P<0.05),钙表观利用率第4组显著高于第7组(P<0.05)。说明复方中药对肉鸡免疫、抗氧化、生长和屠宰性能、饲粮养分利用率均有改善作用,作用效果优于抗生素组,适宜使用剂量0.20%。The aim of present study is to research the effect of 8 compound traditional Chinese(TM)medicine preparations on immunity,anti-oxidation,growth and slaughter performance,and dietary nutrient utilization of broilers.Four hundred twenty white feathered broilers in 1 day old were divided into 7 groups,randomly.The results showed that 0.20%TM significantly increased serum newcastle disease antibody titer.All TM concentration group from 0.04%-0.20%increased IgA content than control group.TM concentration of 0.05%-0.20%enhanced the level of IgG and IgM in serum compared with control group.While 0.07%-0.20%TM increased IFN-γinterferon content.0.20%TM treatment also enhanced serum super-oxide dismutase activity.TM concentration at 0.07%-0.20%displayed positive effect on glutathione peroxidase activity but negative effect on malondialdehyde level than control group.High concentration of TM treatment also increased daily weight gain,average daily feed intake,complete evisceration rate,half evisceration rate,leg muscle rate and calcium apparent utilization rate.In conclusion,TM treatment can improve immunity,anti-oxidation,growth and slaughter performance of broiler chickens.
