摘　　要：试验旨在探究饲粮中添加羟基蛋氨酸(MHA)螯合物对雪峰乌骨鸡种鸡生产性能、抗氧化性能、免疫与繁殖激素指标的影响。试验选用32周龄体重相近且健康的雪峰乌骨鸡324只,随机分为3组,每组6个重复,每个重复18只鸡。预试期2周,正式试验期8周。对照组饲喂基础饲粮,试验组分别在基础饲粮中添加30 mg/kg MHA-Zn(MZ组,以锌元素计)、25 mg/kg MHA-Mn(MM组,以锰元素计)、30 mg/kg MHA-Zn+25 mg/kg MHA-Mn(MZM组)。结果显示,与对照组相比,试验组乌骨鸡的产蛋率和健雏率均显著升高(P<0.05),MZM组乌骨鸡的孵化率显著高于对照组和MM组(P<0.05),MZ组和MZM组乌骨鸡的死胚率显著低于对照组、MM组(P<0.05)。MZM组乌骨鸡血清中黄体酮、促卵泡激素、雌二醇和甲状旁腺激素含量显著高于其他组(P<0.05)。MZM组乌骨鸡血清中总超氧化物歧化酶、过氧化氢酶活性显著高于对照组和MZ组(P<0.05)。MZM组乌骨鸡血清中锰超氧化物歧化酶、谷胱甘肽过氧化物酶活性显著高于对照组和MM组(P<0.05)。MM组和MZM组乌骨鸡血清中丙二醛含量显著低于对照组(P<0.05)。与对照组相比,MZM组乌骨鸡血清中免疫球蛋白A、免疫球蛋白M、白细胞介素-2的含量显著升高(P<0.05)。研究表明,在饲粮中添加MHA螯合物能够通过提高机体的抗氧化性能、免疫能力和繁殖激素水平,而改善雪峰乌骨鸡的生产性能。The experiment was conducted to investigate the effect of dietary hydroxy-methionine(MHA)chelate supplementation on the production performance,antioxidation performance,immune and reproductive hormone indexes of Xuefeng black bone breeding chickens.A total of 324 healthy 32-week-old Xuefeng black bone chickens with similar body weight were randomly divided into three groups,with six replicates per group and 18 chickens per replicate.The prefeeding period lasted for two weeks and the trial period lasted for eight weeks.The chickens in the control group were fed a basal diet.The experimental groups added 30 mg/kg MHA-Zn(MZ group,calculated by zinc),25 mg/kg MHA-Mn(MM group,calculated by manganese)and 30 mg/kg MHA-Zn+25 mg/kg MHA-Mn(MZM group)in the basal diet,respectively.The results showed that compared with the control group,the laying rate and healthy chick rate of the experimental groups were significantly increased(P<0.05).The hatching rate of the MZM group was significantly higher than that of the control group and MM group(P<0.05).The death rate of embryos in the MZ group and MZM group was significantly lower than that in the control group and MM group(P<0.05).The serum content of progesterone,folliclestimulating hormone,estradiol and parathyroid hormone in the MZM group was significantly higher than those in the other groups(P<0.05).The activity of total superoxide dismutase and catalase in the serum of MZM group was significantly higher than those of the control group and MZ group(P<0.05).The serum activity of manganese superoxide dismutase and glutathione peroxidase in the MZM group was significantly higher than those in the control group and MM group(P<0.05).The serum malondialdehyde content in the MM group and MZM group was significantly lower than that in the control group(P<0.05).Compared with the control group,the content of immunoglobulin A,immunoglobulin M and interleukin-2 in the serum of the MZM group was significantly increased(P<0.05).The study indicates that adding of MHA chelate in the diet c
