羟基蛋氨酸螯合物对雪峰乌骨鸡种鸡生产性能、抗氧化、免疫与繁殖激素指标的影响
Effect of hydroxy-methionine chelate on production performance,antioxidant,immune and reproductive hormone indexes of Xuefeng black bone breeding chickens
摘要
Abstract
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 pre-feeding 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,follicle-stimulating 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 can improve the production performance of Xuefeng black bone chickens by increasing antioxidation performance,immune and reproductive hormone levels.关键词
