摘　　要：研究氨基酸微量元素螯合物替代饲粮中无机微量元素对肉鸡生产性能、饲粮养分代谢率和粪中微量元素含量的影响。1组为对照组饲喂基础饲粮,其Fe、Cu、Mn、Zn分别由硫酸亚铁、硫酸铜、硫酸锰和氧化锌提供,添加水平分别为Fe 100 mg/kg、Cu 20 mg/kg、Mn 120 mg/kg和Zn 120 mg/kg;2、3、4和5组分别用12.5%、25.0%、37.5%和50.0%的蛋氨酸螯合铁、铜、锰、锌替代基础饲粮各相应无机微量元素的25%、50%、75%和100%。63 d的试验结果表明:与对照组比较,用不同水平蛋氨酸螯合物(铁、铜、锌、锰)替代相应无机盐可一定程度提高肉鸡的生产性能,改善饲粮养分利用率,提高养殖效益,降低粪中微量元素的排泄量,尤以37.5%的蛋氨酸微量元素螯合物替代饲粮中75%的相应无机微量元素的效果良好。The effects of amino acid chelated trace element instead of inorganic trace element in the broiler diet on growth performance, metabolic rate of dietary nutrients and content of trace elements in feces were studied. Group I was fed with basal diet as the con- trol group. Fe, Cu, Mn, Zn in the diet were offered respectively by ferrous sulfate, copper sulfate, manganese sulfate and zinc oxide. The adding levels were respectively Fe 100 mg/kg, Cu 20 mg/kg, Mn 120 mg/kg and Zn 120 mg/kg. Group Ⅱ, Ⅲ,Ⅳ and Ⅴ used 12.5 %, 25.0%, 37.5 % and 50.0% of methionine chelated trace elements of iron, copper, manganese, zinc respectively instead of the corresponding inorganic trace elements of 25%, 50 %, 75 %and 100% in the basal diet. The 63-day test showed that： compared with the control group, using different levels of methionine chelated trace elements （iron, copper,zinc and manganeseto） instead of the cor- responding salts in the diet can improve, to a certain extent, the broilers＂ growth performance, nutrient utilization and farming efficiency and reduce fecal excretion of trace elements. The optimum formula was using 37.5 % methionine chelated trace element instead of 75 % of the corresponding inorganic trace elements in the diet.
