摘  要：
文章研究了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。选用300只0日龄广西快大型黄羽肉鸡(雌性),随机分为5组,每组6个重复,每个重复10只鸡,进行为期63d的饲养试验。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,添加水平为Fe100mg/kg、Cu20mg/kg、Mn120mg/kg、Zn120mg/kg;试验组分别用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%。试验表明:与对照组相比,用不同比例蛋氨酸螯合物(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效果良好。

摘  要：
The experiment was conducted to investigate the effects of substituting amino acid-chelated trace element for inorganic trace element in diet of broiler on growth performance,nutrient metabolizability and content of the trace elements in feces.300 zero-day-old Guangxi yellow broilers(female) were randomly divided into 5 groups with 6 replicates and 10 birds per replicate.The feeding trial lasted for 63 days.The dietary of control group Fe,Cu,Mn and Zn were provided by FeSO4 H2O,CuSO4 5H2O,MnSO4 H2O and ZnO,the levels were Fe100mg/kg,Cu 20mg/kg,Mn 120mg/kg,Zn 120mg/kg respectively.The experiment group the dietary inorganic element levels of 25%,50%,75% and 100% were substituted by the methionine-chelated Fe,Cu,Mn,Zn of 12.5%,25.0%,37.5% and 50.0% respectively.The results showed that substituting methionine-chelated Fe,Cu,Mn,Zn for dietary inorganic salts with different proportion could,to a certain extent,increase the growth performance,improve dietary nutrient utilization,increase feeding benefit and reduce the trace elements excretion in feces.Especially,the effect of substituting 37.5% methionine-chelated Fe,Cu,Mn and Zn for 75% of the dietary corresponding inorganic trace elements was better than others.
