摘要
选用1200只7日龄商品代AA肉用仔鸡,随机分成6个处理,每个处理4个重复,每个重复50只鸡,用3D复合氨基酸螯合锌、锰分别替代基础日粮中相应无机元素水平的0%,20%,40%,60%,80%,100%,研究其对肉用仔鸡生产性能、腿病发生率和死亡率的影响以及适宜替代比例。试验结果表明:饲粮添加复合氨基酸螯合锌、锰对肉仔鸡生产性能、腿病发生率和死亡率有一定的改善作用,与相应无机元素相比,饲养全期和相对增长率提高,其中试验组4(60%)和试验组5(80%)的体重增长率明显提高(P<0.05),其饲料转化率分别较对照组增加11.8%和11.0%。从本试验各项指标综合考虑,肉仔鸡饲料中3D复合氨基酸螯合锌、锰替代相应无机微量元素的适宜比例为60%。
1200 7-day-old, healthy AA broilers were divided into six treatments randomly with 4 repeats in each treatment and 50 broiler chickens per repeat. The inorganic element level in the basic diet,0%, 20%,40%,60%,80%,100% was replaced by 3D-Zn,3D-Mn to study its effect on the growth performance, disease occurrence rate in leg and death rate of broiler chickens, and ascertain the optimum combination level . The results showed： trace element amino acid chelates were efficacious for improving growth performance, disease occur rate in leg and death rate of broiler chickens. Compared with corresponsive inorganic microelement sulfate, the abstract body weight and relative body weight increased during the whole feeding time , specially the body weight of treatment 4 （60%） and 5 （80%） increased significantly（p 〈0.05） ,and the feed conversion of which increased by 11.8% ,and 11.0%. Taking into account of each index in this experiment, the optimum combination level of complex amino acid chelate （3D Zn and 3D Mn） was 60%.
