摘　　要：选用28日龄罗斯308肉仔鸡162只,随机分为9个处理组,每组18只,设3个重复,每个重复6只,采用3×3三因子三水平有重复试验设计.在玉米-豆粕型日粮基础上添加不同水平的蛋氨酸硒(0,0.25,0.5 mg/kg)、甘氨酸锌(0,70,140mg/kg)和甘氨酸铜(0,30,60mg/kg).以饲喂基础日粮组为对照组,用以研究三者对肉仔鸡生长性能及屠体性状的影响,并初步探讨三者的互作效应.试验期3周,结果表明:日粮中添加不同水平蛋氨酸硒、甘氨酸锌、甘氨酸铜对肉仔鸡的料肉比、屠宰率、腹脂率、全净膛率均有互作效应.综合生长性能和屠体性状,日粮中添加0.25mg/kg蛋氨酸硒+70mg/kg甘氨酸锌+60mg/kg甘氨酸铜效果最佳.An experiment was conducted using a total of 162 four-week-old Rose 308 broilers to investigate the effects of adding Methionine-Se （0, 0.25, 0.5 mg/kg）, Glycine-Zn （0,70,140 mg/kg） and Glycine-Cu （0,30,60 mg/kg） to corn soybean diets on growth and slaughter performance in broilers and their interaction. Broilers were randomly divided into 9 treatments （18 for each treatment, 6 for each replicate）. A 3 ×3 experiment with replicates was designed. The basal diet was used as control group, and the experiment lasted for three weeks. The results showed： There were significant effects of interaction between Methionine-Se, Glycine-Zn and Glycine-Cu on feed gain ratio, slaughter rate, abdominal fat rate, the rate of the whole pure thorax. Analysis showed that, it was better for the test group to add 0.25 mg/kg Methionine-Se, 70mg/kg Glycine-Zn and 60 mg/kg Glycine-Cu at the same time.
