摘　　要：本试验选用22日龄爱拔益加商品代肉仔鸡336只(公母各半),随机分为7个处理,每个处理8个重复(公母各4个重复),每个重复6只鸡。分别饲喂玉米、豆粕、棉粕、菜粕、玉米-豆粕、玉米-棉粕、玉米-菜粕7种试验日粮,测定28日龄肉仔鸡的表观代谢能(AME)和氮校正表观代谢能(AMEn)。玉米、豆粕、棉粕、菜粕的AME分别为14.82、12.10、11.17、9.79MJ/kg,AMEn分别为14.80、11.81、10.81、9.60MJ/kg。三种混合日粮AME和AMEn的预测值与测定值差异不显著(P>0.05),表明玉米和豆粕、棉粕、菜粕的AME和AMEn存在可加性。Three hundred and thirty-six 22-day-old AA broilers were randomly assigned into 7 treatments,with 8 replicates each treatment （4 replicates for male and female broilers respectively）.Seven diets were prepared by corn,soybean meal,cottonseed meal,rapeseed meal,corn mixed soybean meal,corn mixed cottonseed meal and corn mixed rapeseed meal.Apparent metabolizable energy （AME） of corn,soybean meal,cottonseed meal and rapeseed meal were 14.82,12.10,11.17,9.79 MJ/kg,and AMEn were 14.80,11.81,10.81,9.60 MJ/kg respectively.There were no significant differences between predicted and measured values for AME and AMEn in three mixed diets（P 〉 0.05）.Results of the experiment demonstrated that AME and AMEn of broilers between corn and soybean meal,cottonseed meal,rapeseed meal were additive.
