摘　　要：试验选用35日龄快大型黄羽肉鸡96只,随机分为4组,每组6个重复,每个重复4只鸡,分别饲喂以玉米淀粉、大麦、鱼粉和花生粕为基础原料配制的4种日粮。采用指示剂法测定玉米淀粉、大麦、鱼粉和花生粕的总能消化率、表观代谢能(AME)和氮校正表观代谢能(AMEn)。结果表明:黄羽肉鸡玉米淀粉、大麦、鱼粉和花生粕的总能消化率分别为68.77%、65.67%、89.57%、75.85%,AME分别为8.82、9.45、13.27、11.22 MJ/kg,AMEn分别为8.71、9.34、13.00、10.99 MJ/kg。The experiment was selected 96 35-day old yellow-feathered broiler chickens and randomly assigned into4 treatments,with each group represented by 6 replicates of 4 broilers per replicate.Four diets were prepared based on corn starch,barley,fish meal and peanut meal.Total digestibility,AME and AMEn of corn starch,barley,fish meal and peanut meal were evaluated by indiator method.The results showed that the digestibility of gross energy of corn starch,barley,fish meal and peanut meal were 68.77%,65.67%,89.57%,75.85%,AME were 8.82,9.45,13.27,11.22 MJ/kg,and AMEn were 8.71,9.34,13.00,10.99 MJ/kg respectively.
