摘　　要：本文研究了3～5周龄肉鸭日粮中玉米蛋白饲料适宜添加比例。480只21日龄健康樱桃谷肉鸭,按体重相近的原则随机分为4组,每组设6个重复,各重复20只。对照组饲喂基础日粮,试验组分别在基础日粮中添加5%、8%、11%玉米蛋白粉代替部分豆粕。试验期间记录各组体增重及耗料量等,试验结束后,测定各组肉鸭的生产性能、屠宰性能及血清中尿素氮、总蛋白、甘油三酯含量。结果表明,3种添加比例对肉鸭体增重、料重比和屠宰性能无显著影响(P>0.05)。5%、8%添加量对肉鸭血清尿素氮、总蛋白、甘油三酯含量无显著影响(P>0.05),日粮中添加11%玉米蛋白饲料,尿素氮显著增加(P<0.05)。本试验条件下,日粮中添加8%玉米蛋白饲料,肉鸭生产性能最理想,单位增重饲料成本比基础日粮组低3.82%,胴体品质也有一定改善,且对血清中尿素氮、总蛋白、甘油三酯含量无显著影响。The trial was conducted to study the appropriate content of corn gluten meal in 3 - 5 weeks duck diet.480 cherry valley ducks were randomly divided into four groups by weight at 21 d of age.Every group included 6 replications which contained 20 ducks each.The control group was fed with the basal diet,while in treatment groups added 5 % ,8 % and 11% corn gluten meal.Body gain and consumption of feed during the test ,the production performance ,slaughter performance and the contents of urea nitrogen,total protein and triglyceride level in serum were determined.The results showed that there was no significant effect on body gain,feed transformation efficiency and slaughter performance （P 〉 0.05 ）.The difference of urea nitrogen, total protein and triglyceride levers was not significant with the addition of 5 % and 8 %（P 〉 0.05 ）, but adding 11% made serum urea nitrogen increase significantly （P 〈 0.05 ）.Under the experimental con- ditions, the production performance was more desirable ,the cost was lower about 3.82 % ,and the quality of carcass got a certain improvement with the addition of 8 % ,but there was no significant effects on serum biochemical parameters.
