摘　　要：研究循环高温环境下精氨酸营养对肉鸭生长性能和免疫器官的影响。选择90只出壳健康商品樱桃谷肉鸭,随机分为3组,分别饲喂添加0%、0.5%和1.0%L-精氨酸的饲粮。结果显示:添加0.5%L-精氨酸可显著降低肉鸭生长全期(0～49日龄)的料重比(P<0.05),并可显著提高21日龄肉鸭肝脏指数和49日龄肝脏粗蛋白质的含量(P<0.05)。This experiment was conducted to investigate the influences of dietary arginine on growth performance and immune organs of ducks in summer. Ninety one-day-old healthy commercial cherry valley meat duck were randomly divided into 3 treat- ments, fed with the basal diet supplemented with 0%, 0.5%, 1.0% of L-arginine, respectively. The results indicated that： 0. 5%0L-arginine could significantly reduce feed to gain ratio of meat duck（0-49-day） in the full production period（P〈0. 05）, and the liver index at 21-day and the hepatic crude protein content at 49-day were increased by supplementing L-arginine（P〈0. 05）.
