摘　　要：选用1日龄樱桃谷肉鸭900只,分为3组,每组6个重复,每个重复50只,进行饲养试验。对照组饲喂玉米-豆粕-杂粕型基础饲粮,试验1、2组在基础饲粮基础上分别添加0.015%、0.025%复合酶制剂。结果表明,两试验组肉鸭只均日增重、干物质、能量和粗蛋白质代谢率均显著高于对照组;饲料增重比显著低于对照组,试验1组生长性能和养分代谢率均最高。结论,复合酶制剂可提高肉鸭生产性能、促进营养物质吸收利用,但添加水平应适量。The experiment was conducted to evaluate the effects of multi-enzyme preparations on growth performance and metabolic rates, of nutrients of meat ducks. Nine hundred meat ducks with 1-day-old were randomly divided into 3 treatments. Each treatment had 6 replicates with 50 ducks per replicate. The control group was fed basal diets （control）. Groups 1 and 2 were fed basal diets supplemented with multi-enzyme preparations at the level of 0.015% and 0.025%, respectively. The results showed that average daily gain, metabolic rates of dry matter, energy and protein were significantly increased in groups 1 and 2. Whereas, F/G were lower than that in the control group. The growth performance and metabolic rates of nutrients in group 1 were the highest. Conclution： Muhi-enzyme preparations could improve the growth performance of meat duck and promote the utilization of nutrients, but the level should be suitable.
