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。对照组饲喂玉米一豆粕一杂粕型基础日粮,试验1、2组在基础日粮基础上分别添加0.015%、0.025%复合酶制剂。结果表明,两试验组只均日增重、重料比均显著高于对照组,干物质、能量和粗蛋白质代谢率也显著增高;试验1组生长性能和养分代谢率均最高。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 prepara- tions on growth performance and metabolic rate of nutrients of meat duck. 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). Group 1 and 2 were fed basal diets supplementing with multi - enzyme preparations at the level of 0. 015% and 0. 025% respectively. The result showed that, body gain and feed transformation efficiency in group l and 2 were significantly higher than control group, metabolic rate of dr), matter, energy and protein also increased significantly; tile growth performance and metabolic rate of nutrient in group 1 were the highest. Multi - enzyme preparations could improve the growth performance of meat duck, promote utilizing the nutritive material, but the addition should be suitable.
