摘　　要：试验选用180只体重为59.46±0.09g的1日龄樱桃谷肉仔鸭,随机分为4组,即对照Ⅰ组、对照Ⅱ组、试验Ⅰ组和试验Ⅱ组,分别饲喂玉米-豆粕型日粮、稻谷-玉米-豆粕型日粮以及在稻谷-玉米-豆粕型日粮中分别添加复合酶制剂500和1000g·t-1,每组设3个重复,每个重复15只。试验期35d。试验结果表明,试验Ⅰ组和试验Ⅱ组肉鸭较对照Ⅰ组平均日增重显著提高(P<0.05),料重比显著降低(P>0.05);试验Ⅰ组和试验Ⅱ组肉鸭较对照Ⅰ组CP、AME和NDF的表观消化率均显著提高(P<0.05)。One hundred and eighty （1 d old） cherry valley ducks （59.46±0.09 g） were chosen to be randomly divided into 4 groups, and lout different diets including corn-soybean （control group Ⅰ ）, paddy-corn-soybean （control group Ⅱ）, adding compound enzyme complex （500 g.t^-1）. in paddy-corn-soybean based diet （trial group Ⅱ ） and adding compound enzyme eomplex （1 000 g.t^-1） in paddy-corn-soybean based diet （trial group Ⅱ） were fed, with 3 replicates in eaeh group and 15 ducks in each group in 35 d. The results showed that the average daily gain of trial group I and trial group Ⅱ were significantly increased comparing with control group [ （P〈0.05）, and the ratio of Iced gain was significantly decreased（P〈0.05）. The apparent digestibility of erude fat, apparent metab- olizable energy（AME） and neutral detergent fiher of trial group Ⅰ and trial group Ⅱ were significantly increased comparing with control group Ⅰ （P〈0.05）.
