摘　　要：本试验旨在研究复合非淀粉多糖酶制剂中补充α-半乳糖苷酶对黑羽番鸭生产性能的影响。选用1日龄黑羽番鸭1600羽,随机分为4个处理,每处理4个重复,每个重复100羽。试验分为1～21、22～42d和43～65d三个阶段,持续65d。Ⅰ组饲喂基础日粮作为对照;Ⅱ组和Ⅲ组分别在基础日粮中添加FE806L和AG201L酶;Ⅳ组在基础日粮上降低代谢能209kJ/kg,再添加AG201L酶。试验分3个阶段进行。结果表明,日粮添加FE806L和AG201L均提高了番鸭1～21、22～42d、43～65d和1～65d平均日增重,并不同程度降低了番鸭的料肉比,其中Ⅲ组各阶段料肉比最低,分别比Ⅰ组和Ⅱ组低8.81%、5.03%、3.40%、4.08%和4.61%、2.07%、1.38%、2.08%,但各组差异不明显(P>0.05);降低能量并添加AG201L酶的Ⅳ组,肉鸭的增重较对照Ⅰ组和试验Ⅱ、Ⅲ组略有降低,但各组间差异不明显(P>0.05)。整个试验期内番鸭存活率以试验Ⅲ组最高,达98.53%,其次为Ⅱ组,最低为Ⅰ组,但组间无明显差异(P>0.05)。This experiment was conducted to study the effects of non-starch-polysaccrides complex enzymes supplemented with α-galactosidase on the growth performance of black Muscovy duck.One thousand six hundred 1-day-old ducks were randomly assigned to four groups with four replicates of one hundred ducks.The experiment was divided into three periods（1 ～ 21 d,22 ～ 42 d and 43 ～ 65 d）and lasted for 65 days.Group Ⅰ was fed basal diets as a control;Group Ⅱ and Ⅲ were fed basal diets supplemented with FE806L and AG201L complex enzyme respectively;While Group Ⅳ was fed basal diets supplemented with AG201L and decreased metabolize energy 209 kJ/kg.The results showed when ducks were fed basal diet supplemented with FE806L and AG201L,the average daily weight gain（ADG）of 1 ～ 21 d,22 ～ 42 d and 1 ～ 65 d were increased,feed to gain ratio（F/G）were decreased,among them the lowest was found in group Ⅲ, which were 8.81 %,5.03 %,4.04 %,4.08 % and 4.61 %,2.07 %,2.69 %,2.08 % lower than group Ⅰ and Ⅱ,but there were no significant differences among groups （P 〉 0.05 ） ;The average daily weight gain （ADG）of Group Ⅳ was lower than group Ⅰ , Ⅱ and Ⅲ ,but there were no differences among groups（P 〉 0.05）.The survival rate of the whole period in group m was the highest,which was 98.53 %,group Ⅱ was second and the lowest was found in group Ⅰ ,but there were no differences among groups（P 〉 0.05）.
