摘　　要：试验选用21日龄白番鸭480只，随机分为4组，每组5个重复．Ⅰ、Ⅱ、Ⅲ组分别饲喂含12％、14％、16％杂粕并添加溢多酶P-8306（0．2g／k）的日粮，对照组饲喂含7％杂粕（菜粕＋棉粕）无酶制剂的日粮，在相同的饲管条件下，观测各组番鸭体增重、饲料代谢率和屠体性能．结果表明：4～6周龄番鸭成活率和饲料利用率差异不显著（P〉0．05），体增重Ⅰ组比对照组低9％（P〈0．05），其他各组之间差异均不显著（P〉0．05）；6～8周龄体增重组间差异不显著（P〉0．05）、屠宰率、全、半净膛率、胸腿骨率、心脏、肝脏、小肠、腺胃和矾胃的重量组间差异均不显著且在含较高水平的杂粕日粮中添加溢多酶P-8306可达到与日粮杂粕含量较低相同的饲养效果；饲料效益以试验Ⅱ、Ⅲ组较高，其增重成本分别比对照组降低34.69％、4．93％．即每增重1kg可分别节约成本0．19元和0．02元.480 of 21 - day - old white muscovy, ducklings were randomly divided into 4 groups, of which each had 5 repeats, and eachrepeat contained 24 ducklings. The ducklings in control group were fed diet containing 7% mixed oil cake meals （rapeseed oil cake meal and cottonseed oil cake meal）but no added feed enzymes,while in test group Ⅰ, Ⅱ and Ⅲwere fed diet that contained 12%, 14% and 16% mixed oil cake meals and 0.2 g/kg of multienzyme preparation （Yiduozyme P- 8306）Feeding trial in all groups was conducted under the same nutritional level and management condition and lasted for 5 weeks. The productionperformances at different groups were evaluated. The results of whole feeding trial showed that at the age of 4-6 weeks in feed conversion rate （FCR）and survival rate between all groups were not significant（ P 〉 0.05）; the bodyweight gain in test group I was lower than that of the control group by 9% （P 〈 0.05）, but the differences between other groups were not significant （P 〉 0.05 ）;at the age of 8 weeks, the differences in bodyweight gain, slaughter rate, all- evisceration dressing percentage, semi - evisceration dressing percentage, breast fleshing, thigh muscle fleshing, the weights of heart, live grandular stomach and gizzard betweeneach group were not significant（ P 〉 0.05）. From the point of view of feeding efficiency, the addition of Yiduozyme P-8306 in dietcontaining ahigher amount of mixed oil cake meals could achieve as same the result as the diet containing a fewer amount of mixed oil cake meals; moreover, the cost for the bodyweight gain in test group Ⅰ and Ⅲwas lower than that of the control group by 4.69% and 4.93% ,respectively. The cost for each kilogram of bodyweight gain could be saved by 0.19 yuan and 0.20 yuan respectively.
