摘　　要：将４８００只１日龄樱桃谷雏鸭随机分成６组，每组８００只。Ⅰ组饲喂基础日粮，Ⅱ、Ⅲ、Ⅳ、Ⅴ组分别在基础日粮中添加２５０、５００、７５０和１０００ｍｇ／ｋｇ盐霉素预混剂，Ⅵ组添加２５ｍｇ／ｋｇ土霉素，试验期为６周，分前、中、后三期进行。结果表明：各处理组成活率均高于Ⅰ组（对照组）；２周龄后，添加盐霉素的各组试验鸭平均体重、日增重均显著高于Ⅰ组（Ｐ＜００５），其中Ⅲ组极显著高于Ⅰ组（Ｐ＜００１），Ⅵ组与Ⅰ组平均体重、日增重差异不显著（Ｐ＞００５）。２周龄后，Ⅲ、Ⅳ、Ⅱ组的料重比低于Ⅰ组，全期料重比以Ⅲ组最优，经济效益最佳。说明在肉鸭饲料中添加５００ｍｇ／ｋｇ盐霉素预混剂可获得较好的增重与料重比。ducks(1 day-old) were randomly divided to 6 equal groups.Groups Ⅰ～Ⅵ were supplied to 0,250,500,750 and 1000mg/kg selinomycin premix(contain 10% selinomycin) in basic diet,Group Ⅵ was provided 25mg/kg oxytetracycline.During the experiment period of 6 weeks.Survive rate,body weight,feed consumpation were recorded.The result indicated:the survive rates of all treatment groups were higher than groupⅠ.Supplement with selinomycin in diet could improve body weight of ducks significantly(P<0.05,v.s. groupⅠ),and group Ⅲ got the best effect (P<0.01,v,s. groupⅠ).There was no significant difference in body weight between group Ⅵ and groupⅠ. feed conversions of groupⅡ～Ⅳ were higher than group Ⅰ,and feed conversion of group Ⅲ was the highest in all groups. It seemed that ducks diet with 500mg/kg selinomycin premix could improve body weight and feed conversion.
