摘　　要：旨在探讨在日粮中添加桑叶粉对‘麒麟’肉鸡早期生长性能和组织器官的影响。选择健康状况良好的1日龄‘麒麟’母肉鸡144只,随机分为A、B、C和D 4组,每组6个重复,每个重复6只鸡,分别饲喂在基础日粮中添加0.0%、1.0%、3.0%和5.0%的桑叶粉的饲粮,进行为期28天的饲养试验。结果表明:在日粮中添加桑叶粉能一定程度地降低‘麒麟’肉鸡的平均日增重和提高料重比,当添加量达3.0%以上时显著提高料重(P<0.05),添加量达5.0%时显著降低平均日增重(P<0.05);对平均日采食量和内脏绝对重量和相对指数无显著影响(P>0.05);可一定程度提高肠道长度及相对指数,但差异不显著(P>0.05)。在从提高生长性能方面考虑,在1~28日龄的‘麒麟’肉鸡日粮中不必添加过多的桑叶粉。This study is to determine the effect of mulberry leaf powder on growth performance and organ development of‘Frizzle’broiler.A total of 144 one-day-old female‘Frizzle’broilers were allocated to 4 groups with 6 replications(6‘Frizzle’broilers/pen).4 groups were set up:A group(basal diet),B group(A+1.0%mulberry leaf powder),C group(A+3.0%mulberry leaf powder),D group(A+5.0%mulberry leaf powder).The experiment lasted for 28 days.The results showed that:dietary mulberry leaf powder supplementation decreased average daily gain(ADG)and increased the feed conversion ratio of‘Frizzle’broiler.Dietary 3.0%mulberry leaf powder supplementation increased feed conversion ratio significantly(P<0.05).Dietary 5.0%mulberry leaf powder supplementation decreased ADG significantly(P<0.05).No difference(P>0.05)was observed in the average daily feed intake,absolute organ weight,and relative organ index.Dietary mulberry leaf powder supplementation could improve the intestinal length and relative index to some extent,but not significantly(P>0.05).In view of the‘Frizzle’broilers’growth performance,it is not necessary to supplement much dietary mulberry leaf powder in the daily ration of‘Frizzle’broilers from1-28 days of age.
