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。

Abstract:

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.

Key words: ‘Frizzle’ broiler, mulberry leaf powder, feed additives, growth performance, tissue and organ
