2、：体增重以空白对照组(组I)最低，较空白对照组，9％组(组V)显著提高(P(0．05)，其余各组极显著提高(P<0．01)；料重比6％组(组1V)最低，与空白对照组差异极显著(0．O1，其他各组间差异均不显著(0．05)；成活率空白对照组最低，抗生素组(组Ⅱ)、9％组与空白对照组差异极显著(p

3、合饲料中用6％发酵豆粕替代普通豆粕最为适宜，可提高肉鸡生长性能，极显著降低料重比，但与抗生素组相比差异不显著。关键词：发酵豆粕；肉鸡；生长性能；屠宰性能中图分类号：$831．5文献标志码：A论文编号：2012—0832EfectsofFermentedSoybeanMealonGrowthandSlaughterPerformanceofBroilersQiRuixue，WangQuanxi，rangYufen，LiuHao，WangChangkang，ChenQingda，LinYuhuan(CollegeofAnimalScience，FujianAgricultu
