摘　　要：选用28日龄广西玉林三黄鸡为试验对象,在肉鸡日粮中分别添加10%、20%、30%发酵木薯渣饲料进行养殖试验,然后对其生长性能、成活率、养殖成本及经济效益进行分析,并评价其应用效果。结果表明,与对照组(CK)相比,10%、20%、30%处理组肉鸡日均增重分别显著提高了7.02%、6.95%和6.18%;日采食量分别提高了5.95%、5.82%和21.49%;料肉比方面,10%、20%处理组均比CK降低了1%,而30%处理组比CK增加了14.5%;发病率方面,10%、20%处理组比CK分别降低了12%和6%,而30%处理组比CK增加了13%;经济效益分析发现,添加10%～20%微生物发酵木薯渣饲料饲喂肉鸡,可以降低养殖成本、提高成活率和经济效益,且以添加10%的量效果最佳。10%,20%,30% fermented cassava residue feed were added to Guangxi Yulin Sanhuang chicken with 28-day respectively,in order to analyze the effect of microbial fermentation cassava residue on broiler growth performance,survival rate,farming cost and economic benefits,and evaluate the application results.The results showed that compared to control group（CK）,daily average weight increased by 7.02%,6.95%,6.18% in the treatment groups,the difference was significant;daily feed intake increased by 5.95%,5.82% and 21.49%,the difference was significant;feed conversion of treatment group 2 and 3 decreased by 1%,that of treatment group 4 increased by 14.5% with significant difference;morbidity of treatment group 2 and 3 decreased by 12%,6%,respectively,that of treatment group 4 increased by 13% with significant difference.Profit analysis showed that through adding microbial fermentation of cassava residue feed to broiler with 10%～20%,it could reduce farming costs,improve survival rate and economic benefits,and the best of adding amount was 10%.
