摘　　要：在文昌鸡日粮中添加发酵木薯渣粉,来替代日粮中的部分饲料原料,旨在减少文昌鸡日粮中玉米等原料的使用,达到节省粮食、降低饲养成本的目的。利用不同复合菌剂发酵得到的发酵木薯渣粉,以不同比例添加到文昌鸡日粮中,来替代等比例的饲料原料,然后与饲喂配合饲料组群的增重效果进行比较。试验结果表明:各试验组增重效果与对照组相比,差异均不显著(P>0.05),但综合考虑增重效果和经济效益初步得出:(1)日粮中用发酵木薯渣粉替代相同比例的不同饲料原料对文昌鸡雏鸡增重无显著影响,但可降低饲养成本;(2)经比较发现,用40%米曲霉、20%枯草芽孢杆菌和40%酿酒酵母组成的复合菌剂发酵得到的木薯渣粉,添加比例为15%,来替代9%的玉米粉、3%的花生粉和3%的麸皮是可行的,能够得到相对较好的增重效果。The study was that fermented cassava residue replace part of feed ingredients of Wenchang Chicken diets, aim to decrease the quantity of maize and reduce cost of raising. Different proportion fermented cassava residue that be fermented by different compound bacterium was utilezed, and weight gain be compared with the normal diets. The experimental results showed that： the effect of weight gain of all experimental groups was not different from control group significantly（P0.05）. However, considering the effect of weight gain and the economic benefits： （1）there was no significant impact on chicken weight gain by replacing the same proportion of feed ingredients with cassava residue, and it could reduce feed cost; （2）it found by comparison that the compound bacterium, when the proportion of Aspergillus oryzae, Bacillus subtilis and Saccharomycescerevisiae was 40：20：40 and the protortion of replacing was 15% , the effect of the chicken weight gain is better that other gorups.
