摘　　要：【目的】考察戊糖乳杆菌发酵香蕉副产物的影响因素,考察青贮发酵香蕉副产物对山羊养殖的影响。【方法】以香蕉副产物为主要原料,试验不同吸水剂、营养添加物以及不同发酵菌株组合,对青贮发酵后的pH值和营养指标进行分析;山羊养殖试验中分组饲喂象草、青贮玉米秸秆、青贮香蕉剩余物,比较山羊养殖增重效果。【结果】戊糖乳杆菌发酵香蕉副产物时,干菌糠为最佳吸水剂,麦麸为最佳营养添加物,戊糖乳杆菌与酵母菌的最佳比例为1∶1;养殖山羊时发酵香蕉副产物可占粗饲料的70%,养殖增重率高于象草组和青贮玉米秆组。【结论】戊糖乳杆菌是香蕉副产物的适宜发酵菌株,青贮发酵香蕉副产物是山羊养殖的优良粗饲料。【Objective】In order to study on the effect of Lactobacillus pentosus to the silage of banana residues,and the effect of silage fermentation banana by-products on goat culture was investigated.【Method】Several water absorbents,additional nutrients and strains were applied to the fermentation of banana residues.The pH value and other nutritional index were analyzed after fermentation.Three groups,i.e.elephant grass,silage of corn stalk and silage of banana residues,were applied to goat breeding.【Result】The best water absorbent and additional nutrient was dry mushroom bran and wheat bran respectively.And 1∶1 was the best ratio between Lactobacillus pentosus and yeast in silage of banana residues.【Conclusion】Lactobacillus pentosus was suitable for the fermentation of banana residues.The silage of banana residues was an excellent roughage for goat breeding.
