摘　　要：[目的]为拓展饲料资源、降低饲料成本探索新途径。[方法]通过对木霉与酵母菌混合协同发酵生产蔗渣发酵饲料的研究,确立了由20%木霉T-1、10%扣囊拟内孢霉酵母E-1803组成的混合发酵体系;接种时先接种T-1,24 h后再接种E-1803液体种子,28℃恒温静置培养。固态发酵培养基组成为:蔗渣∶麸皮∶豆饼=5∶3∶2;(NH4)2SO41%,KH2PO40.2%,料水比1.0∶4.0。[结果]根据此工艺所得蔗渣发酵饲料分别含有5.78%可溶性还原糖、19.45%蛋白质及26.17%的粗纤维;其蛋白质含量比原发酵培养基提高了38.73%,粗纤维降解率40.46%。[结论]该产品具有较好的产品外观和风味,建议推广普及。[ Objective ] The aim was to explore a new way for expanding feed resources and reducing feed costs. [ Method ] Through study on producing sugarcane bagasses animal feed by fermentation of Trichoderma sp. and yeast, a mixed co-fermentation including 20% T-1 and 10% E-1803 was established. T-1 should be inoculated 24 h berfore E-1803 and cultured at 28℃constant temperature. The fermentation media were composed as following ： sugarcane bagasses/wheat bran/bean cake = 5/3/2, （ NH4 ） 2 SO4 1% , KH2 PO4 0.2% , 1.0：4.0 of dried material to water. According to this technology, the product was obtained after fermentation, containing 5.78% souble reducing saccharide, 19.45% protein and 26.17% crude fiber, which had been increased by 38.73% , and the crude firbe was reduced by 40.46%. [ Conclusion] The product shoud be generalized for its good appearance and flavor.
