摘　　要：大曲丢糟为主要原料,利用纤维素酶为催化剂,绿色木霉和白地霉为生产菌进行丢糟发酵,采用L9(34)4因子3水平正交试验。得到的最佳工艺条件为:纤维素酶添加量0.02%,绿色木霉∶白地霉为1∶9,在28℃下培养5d。得到的饲料营养丰富,粗蛋白含量达22.5%。The distiller＇s grains of Daqu was used as raw materials to produce feedstuff by co-fermentation of green wooden mould and geotrichum candidum link with cellulase as catalyst. The optimum technical conditions were determined as follows through L9 （3^4）orthogonal test： 0.02 % addition level of cellulase, the ratio of green wooden mould and geotrichum candidum link was 1：9, and 5 d culture at 28℃. The produced feedstuffhas rich nutritions （the content of crude protein reaches at 22.5 %）.
