摘　　要：将玉米秸秆粉中加入10%小麦麸和适量的营养盐,调整其水分至70%,经由白地霉、近平滑假丝酵母、康宁木霉和绿色木霉组成的复合真菌,在30℃有氧条件下发酵3d、4d、5d、7d、14d,结果表明:复合真菌C在发酵7d、14d时,玉米秸秆饲料的粗蛋白质(CP)含量提高94.53%、106.19%(p<0.05),纤维组分含量显著下降(p<0.05);秸秆饲料的干物质(DM)48h瘤胃消失率无显著差异,而处理14 d的酸性洗涤纤维(ADF)瘤胃消失率显著高于7d处理的结果(p<0.05);用复合真菌C处理7d的玉米秸秆饲料饲喂肉用生长鹅,其日增重提高20.76%(p<0.05),料重比下降19.04%(p<0.01)。Corn stalks powder was mixed with 10% wheat bran and quantitative nutritional salt, the moisture content was adjusted to 70%, the compound eumycote composed of Geotrichum candidum, Candida parapsilosis, Trichoderma koningii and Trichoderrna viride ,at 30℃ and under oxygen condition fermented for3d, 4d, 5d, 7d, 14d. The results showed that when compoundeumycoteC fermented for 7-14d, the content of crude protein （CP） in corn stalks raised by 94.53%-106.19 % （p〈0.05）, the content of fiber declined significantly （p〈0.05） ;the 48h rumen disappearance rate of dry matter （DM） in corn stalks had no significant difference, but the rumen disappearance rate of ADF treated for 14d was significant higher than that treated for 7d （p〈0. 05） ;the goose was fed with the corn stalks treated with compound eumycote for 7d ,the daily body weight increase by 20.76%（p〈0.05） ,the ratio of feed to weight decrease by 19.04%（p〈0.01）o These results suggested that the corn stalks treated with compound eumycote is the biological active feed for unruminant, which is a new way to treat stalks by biology and utilization of it.
