摘 要：筛选优良菌株，采用菜籽饼粕与酱油渣混合发酵生产蛋白饲料，克服了酱油渣单独发酵水分和食盐含量过大以及营养不全面的问题，有利于基质营养互补和发酵菌的生长繁殖，提高了菜籽饼粕脱毒率和饼粕、糟渣发酵饲料的粗蛋白增加率。2种物料按重量1：1混合，经曲霉菌在(30±2)℃下固态深层通风发酵24h，菜籽饼粕中的ITC(异硫氰酸酯)和OZT((口恶)唑烷硫酮)的总脱毒率可达89.8%，粗蛋白质提高16.9%，粗纤维下降，适口性改善。

ABSTRACT： The protein feed was produced from the mixture of rape cake and soy sauce residue through solid-state fermentation by excellent strains. This solved the problems of high moisture and solt content in the former fermentation of single soy sauce residue and the lack of some nutritious ingredients in the products. This was favorable for the complementation of basic nutrition and the growth of fermentation strains. Therefore,the detoxication of rape cake and the crude protein content in the fermented feed were improved.After the mixture of rape cake and soy sauce residue (1：1 ratio) with aspergillus was deeply fermented for 24 hours at (30±2)℃ temperature under aspirating condition,the detoxication rate of ITC (Isothiocyanate) and OZT(Oxazolidinethione) was up to 89.8%,and the crude protein content was increased by 16.9%,but the crude fiber content was decreased. However the palatability of the fermented feed was improved .
