Abstract: The present invention belongs to the technical field of biological fermented feeds, in particular to a two-step production method of a mycoprotein biological feed by fermenting corn husks. The present invention provides a preparation method for a mycoprotein biological feed, which comprises: inoculating Aspergillus niger microbial agent on a first fermentation substrate for first fermentation, to obtain a yeast seed; and inoculating a compound microbial agent in a second fermentation substrate to perform second fermentation. The compositions of the first fermentation substrate, the second fermentation substrate and the compound microbial agent are defined. The degradation of cellulose and hemicellulose in the corn husk raw material can be maximized and the protein content is increased through two fermentations, while taking into account the cost. A preparation method of the high-quality protein feed is provided for the feed industry.
