The invention relates to 
protein feed produced by multi-
fungus fermentation with 
steam explosion rapeseed meal and cotton 
meal and a method. 
Rapeseed meal and cotton meal are used as main materials, 
meat and bone meal, 
straw and 
pomace are used as auxiliary materials, and a group of oxic liquid strain and anaerobic liquid strain are inoculated, so the 
protein feed is obtained. The preparation method is as follows: raw materials are delivered to a 
steam explosion system to be exploded, and then are released to normal pressure quickly after 
steam explosion; the materials after steam explosion are delivered to 
chelation reaction granary and cooled to 30 DEG C, and then are sterilized by 
microwave. The sterilized materials are delivered to a 
fermentation granary and the group of the oxic liquid strain is inoculated at the same time, the inoculum concentration is 5 percent, the intermittent ventilation and 
oxygen supplying are performed, the oxic 
fermentation time is between 36 and 48 hours; after the oxic fermentation, an anaerobic strain is inoculated, the inoculum concentration is 5 percent, and the sealed anaerobic culture is performed; and when the peptides content reaches 3 percent, the fermentation ends. The 
protein feed produced by multi-
fungus fermentation with steam explosion 
rapeseed meal and cotton meal and the method have the advantages that 
toxin of miscellaneous mealis degraded completely after the steam explosion and 
microorganism fermentation treatment; the protein feed has 
flavor taste, and contains active substances, such as large amount of 
B vitamins, a plurality of vezyme and peptides, and so on; in addition, the protein feed has the functions of promoting 
growth development, resisting diseases.
