Abstract

The invention discloses fermented soybean meal. The fermented soybean meal is prepared by fermenting soybean meal with bacillus subtilis, saccharomyces cerevisiae and enterococcus faecium, wherein the content of crude protein is higher than 55%, the content of glycinin is lower than 20mg/Kg, and the content of beta-conglycinin is lower than 30mg/Kg. The invention also provides a fermentation method of the soybean meal. The fermentation method comprises the following steps of (1) smashing the soybean meal into powder; (2) mixing bacillus subtilis seed fluid with saccharomyces cerevisiae seed fluid and enterococcus faecium seed fluid to obtain mixed fluid, compounding the mixed liquor with water so as to obtain fermentation liquor, and mixing the soybean meal powder with the fermentation liquor according to the feed liquor ratio being 1 to (0.5-1.5); (3) heaping the soybean meal which is inoculated and uniformly mixed so as to obtain a soybean meal fermentation heap, and sealing the soybean meal fermentation heap with a plastic cloth; and (4) performing fermentation for 3 days or more under the condition of 25-40 DEG C. The preparation method disclosed by the invention is simple and easy to operate and low in cost; the degradation rate of various anti-nutritional factors of the fermented soybean meal is high, the fermented soybean meal can be used for replacing raw materials for an animal-based protein feed, such as plasma protein and fish meal, can be used for replacing a part of micro-ecological viable bacteria preparations, and can be used for replacing organic acid partially, and the breeding economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a fermented soybean meal and its production method and its application in preparing pig compound feed. Background technique [0002] Soybean is an excellent vegetable protein resource, and the processed soybean meal is rich in essential amino acids. Crude protein can reach 43%-48%, and is rich in various amino acids, and is widely used in animal husbandry, especially lysine, which is easily lacking in other plant feeds, contains up to 215%-310%. It is a high-quality plant-based protein source that is widely used in the industry. However, because there are a large number of anti-nutritional factors in soybean meal, the direct use of soybean meal to feed livestock and poultry has a low protein biotransformation rate. Long-term use will cause poisoning symptoms such as indigestion and growth stagnation in animals, which affects the use value of soybean meal. In rec...
