Abstract

The invention discloses a method for producing high-efficiency protein feed by synergizing bacillus coagulans with feed enzymes, and belongs to the field of biotechnology fermentation. The present invention utilizes bacterial enzymes to synergistically process the soybean meal, does not need to sterilize the soybean meal, has facultative anaerobic and anaerobic fermentation in the whole process, and has low energy consumption and low dry matter loss. The technological process of the invention is simple and convenient to operate, and is suitable for both direct production and feeding in farms and large-scale production in feed mills, and the cost of raw materials is low, so it is suitable for industrialized production. The fermented soybean meal of the invention has strong sour flavor and strong palatability. The pH is between 3.2 and 4.5, and the organic acid content is above 2.8%. The acid-soluble protein is more than 6.5 times higher than that before fermentation, and the relative molecular weight of soluble protein is within 500, accounting for more than 60%. The urease activity is lower than 0.073U / g, and the raffinose content is low. At 0.42%, stachyose is less than 0.035%; the number of spores of lactic acid bacteria coagulans reaches 2.0×10 9 More than cfu / g.

Description

technical field [0001] The invention belongs to the field of biotechnology fermentation, and in particular relates to a method for producing high-efficiency protein feed by cooperating with bacillus coagulans with feed enzymes. Background technique [0002] The absorption of macromolecular proteins by animals is obviously not as good as the absorption of small molecular polypeptides and amino acids. At the same time, there are many anti-nutritional factors in plant protein raw materials, such as urease, trypsin inhibitor, phytic acid, lectin, lipoxygenase and Soybean antigenic protein, etc. affect the digestion, absorption and metabolism of nutrients, and have adverse effects on the health and production performance of animals, thus restricting the more effective application of plant protein in poultry breeding. [0003] The current methods for producing high-efficiency biological protein feed mainly include protease hydrolysis and microbial degradation. [0004] The use of...
