Method for producing seaweed protein feed through synergistic effect of enzymolysis and fermentation

The invention discloses a method for producing a seaweed protein feed through the synergistic effect of enzymolysis and fermentation. The method comprises the steps of fully mixing seaweed residue (the water content is 38%) and a feed enzyme preparation according to a certain proportion and performing the enzymolysis for 4-7h with the pH of 6.2-7.0 at the temperature being 35-45 DEG C to obtain a seaweed residue-feed enzyme preparation mixture; inoculating compound microorganisms and performing solid fermentation. The method has a simple process and is easy to operate; an external source is added to degrade a cellulose preparation to produce nutrition beneficial to microbial growth through the enzymolysis and make up the deficiency of enzyme produced by using the compound microorganisms, so as to stabilize the solid fermentation process and the product quality, greatly reduce the content of cellulose and increase the protein content; the seaweed protein feed is rich in multiple minerals, bioactive constituents and unknown somatomedin, and can be used as a protein feed for livestock and poultry and an aquatic feed; the method provides a technical support for growing tensions on developing novel protein resources and relieving a feed protein source.
