The invention discloses a corn cob
bacteria-
enzyme synergistic fermented feed suitable for feeding fattening pigs and a production process thereof. The process comprises the following steps of: 1) preparing the following
fermentation materials: 65-70% of corn cob, 1.5-2.5% of brown
sugar, 1.0-1.5% of composite multivitamins, 0.04-0.08% of NSP
enzyme and the balance of water; 2) dissolving the brown
sugar in the water to obtain brown
sugar water, weighing a composite
bacteria powder accounting for 2.0-2.5% of the total weight of the
fermentation materials, and then adding the composite bacteriapowder into the brown
sugar water to activate to obtain a mixed
bacteria solution, wherein the composite bacteria
powder consists of freeze-dried
lactic acid bacteria, freeze-dried
saccharomyces cerevisiae and freeze-dried
bacillus subtilis; and 3) uniformly mixing the corn cob, the composite multivitamins and the NSP
enzyme, filling the obtained mixture into a
fermentation device, inoculating the mixture with an activated mixed bacterial liquid, and carrying out closed fermentation to obtain the fermented feed. The process combines the advantages that beneficial microbial strains improve intestinal tract health and the NSP enzyme has good degradation effect on materials such as corn cob, carries out bacteria-enzyme synergistic fermentation on corn cob
waste material, prolongs the application industrial chain of waste materials of agricultural and sideline product such as corn cob, promotes the virtuous cycle of production, and has good application prospect.
