Corn cob bacteria-enzyme synergistic fermented feed suitable for feeding fattening pigs and production process thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to corn cob fungus enzyme synergistically fermented feed suitable for fattening pigs and a production process thereof. Background technique [0002] With the rapid development of the aquaculture industry, the shortage of protein feed in my country and the competition for food between humans and animals have become increasingly prominent. As one of the main feed crops, corn has been widely used in animal husbandry for a long time. my country's annual corn production is as high as 200 million tons, of which corncob production accounts for about 10%, reaching more than 20 million tons. Corn cob is the cob after the corn ear has been removed from the kernel. my country produces a large amount of corn cobs every year, but most of the corn cobs are burned as fuel in rural areas, resulting in a waste of resources. With the development of science and technology, the field of deep processing...

Problems solved by technology

Theoretically, multi-strain mixed fermentation can exert the fermentation characteristics of different strains, but there are still some problems to be solved in practical applications, such as: there may be antagonism between different strains, and the colonization effect of microorganisms on the wall of the gastrointestinal tract is not good. Stable, antagonistic when used together with antibiotics, easy inactivation of fermentation strains and difficult to maintain, unknown mechanism of action of microbial strains, difficulty in stabilizing the effect of microbial feed, use safety issues, etc.
