Method for producing feed additive by fermenting corn bran and corn grit, additive and application

Abstract

The invention belongs to the technical field of fermented feed additives, and particularly relates to a method for producing a feed additive by fermenting corn husks and corn grits.The method comprises the steps that firstly, the corn husks and the corn grits.The corn husks and the corn gritsare smashed and sieved to obtain raw material particles with uniform particle size, then nutrient substances and water are added, and pH is adjusted to obtain a fermentation substrate; adding a compound enzyme for treatment to obtain a fermentation culture medium, separating to obtain a liquid fermentation culture medium and a solid fermentation culture medium, respectively treating the liquid fermentation culture medium and the solid fermentation culture medium, and uniformly spraying the liquid fermentation culture medium inoculated with edible saccharomycetes on the dry solid fermentation culture medium to obtain a fermentation substrate; and finally, fermenting, drying and granulating under a constant-temperature condition to obtain the feed additive. The invention also provides the additive prepared by the method and application of the additive. Comprehensive utilization of the corn bran and the corn grit is promoted, the fermentation efficiency is high, and the production period can be shortened, so that resources and cost are saved, and the obtained additive is beneficial to absorption.

Description

technical field [0001] The invention belongs to the technical field of fermented feed additives, and in particular relates to a method, an additive and an application for producing feed additives by fermentation of corn husks and corn residue. Background technique [0002] Corn husks and corn dregs are by-products produced after deep processing of corn. The main components are fiber, starch, protein, etc., and have a large amount of nutrients. If they are discarded in large quantities, it will not only cause energy waste, but also lead to bacterial growth and environmental pollution. However, after proper treatment of corn husk and corn dregs, their internal nutrients can still be widely absorbed, so corn husk and corn dregs can be used as raw materials for the feed industry. [0003] The traditional method is to enzymolyze the residue, inoculate Bacillus subtilis and lactic acid bacteria, and dry it after airtight fermentation to obtain microecological fermented feed. As s...

[0003] The traditional method is to enzymatically hydrolyze the residue, inoculate Bacillus subtilis and lactic acid bacteria, and dry after airtight fermentation to obtain microecological fermented feed. As described in "The method", the obtained micro-ecological feed raw materials have high protein content and high content of beneficial viable bacteria, which can improve the intestinal flora of animals, improve the immunity of animals, and at the same time turn waste into treasure and solve the problem of solve the current food security and environmental pollution problems, but the overall steps are too simple, and the production cycle is long and the production efficiency is low
