Problems solved by technology

[0003] Specifically, the moisture content of corn steep liquor is between 45-55%, the effective protein content is about 20% (accounting for about 40% of the total dry matter), and the fermentable sugar content is 5-7%; if according to these Active ingredients are used in the feed industry, and each ton of corn steep liquor is worth at least 1,000 yuan. However, because the composition of corn steep liquor is too complex, containing a large amount of inorganic salts (including sulfites), organic acids and various impurities, it is difficult to apply it to feed industry

Abstract

The invention discloses a fermented feed for laying hens as well as a preparation method and application of the fermented feed. The preparation method comprises the following steps: sequentially carrying out hydrogen peroxide oxidation and ammonia water pH adjustment on corn steep liquor, uniformly mixing the corn steep liquor with corn bran and wheat bran subjected to steam conditioning treatmentto obtain a raw material mixture, inoculating Baillard yeast and bacillus subtilis, performing aerobic fermentation, then inoculating streptococcus salivarius, performing anaerobic fermentation, andfinally, performing pneumatic drying to obtain the fermented feed. According to the preparation method of the fermented feed for the laying hens, hydrogen peroxide is adopted to treat the corn steep liquor, and sulfite in the corn steep liquor is oxidized, so that adverse effects on animal physiology are eliminated; the corn steep liquor is treated by adopting hydrogen peroxide and ammonia water,and the wheat bran after conditioning treatment with high-temperature steam is combined for use, so that the raw material mixture can be suitable for solid aerobic fermentation of Baillard yeast and bacillus subtilis; and a finished product obtained through combined fermentation of aerobic fermentation and anaerobic fermentation is a good laying hen feed raw material, so that the additional valueof corn starch byproducts is greatly improved, and obvious economic benefits and ecological benefits are realized.

Description

technical field [0001] The invention relates to the field of feed products, in particular to a fermented feed for laying hens and a preparation method and application thereof. Background technique [0002] According to statistics, the annual output of corn starch in China is about 25 million tons. Correspondingly, as a by-product of the production of corn starch, the annual output of corn bran is about 3.6 million tons, and the annual output of corn steep liquor is about 3.4 million tons; among them, corn The skin can be used in livestock and poultry breeding in a proportion of no more than 5.0wt%, on the premise that it does not affect the production performance of animals basically, while corn steep liquor is difficult to handle. [0003] Specifically, the moisture content of corn steep liquor is between 45-55%, the effective protein content is about 20% (accounting for about 40% of the total dry matter), and the fermentable sugar content is 5-7%; if according to these Ac...
