Method for producing high-methionine and high-lysine feed by using composite bacteria fermented corn protein powder

Abstract

The invention discloses a method for producing high-methionine and high-lysine feed by using composite bacteria fermented corn protein powder, which comprises the following steps: preparing mixed bacterial solution of Corynebacterium, saccharomycetes and bacillus subtilis; and performing amplified fertilization, adding into a solid fermentation tank for further fermentation, drying, and crushing to obtain finished products. In the method, the processing cost is low, the operation is convenient, and the use of the corn protein powder fermented by mixed various bacteria and various trace elements as the raw materials improve the coarse protein and methionine and lysine content in the feed, improves the absorption effect of various organisms, and improves breeding benefits. Experiments prove the feed made by the method contains more than or equal to 40 percent of coarse protein, more than or equal to 8 percent of lysine, more than or equal to 9 percent of methionine, and that the feed satisfies the demands of animals for lysine, methionine and protein.

Description

[0001] technical field [0002] The invention relates to a method for producing high-methionine-lysine feed, in particular to a method for producing high-methionine-lysine feed by fermenting corn gluten powder with compound bacteria. Background technique [0003] With the continuous development of animal husbandry, people's demand for animal products has increased, and small-scale animal product production is far from meeting the growing needs of people. In the past, most animals were raised in free range or outdoors, and most animals were collected freely in the wild. Food, energy and crude protein intake cannot meet growth needs. Recently, with the vigorous development of animal husbandry and the popularization of various premixes and complete feeds, corn gluten meal is one of the commonly used raw materials in feed production. The method of producing feed from corn gluten powder has high processing cost and cumbersome process, and the content of methionine, lysine and cr...

Recently, with the vigorous development of animal husbandry and the popularization of various premixes and complete feeds, corn gluten meal is one of the commonly used raw materials in feed production. The method of producing feed from corn gluten powder has high processing cost and cumbersome process, and the content of methionine, lysine and crude protein in the feed produced by this method cannot meet the requirements, and it is not easy to be absorbed by animals, and the breeding benefit is low
