Abstract

The invention discloses a corn stalk-soybean meal mixed fermented material, its preparation method and application, and belongs to the technical field of biological fermentation. The corn stalk-soybean meal mixed fermented material of the present invention is prepared by enzymatic hydrolysis and secondary fermentation after mixing fermented corn stalk, corn flour and fermented soybean meal according to the weight ratio of 1-6:0.5-3:2-12; The fermented corn stalks are fermented by Zizhi solid. The corn stalk-soybean meal mixed fermentation material prepared by the invention has high nutrient content, can not only improve the growth performance of animals, but also improve gastrointestinal digestion function, improve the antioxidant performance of the body, and enhance immunity.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a corn stalk-soybean meal mixed fermentation material, a preparation method and application thereof. Background technique [0002] Crop straw is an auxiliary product of agricultural production, which has not been fully and effectively utilized in our country. Traditional planting habits usually return a large amount of crop straw directly to the field, discard it, or even burn it, which not only pollutes the environment and affects the construction of a harmonious society, but also causes the economic value of the straw to be lost. [0003] Corn stalks contain more than 30% carbohydrates, 2%-4% protein and 0.5%-1% fat; among them, the content of ineffective crude fiber is high, the content of crude protein is low, and the nutrition is low. It needs to be treated before feeding animal. [0004] Soybean cake is a plant-based protein material with high ...
