Problems solved by technology

However, there are not many studies on fermented soybean hulls in the market, and the fermentation technology is not mature enough. Although some people still try to use single bacteria or composite bacteria to ferment, there are problems such as poor feed conversion rate and unstable product quality. As a result, the large-scale promotion of this technology in the field of fermented feed is limited to a certain extent
In addition, aerobic fermentation is mostly used in fermented feed in my country, which has a high risk of mold contamination, limited fermentation effect, and problems such as moldy deterioration and short storage time.

Abstract

The invention discloses a high-dietary-fiber low-antigen-protein fermented soybean hull and a preparation method thereof. The high-dietary-fiber low-antigen-protein fermented soybean hull is obtainedthrough the segmented fermentation of soybean hulls, leavening agents and distilled water, and the proportion of the soybean hulls, the leavening agents and the distilled water is 50-66 parts of soybean hulls, 5.5-20 parts of leavening agents and 25-40 parts of distilled water. The high-dietary-fiber low-antigen-protein fermented soybean hull has high contents of dietary fibers and organic acids and a large beneficial viable count. Meanwhile, by use of the invention, various antinutritional factors (soybean antigen protein, bad oligosaccharide, urease and the like) in the soybean hull can be removed to a large extent, the flavor and the palatability of the fermented soybean hull are effectively improved, the cost of a feed is lowered, the nutritional value and the feeding value of the soybean hull are improved, and the use ratio of a soybean byproduct is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to fermented soybean hulls with high dietary fiber and low antigenic protein and a preparation method thereof. Background technique [0002] In recent years, the research and application of dietary fiber has become a hot spot both at home and abroad. Studies have shown that dietary fiber diets have different nutritional effects on animals at different growth stages, and can solve some nutritional problems of animals at different growth stages, such as diarrhea in piglets and constipation in sows. my country is rich in unconventional feed resources, but the unconventional feed resources rich in dietary fiber are not fully utilized in my country at present, which not only causes waste of feed resources, but also pollutes the environment. [0003] Soybean hulls are a new type of dietary fiber feed material, which has the advantages of high crude fiber conte...
