Method for preparing fermenting feed by cassava vinasse

Abstract

The invention discloses a method for preparing fermenting feed by cassava vinasse. The method comprises the following steps of using cassava vinasse, soybean meal, converted mash, bran, lactobacillus, bacillus subtilis and wine brewing yeast as raw materials, uniformly mixing, loading into an anaerobic fermenting bag, and performing anaerobic fermenting at the temperature of 29 to 30 DEG C, so as to obtain the fermenting feed. The method has the beneficial effects that an effective path is provided for the functions of vigorously developing livestock industry, solving problem of reutilization of waste residues in an alcohol production process, improving agricultural ecological environment, reducing pollution to environment, and promoting adjusting of agricultural industry structure; the significant economic benefit and social benefit are realized.

Description

technical field [0001] The invention belongs to the technical field of fermented feed, in particular to a method for preparing fermented feed from cassava distiller's grains. Background technique [0002] Microbial feed additives are a new generation of environmentally friendly feed. In 2008, the State Science and Technology Commission joined hands with China Agricultural University, Beijing Institute of Agricultural Science and Animal Husbandry and other professional institutions to tackle key problems, and achieved certain technological breakthroughs. Microbial feed additives can competitively regulate the flora structure in the host, activate the immune system, improve the intestinal environment of animals and Reduce pollution etc. At present, cassava is fermented with ethanol, and the cassava distiller's grains produced are mainly added to boilers for blending, and the economic benefits produced are very limited. Fermenting cassava distiller's grains to produce microbi...

AI Technical Summary

Problems solved by technology

[0004] At present, the utilization rate of cassava distiller's grains in the alcohol production process is low, and only a small part is used for fuel, feed, agricultural fertilizer, papermaking, culture medium for edible fungi, biogas production, etc., and most of them are not fully utilized, which not only causes resources waste and pollute the environment

There are also some researches on the deep processing of cassava residues at present, but strictly speaking, the current technology is not perfect, and the main problems of the prior art are: (1) the utilization rate of the cassava residues in the alcohol production process is low, increasing environmental pollution load

(2) The cost of cassava slag after drying is relatively high, which is not an ideal way of resource utilization

(3) Due to the low crude protein and high crude fiber in cassava waste residue, it is difficult to meet the needs of feed nutrition by direct utilization

However, there are still deficiencies in the development of production strains, the degradation and utilization of cellulose and hemicellulose in cassava residues, and the matching production process.

[0005] In short, the utilization rate of cassava residue resources is still very low at present, so it is urgent to introduce an ideal process for cassava residue processing, improve the quality of cassava residue protein feed, and solve the problem of low utilization rate of cassava residue
