Problems solved by technology

[0003] Brewer's grains can be used to feed animals, but brewer's grains are unbalanced in nutrition, excessive in crude fiber, and low in limiting amino acids such as lysine and methionine, which do not fully meet the nutritional needs of farmed animals. applications are limited

Abstract

The invention discloses brewer's grain-mixed meal type biological fermentation feed used for fishes as well as a preparation method and an application thereof. The brewer's grain-mixed meal type biological fermentation feed for the fishes is prepared by the following steps: inoculating a fermentation agent into a fermentation raw material taking brewer's grains as a main component to obtain a fermentation system, and fermenting the fermentation system to obtain a fermentation product which is the biological fermentation feed for the fishes; the active ingredients of the leavening agent fermentation agent consist of lactobacillus acidophilus, bacillus subtilis and saccharomyces cerevisiae. According to the biological fermentation feed, the contents of crude protein, acid-soluble protein andrestrictive amino acid are increased, which is closer to amino acid balance, the nutritional structure is improved, and the nutritional value is improved, the obtained biological fermentation feed can improve the utilization rate of the feed, improve the growth performance of fishes and enhance the immunity of organisms, so that the culture benefit is increased, and the biological fermentation feed has a wide application prospect.

Description

technical field [0001] The invention relates to the field of biotechnology, a brewer's grain-miscellaneous dregs type bio-fermented feed for fish and its preparation method and application. Background technique [0002] Brewer's grains are the main by-products of the beer industry, with abundant sources and low prices. As early as 2012, the annual production of brewer's grains in my country has exceeded 10 million tons, and in recent years there has been an increasing trend year by year. The types of nutrients in brewer's grains are very rich and the content is considerable. It is composed of grain husk and seed coat, so it is rich in lignin, cellulose, hemicellulose, protein and lipids, of which hemicellulose is the main component of brewer's grains , the highest proportion can reach 40% of the dry weight of brewer's grains, followed by monosaccharides, mainly including glucose, xylose and arabinose. Brewer's grains contain 15% to 25% protein, mainly albumin, globulin, gl...
