Micro-ecology fermentation protein feedstuff and preparation method thereof

Abstract

The invention provides a micro-ecological fermented protein feed and a preparation method, wherein the feed is prepared by mixing bean pulp and silkworms with quality ratio 90-98:2-10, then cooking to obtain solid state fermention medium, then inoculating mixed strains of bacillus subtilis, Saccharomyces cerevisiae, lactobacillus and Rhizopusoligosporus on solid fermention medium, then co-mixing for 30-45 hours at 33-37 DEG C, drying fermentation products after completing fermenting, crushing and obtaining the micro-ecological fermented protein feed. The inventive micro-ecological fermented protein feed contains a plurality of biological active peptides, content of small peptide reach more than 22%, which is favourable for digestion and development; contains lactobacillus, microzyme, which is favourable for controlling useful microbiological population in intestinal tracts of animals; has good delicious flavor and good luring effect, advances young animals for ingestion; contains soybean isoflavone more than 0.05%, markedly increases immunity of bodies, increases producibility of animals; relieving odmour of fecal waste; fully takes place of animal protein feed of fish meal and plasma protein flour and the like.

Description

(1) Technical field [0001] The invention relates to a micro-ecological fermented protein feed and a preparation method thereof. (2) Background technology [0002] The issue of "promoting the growth of young animals" has always been the focus of attention of breeding scientific and technological workers. In order to meet the special physiological growth needs of young animals, feed formulators often add a large amount of food that is similar to the source of the mother or is easy to digest and absorb. Raw materials, such as fish meal, meat and bone meal, plasma protein powder, whey powder, etc. However, the application of these raw materials makes the price of formula feed higher, which affects the benefits of the aquaculture industry. It is also because fishmeal, as a sub-scarce resource, has been strictly limited in production in major producing countries. Banned due to safety concerns. The limited use of animal protein feed and the increasing demand for high-quality feed...

AI Technical Summary

Problems solved by technology

Many people have done a lot of work in this regard, such as using physical methods, chemical methods, biological breeding methods, etc. to eliminate or reduce the anti-nutritional factors in soybean meal. Although these methods have certain effects, they have high costs or residual chemical reagents , or destroy some nutrients or still have many anti-nutritional factors. In addition, there is also a lack of potential specific bioactive peptides after digestion of animal protein, so it has not been well applied.
