Description
Technical field
The present invention relates to a kind of method producing high protein feed for raw material secondary mixed fungus fermentation with distiller's grains of beer, belong to feedstuff
Manufacture field.
Background technology
In recent years, the method for domestic and international commonly used drying preserves distiller's grains of beer, although efficiently solve distiller's grains of beer easy
Corrupt problem, reduces environmental pollution, simultaneously facilitates accumulating.But owing to the crude fiber content in distiller's grains of beer is too high, animal is agreeable to the taste
Property poor, use that face is little, the market price is the highest, add the factors such as equipment investment, artificial and energy consumption, occur in that to sell fresh grain more dry than selling
The situation that grain is also made money, some beer company occurs that drying plant leaves unused.
Distiller's grains of beer are directly as feedstuff, the always hot issue of research.Deng Qihua[1]Distiller's grains of beer are produced pig feed close
Key technology is studied, and uses preconditioning technique, enzymolysis and the fiber content of probiotics fermention technology degraded distiller's grains of beer, improves
Protein quality, improves the Feeding Value of distiller's grains of beer.So that sugar is poor and distiller's grains of beer are as raw material, access yeast[2], many bacterial strains optimization group
Close such as bacillus subtilis, candida tropicalis solid state process fermenting and producing high protein feed[3-6], and containing multiple digestive enzyme.Profit
With Response surface methodology, the condition that optimization distiller's grains of beer solid fermentation is prepared albumen feedstuff is further studied[7]。
Sun Danfeng[8]Carrying out the feeding experiment such as pig, chicken Deng to fermented brewer's grain feedstuff, result shows respond well.
At present, there are no distiller's grains of beer secondary mixed fungus fermentation technology and produce the relevant report of high protein distiller's grains of beer feedstuff.
