Description

A kind of egg yolk flavor yeast polypeptides micelle feed and preparation method thereof

Technical field

The present invention relates to animal-breeding technical field, be specifically related to a kind of egg yolk flavor yeast polypeptides micelle feed and preparation method thereof.

Background technology

Yeast is a kind of unicellular fungi, can survive, belong to facultative anaerobe under aerobic and oxygen-free environment.Containing the trace element such as rich in protein, amino acid, nucleic acid, vitamin, digestive ferment and selenium, chromium, iron, zinc in yeast cells, wherein protein content accounts for dry cell weight 30%-50%.Yeast cell wall contains various bioactivators and polysaccharide.Yeast distribution is extensive, and its growth has procaryotic multiplication characteristic, can fast breeding, is conducive to the production cost of reduction industrial or agricultural.To take yeast as feed addictive that main body develops be a class Novel non-toxic, pollution-free, without the green bio feed addictive of hazard residue, effectively can improve gastrointestinal health of animals, strengthening animal immune level, reduce Animal stress, improve animal reproduction performance etc., to solution animal husbandry environmental issue, reduce antibiotic use, and obtain high-quality, safety animal product also significant.The primary product of past main some such as yeast single cell proteins or some vinasse class yeast of application processing in herding fishery or industry byproduct, but the main purpose of these products application alleviates feed protein resource contradiction in short supply, and these products due to limit by process technology at that time, level of processing is not high, palatability is also poor, and the utilization rate of feed is not high.In recent years, along with the development of China's scientific and technological level and going deep into animal microecology and Nutritional studies, exploitation palatability is better, utilization rate saccharomyces neoformans class feed addictive that is higher, that significantly can improve livestock and poultry and aquatic animal to grow reproductive performance has become feasible act.
