Peptide protein feed and preparation method thereof

Abstract

The invention relates to a peptide protein feed which includes: feed cake meal, fermented bacterial liquid, mannase, xylanase, cellulase, dextranase, molasses and water. A preparation method includes the steps of: (S1) preparing lactic acid bacteria liquid and yeast liquid; (S2) performing stacking fermentation to the raw materials; and (S3) drying and crushing the fermented raw materials and packaging the raw materials to obtain the peptide protein feed. The peptide protein feed is reduced in production cost, is effectively increased in contents of small peptides and organic acids and degradation quantity of anti-nutritional factors, is improved in palatability and is increased in intake, can reduce stinky smell of feeding animals and reduce defecation, improves digestion and absorption, increases production benefit and is green and environment-friendly.

Description

Technical field [0001] The present invention relates to the technical field of animal feed, in particular to a feed related to peptide protein and its preparation process. Background technique [0002] As we all know, my country's fishery resources are scarce, fishmeal production is insufficient, and quality deviations. As far as high-end feed ingredients are concerned, my country needs to import a large amount of fishmeal and whey protein powder every year; coupled with animal-derived products, there are certain safety risks. Therefore, the state prohibits the use of animal-derived feed products such as fish meal and blood meal in dairy production. Therefore, how to develop alternative products for fish meal and whey protein powder has become an urgent issue for China's feed and food industries. [0003] Vegetable meal is the most commonly used protein material, because soybean meal contains trypsin inhibitors, non-starch polysaccharides (xylan, mannan, α-galactose, dextran, etc....

AI Technical Summary

Problems solved by technology

[0006] 1. Large investment, high cost (especially the high cost of the drying process), and the requirement of raw materials with high basic protein content, resulting in high sales prices of small peptides, it is very difficult to promote and use, and there are few livestock breeding industries at present. Use small peptide protein feed;

[0007] 2. The solid enzymatic hydrolysis production method adopts anaerobic fermentation, the protein decomposition is poor, the small peptide protein content is rarely increased, and the anti-nutritional factors are less degraded, and the fermentation effect is not obvious, which leads to the limitation of the application of the prepared small peptide protein feed

[0008] 3. The solid enzymatic hydrolysis production method adopts aerobic fermentation, which requires large investment, high cost, little increase in small peptide content, and poor palatability, which limits the application of the prepared small peptide protein feed.
