Embodiment example 1

[0026] Implementation case 1. Biopeptides that replace plasma proteins in feed. The range of components and percentages by weight is: soybean polypeptide 76-88%, yeast hydrolyzate 10-20%, and compound probiotics 1.2-6%; The soybean peptide is obtained by deeply fermenting soybean meal with Bacillus subtilis, and adding neutral protease after enzymolysis; the yeast hydrolysis complex is activated by adding water and sugar to the activated product, and then adding acetic acid Ethyl esters, and / or compound flavor enzymes, and finally heat-preserved and enzymatically hydrolyzed; the compound probiotics are selected from lactic acid bacteria, and / or yeast, and / or Bacillus licheniformis. The specific values ​​selected in this embodiment are: the biological polypeptides that replace plasma proteins in the feed, its components and percentages by weight are: 85% soybean polypeptides, 13% yeast hydrolyzed complexes, and 2% compound probiotics; The compound probiotics are lactic acid bac...

Embodiment example 2

[0027] Example 2. The difference from Example 1 above is that the biological polypeptides that replace the plasma proteins in the feed have components and percentages by weight: 76% soybean polypeptides, 20% yeast hydrolyzate, and 20% complex microecological compounds. Preparation 4%; the compound probiotics described in this example are yeast and Bacillus licheniformis.

Embodiment example 3

[0028] Example 3. The difference from Example 1 above is that the biological polypeptides that replace plasma proteins in the feed have components and percentages by weight: 88% soybean polypeptides, 10.8% yeast hydrolyzed complexes, and compound microecological Preparation 1.2%; the compound probiotics is yeast.

Abstract

The invention relates to a biological polypeptide capable of replacing plasma protein in a feed. The biological polypeptide comprises the following components: a soybean polypeptide, a yeast hydrolysis complex and a composite microecological preparation, wherein the soybean polypeptide is prepared by the steps of deeply fermenting soybean meal by bacillus subtilis, and then adding neutral protease and performing enzymolysis; the yeast hydrolysis complex is prepared by the steps of adding water and sugar into dry yeast used as a raw material, activating, then adding an additive into an activated substance, and finally preserving heat and enzymolyzing the activated substance; and the composite microecological preparation is lactic acid bacteria and/or saccharomycetes and/or Bacillus licheniformis. The product can completely replace the plasma protein in suckling pig feeds, provide a high-quality protein raw material for the feeds, and can improve the immunity of piglets, reduce diarrhea, promote growth, reduce feed conversion ratio, and increase breeding benefit at the same time.

Description

technical field [0001] The invention relates to a biological polypeptide that replaces plasma protein in feed, and belongs to the technical field of biological enzymolysis and fermentation. Background technique [0002] The safety issues of high-quality protein raw materials and the shortage of resources are important factors restricting the development of feed. It is of great significance to use modern biotechnology to develop high-quality plant-based protein and gradually replace animal protein. [0003] Plasma protein powder is a powder product made by spray-drying the blood plasma after separation of red blood cells from animal blood (usually pig blood or cow blood). Among them, it contains 78% crude protein, the digestibility is as high as 90%, and 7% lysine. The content of other amino acids is rich and balanced. It has the effect of preventing diarrhea and promoting growth of early weaned piglets, so it is widely used in the feed of weaned piglets, especially when th...
