Embodiment 2

[0037] Example 2 1. The difference from Implementation 1 is: in the preparation step, the preparation ratio is by weight percentage: 75% soybean polypeptide, 20% yeast hydrolyzed complex, and 5% compound probiotics.

Embodiment 3

[0038] Example 3 1. The difference from Implementation 1 is: In the preparation step, the preparation ratio is by weight percentage: 90% soybean polypeptide, 9% yeast hydrolyzed complex, and 1% compound probiotics.

[0039] The effect of the present invention is further described as follows in conjunction with technical scheme:

[0040] Selection of soybean meal raw materials: soybean meal raw materials come from grain and oil food processing enterprises, which meet the requirements of GB / T 19541-2004, but strict inspections must be carried out on soybean meal raw materials from different manufacturers and batches in order to adjust the appropriate fermentation Enzymatic hydrolysis process parameters.

[0041] A. Fermentation and enzymolysis of soybean polypeptide: deep fermentation of soybean meal by Bacillus subtilis, adding neutral protease at 100-200μ / g, material-to-water weight ratio 1:2-3, enzymolysis temperature 45-55℃, enzymolysis time 48- After 60 hours, the (TCA-NSI...

Abstract

This invention relates to a production method of a biological polypeptide used for feed, and the biological polypeptide can substitute for plasma protein in the feed. The biological polypeptide consists of: soybean polypeptides, a hydrolyzed yeast complex and a composite micro-ecological agent. The production method comprises the following steps: carrying out fermentation and enzymolysis on the soybean polypeptides, preparing the hydrolyzed yeast complex and preparing a product. The product obtained in the invention can completely substitute for the plasma protein in the suckling pig feed, provide high-quality protein ingredients for the feed, simultaneously improve piglet immunity, reduce piglet diarrhea, promote piglet growth, lower feed conversion and increase breeding benefits.

Description

technical field [0001] The invention relates to a production method of a biological polypeptide used for feed which 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...
