Functional biological feed production process

Abstract

The present invention partially enzymatically hydrolyzes feed materials such as corn and soybean meal, wherein 1 / 3 of the protein is enzymolyzed into small peptides, more than half of the starch is degraded into monosaccharides such as fructose and glucose, and both small peptides and monosaccharides can be directly digested by the animal. Absorb and utilize. In the prepared feed, the resistance factors urease, pectin, phytic acid, and cellulose are reduced by about 70% respectively, and the soybean protein allergens 7S and 11S globulin are reduced by about 50%. Feed, aquaculture bait and source of nutrition for pregnant and lactating animals. The biological feed prepared by the invention has the advantages of easy absorption, reduced animal diarrhea rate and improved palatability, simple production process, less investment and low cost, and is suitable for large-scale production and popularization.

Description

technical field [0001] The patent of the invention relates to a preparation method of a novel functional biological feed, which belongs to the field of animal feed. Background technique [0002] At present, the protein in the feed is mainly plant protein, which has a large molecular weight, usually tens of thousands to hundreds of thousands, and is not easy to be completely digested and absorbed by the digestive organs of animals, especially the digestive organs of young poultry and livestock are not yet perfect, so it is more difficult to digest and absorb protein. For example, the 7S and 11S globulins in soybean meal protein can easily cause allergic reactions in the digestive tract of pigs and cause diarrhea (Yao Kun et al., 2011; Liu Haiyan et al., 2011; Chen Zhongping, 2011); the digestive tract of aquaculture animals is shorter than that of mammals, and is less sensitive to protein. Digestion and absorption are even more incomplete, and most of the latter are excreted ...

AI Technical Summary

Problems solved by technology

[0008] 3. Although microbial fermentation of soybean meal can partially degrade soybean protein into polypeptides and small peptides, and can degrade some nutritional resistance factors, there are also obvious shortcomings

[0009] (1) The production cycle is long, plus the time required for strain preparation, the entire production cycle is 4-5 days;

[0010] (2) It occupies a large area. Fermented soybean meal is usually fermented in cement ponds. If one batch is fed per day, 4-5 large cement ponds are required; if two batches are fed per day, 8-10 large cement ponds are required.

[0011] (3) High labor intensity and low production efficiency;

[0012] (4) Substrate and energy are consumed during the growth and reproduction of microorganisms, resulting in a waste of resources
