Embodiment 1

[0031] Take a certain amount of fresh chicken liver or frozen chicken liver (frozen chicken liver needs to be thawed), mince it and grind it into a puree, stir it evenly, seal it and boil it for 30 minutes, add 500U / g compound protease after cooling down, keep it at 50°C for 6 hours . After enzymatic hydrolysis, the sample and dry material were mixed at a ratio of 1:2.5 (dry material: crushed corn 65%, soybean meal 10%, rapeseed meal 5%, bran 20%), and then added 1.5×10 6 cfu / g lactic acid bacteria, 1×10 6 cfu / g yeast, 1.5×10 7 cfu / g compound bacillus and 300 U / g compound protease were thoroughly mixed and cultured at 37°C for 4 days to obtain sample 1.

Embodiment 2

[0033] Take a certain amount of fresh duck intestines or frozen duck intestines (frozen duck intestines need to be thawed), grind them into a puree, stir well, seal and boil for 30 minutes, add 400U / g compound protease after cooling down, and keep warm at 50°C for 6 hours . After enzymatic hydrolysis, the sample and dry material were mixed in a ratio of 1:1.5 (dry material: crushed corn 65%, soybean meal 10%, rapeseed meal 5%, bran 20%), and then added 1×10 6 cfu / g lactic acid bacteria, 1.5×10 6 cfu / g yeast, 1.5×10 7 cfu / g compound bacillus and 200 U / g compound protease were thoroughly mixed and cultured at 37°C for 4 days to obtain sample 2.

Embodiment 3

[0035] Take a certain amount of frozen chicken waste (chicken liver, chicken intestines), thaw it, mince it and grind it into a puree, stir it evenly, seal it and boil it for 30 minutes, add 450U / g compound protease after cooling down, and keep it at 50°C for 6 hours for enzymatic hydrolysis. After enzymatic hydrolysis, the sample and dry material were mixed in a ratio of 1:2 (dry material: crushed corn 65%, soybean meal 10%, rapeseed meal 5%, bran 20%), and then added 1×10 6 cfu / g lactic acid bacteria, 1×10 6 cfu / g yeast, 1×10 7 cfu / g compound bacillus and 250 U / g compound protease were thoroughly mixed and cultured at 37°C for 4 days to obtain sample 3.

Abstract

The invention provides an animal protein enzymolysis and vegetable protein fermentation linked feed preparation method. The method comprises the following steps: performing enzymolysis on an animal protein source to obtain a component A; crushing a vegetable protein source to obtain a component B; mixing the component A with the component B to obtain a component C; mixing the component C with a bacterial enzyme preparation to obtain a component D; and and culturing the component D into a constant-temperature box, thereby obtaining a required feed. According to the feed preparation method provided by the invention, through linkage of animal protein enzymolysis and vegetable protein fermentation, proteins from different sources are utilized, the content of substances easy to digest and absorb such as small peptides and amino acids is increased through the animal protein enzymolysis, digestion and absorption are accelerated; then linked fermentation with vegetable proteins is performed, rich bioactive substances such as enzymes and probiotics are added, so that the nutritional value of the vegetable proteins is increased, an intestinal flora structure of an animal can be improved, the immunity of the animal can be improved; and meanwhile, anti-nutritional factors in a vegetable protein raw material can be significantly removed.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to a feed preparation method in which animal protein enzymatic hydrolysis and plant protein fermentation are linked. Background technique [0002] Protein is the main nutrient for the growth and production of livestock, poultry and aquatic organisms. With the continuous advancement of modern feed processing technology, the source of protein required by animals has become more and more extensive from the traditional single form. The requirements for protein feed are getting higher and higher, and the demand is also increasing. For this reason, the breeding and industrial circles have begun to look for and study new protein feed resources. [0003] Animal protein comes from the by-products of livestock, poultry and aquatic product processing and animal protein sources. It contains sufficient protein, vitamins and minerals, but has a high fat content and is easy to oxidize a...
