Composite biological protein feed stuff and manufacture method thereof

Abstract

The invention discloses compound biological protein feed and a preparation method thereof. The protein feed is made by mixing and stirring the following materials with microbial strains, fermenting, baking and crushing. The feed comprises the following materials by the weight percentages as follows: chaff 30%-55%, rice pericarp 3%-15%, and edible mushroom leftover germ bran 40%-60%. The weight ratio of the materials to the microbial strains is (90-95):(5-15). In the invention, the chaff, the edible mushroom leftover germ bran and the rice pericarp are complexly fermented to complement each other's advantages, xylogen and cellulose are degraded by 70% or so, mycoprotein is increased by 25-28%, thereby meeting the quality requirement for grain feed, and meanwhile increasing diseases suppressing and growth promoting factors, such as various vitamins, minerals, and a plurality of organized enzymes. Therefore, the protein feed is safe and environment-friendly, and can meet the growth and development requirements of livestock and poultry without addition of grain for energy.

Description

Technical field: [0001] The invention relates to feed, in particular to biological protein feed in livestock and poultry feed. technical background: [0002] my country is a big country of rice production. In the process of processing, about 30% of the total amount of rice bran should be produced, because most of it is lignin and cellulose, and the content of protein and vitamins is very small or even zero. Therefore, Only a small part of these bran is used for wine making, and the rest are all left to rot as waste, which not only wastes resources, but also pollutes the environment. In the patent application "Microorganism Multifunctional Health Nutrition Rice" (Application No.: 2008100203405) submitted by the inventor, the lignin and cellulose in the rice husk were decomposed by 30-40%, and the vitamin and protein increased to 6 -8% (the protein it contains is close to 1 / 2 of the wheat bran content), but this chaff has not been well utilized, and it is a pity to discard it....

Problems solved by technology

[0002] my country is a big country of rice production. In the process of processing, about 30% of the total amount of rice bran should be produced, because most of it is lignin and cellulose, and the content of protein and vitamins is very small or even zero. Therefore, Only a small part of the bran is used for wine making, and the rest are left to rot as waste, which not only wastes resources, but also pollutes the environment.

In the patent application "Microorganism Multifunctional Health Nutrition Rice" (Application No.: 2008100203405) submitted by the inventor, the lignin and cellulose in the rice husk were decomposed by 30-40%, and the vitamin and protein increased to 6 -8% (the protein it contains is close to 1 / 2 of the content of wheat bran), but this kind of chaff has not been well utilized, and it is a pity to throw it away

[0003] There are also crop straws: such as corn stalks, corncobs, bean straws, cottonseed hulls, peanut shells, etc., which are used as raw materials for edible fungi after being crushed and matched. Half of the enzymatic hydrolysis, a large amount of mycoprotein remains in it, but it has not been well utilized

[0004] Whether it is the rice bran obtained by the inventor in the "microbial multifunctional health-care nutrition rice" or the mushroom bran leftovers of edible fungi, the main reason why it is not used is that the cellulose content is still high, the protein content is still low, and Incomplete nutrition, poor palatability
