Production method of high-protein feed containing arginine

Abstract

The invention discloses a production method of high-protein feed containing arginine. The production method comprises the following steps: performing liquid fermentation with corynebacterium glutamicum, candida utilis, lactobacillus plantarum and bacillus natto; mixing fermented mash rich in metabolic products with mash rich in thalluses, then mixing the mixture with soybean meal and the like in proportion, and performing solid state fermentation; finally drying products, and packaging the dried products so as to obtain final products containing crude protein of which the content is higher than 50% and arginine of which the content is higher than 4.0%. The production method disclosed by the invention has the advantages that the technology is simple, mixed fermentation is directly performed on the fermented mash and solid materials, the microbial metabolism product namely the arginine is utilized, so that the time of the solid state fermentation is greatly shortened, and the probability of infectious microbes infection in the solid state fermentation process of raw materials is reduced; the energy consumption is low, and waste is not discharged in the fermentation process; according to feed raw materials prepared by the production method, the content of anti-nutritional factors in a plant meal group is reduced, the content of the arginine is higher than 4.0%, the additive amount of exogenous arginine can be reduced or replaced, and the cost of the feed is reduced.

Description

technical field [0001] The invention relates to the field of feed production, in particular to a method for producing high-protein feed rich in arginine. Background technique [0002] Agricultural and sideline products such as soybean meal, cotton meal and peanut meal have a large output in the grain and oil industry, and are generally used as protein raw materials for animal feed, and are widely used in feed processing, livestock and poultry, and aquaculture industries. However, this kind of cake belongs to vegetable protein and contains a large number of anti-nutritional factors, such as trypsin inhibitors, soybean antigenic protein, uric acid, plant lectins, non-starch polysaccharides, etc., which affect the digestion and absorption of feed by animals. Therefore, in production, it is necessary to effectively remove anti-nutritional factors in cakes and improve feed utilization; , a low-cost substitute for high-quality feed protein raw materials. High-quality feed prote...

Problems solved by technology

Their shortage limits the utilization of other amino acids in the diet in livestock and poultry, reducing the nutritional value of the protein in the whole diet

[0003] Arginine is also known as a semi-essential amino acid. Although it can be synthesized endogenously through the decomposition of protein in the animal body or the conversion of other amino acids (glutamic acid and citrulline, etc.) in the body, the amount of synthesis usually cannot meet the normal physiological needs of the animal body. Or mainly rely on the animal to absorb from the basal diet

When arginine is lacking in the diet, it can cause animal weight loss, low feed conversion efficiency, etc.

The content of arginine in agricultural and sideline products such as soybean meal is low, which cannot meet the needs of normal growth of animals, and must be added from an external source

[0004] Microorganisms such as bacillus, yeast, and lactic acid bacteria can directly ferment agricultural and sideline products such as soybean meal. Although it can eliminate the anti-nutritional factors of soybean meal and improve the digestibility, for example, the national patent (application publication number: CN102406134A) discloses a fermented soybean meal with high digestibility solid-state fermentation methods, but it is difficult to increase the content of arginine in the fermented protein feed produced by these methods. Up to now, there is no high-quality feed protein raw material product rich in arginine in the market
