What are the roles of microbial fermentation feed?

The role of microbial fermentation feed is mainly reflected in two aspects, one is the use of cheap agricultural and light industry by-products to produce high-quality feed protein raw materials, and the other is to obtain high activity of beneficial microorganismsThe application of these microbial products, on the one hand, can improve the conversion rate of feed and promote the growth of livestock and poultry, on the other hand, it can regulate the micro-ecological balance of animals and improve the health of animalsThere are also live bacteria that can be used to treat animal diseasesThe application of microbial fermentation feed in aquatic animal breeding can reduce the use of antibiotics, help the production of safe food, improve the competitiveness of product exportsfirst, supplement beneficial bacteria, regulate the micro-ecological balance of animalshealthy animals in the intestines of a variety of microbial communities, interdependent and mutual constraints between various microbiomes, constitute the balance of micro-ecosystems in the intestines of livestock and poultry, the establishment of a normal and well-balanced intestinal microbiome system to resist pathogenic microbial infection is of great significanceBecause of the interaction between microorganisms, existing microorganisms in an ecosystem prevent the invasion of new organisms in this area, and beneficial bacteria use competitive inhibition to prevent harmful microorganisms from adhering to and multiplying in the intestinal mucosaTherefore, it is very important to take microbial feed in animals whose flora is slow or has obstaclesFor adult animals, since many microorganisms can only survive in the intestines for a considerable period of time, live bacterial preparations must be taken continuously to maintain the implantation of a particular microorganism in the intestinessecond, chemical barrierthrough beneficial microorganisms such as lactic acid bacteria produced organic acids (lactic acid, acetic acid, acetic acid) to reduce the pH in the digestive tract, inhibit the growth of other pathogenic microorganisms, environmental pH of 4 o'clock Ecoli and salmonella can not multiply, played a role in maintaining the balance of intestinal flora to promote growth, while the acidic environment in the digestive tract to promote the absorption of mineral elements calcium, phosphorus, iron and vitamin Dthird, produce beneficial metabolites, inhibit and kill harmful bacteriabeneficial microorganisms can produce peptide bacteria, enzymes and small amounts of inorganic substances, can inhibit the growth of harmful bacteria or prevent the adhesion and invasion of harmful mycotoxins in epithelial cellsLactobacillus and Streptococcus aureus peptides such as Lactobacillus and Streptococcus can inhibit the growth of salmonella, Shigella, Bacillus LColiandeur and Ecoli; fourth, has a nutritional effect, promotes animal growth microbial fermentation feed beneficial bacteria itself is a high-protein substance, while metabolism in the animal intestines can produce a variety of beneficial causes that help the animal's nutritional digestion, thereby promoting the growth and development of aquatic animals and weight gain Enzymes, lipases, etc.) promote the digestion and absorption of nutrients, yeast can produce amino acids, multivitamins (K, C, B1, B2, pantonic acid, niacin, biotin, inositol and folic acid, etc.) for animal use, yeast can also promote the production of phytase, improve the utilization of phosphorus fifth, prevent the production of harmful substances microbial fermentation feed to promote the digestion and absorption of camp substances, reduce the production of ammonia and other corrupt substances The research shows that feeding microbial fermentation feed can reduce the content of ammonia in the contents, feces, venous veins and the content of the intestinal content of lithofol, pyridoxine, 3-methyl pyridine and other corrupt substances, reduce the odor of feces, purify the environment sixth, improve the body's immune function beneficial microorganisms in fermented feed can be used as a non-specific immunomodulator, through the bacteria itself or cell wall composition to stimulate and activate the host immune cells, promote phagocytosis cell vitality or act as an adjumate Beneficial microorganisms can also perform specific immune functions to enhance the ability of B-cells in animals to produce antibodies Direct feeding microorganisms prevent the occurrence of disease by promoting the body to develop body fluid immunity and cell immunity, improve the level of antibodies in livestock and poultry, enhance immune function, and kill pathogenic bacteria that invade the body of the machine in a timely manner Experiments have found that Lactobacillus can enhance the body's immunity, some probiotics can affect the body's immune system's ability to respond, its ability to affect the bacteria vary
