As the saying goes, "livestock and poultry breeding is to raise the intestine", the most important thing affecting the function of the intestine is the intestinal microorganisms, so "raising the intestine is to raise microorganisms", the anaerobic microorganisms in the posterior intestinal segment decompose the undigested fibers, semi-fibers, polysaccharides and other substances in the feed into short-chain fatty acids, so "the essence of raising microorganisms is to raise short-chain fatty acids (SCFA)". The four major functions of the intestine: digestion, immunity, microbial flora, the second brain; after the feed ban, probiotics, probiotics, plant essential oils and enzyme preparations are considered to be effective countermeasures, they will affect the intestinal microbial flora, and the final metabolites are realized through short-chain fatty acids (SCFA), undigested proteins and fats are converted into polyamines, lipopolysaccharides and other harmful substances in the back intestine; undigested carbohydrates are used by microorganisms in the post-intestinal tract to produce short-chain fatty acids. The core of short-chain fatty acids is butyric acid, so the antibody can not go around the core component - butyric acid. At present, the industrial production microorganisms that can metabolize and produce butyric acid in the animal intestine are mainly Clostridium butyrate.

Function of Clostridium butyrate
1. Powerful intestinal integrity
In terms of quantity and type, it supplements the normal flora lacking in the intestine, adjusts the balance of intestinal colonies, promotes the proliferation of beneficial intestinal flora, and produces a large number of beneficial metabolites such as butyric acid, lactic acid, antibacterial peptides, B vitamins, VE, digestive enzymes, etc., especially for the "secondary digestion" of the posterior part of the intestine (improving palatability, improving feed intake, reducing the ratio of feed to meat, feeding ratio, feeding to egg ratio, etc.).
2. Powerful butyric acid effect
Clostridium butyrate can produce a large amount of butyric acid, which is an important substance for the development, maturation, regeneration and repair of intestinal epithelial cells, stimulate intestinal epithelial papilla growth and increase tissue weight, maintain the integrity of intestinal mucosal lymphatic follicles, enhance the secretion of mucosal immunity IgA; butyric acid can reverse intestinal permeability, promote intestinal reabsorption of water and sodium, promote gastrointestinal cell proliferation and protein synthesis, and improve livestock and poultry immunity and disease resistance.
3. Strong colonization ability of the middle and posterior section of the intestine
Clostridium butyrate is an anaerobic bacterium, a homologous strain in the intestine, with strong colonization ability. At the same time, it can effectively inhibit the reproduction of harmful bacteria staphylococcus, Clostridium weiss, Escherichia coli, dysentery and Salmonella and putrefaction bacteria, reduce the production of harmful substances such as amines and hydrogen sulfide, and avoid the occurrence of various intestinal diseases (necrotizing enteritis, colitis, ileitis) and related respiratory diseases.
4. Strong secretion ability of digestive enzymes
Clostridium butyrate can produce amylase, protease and lipase, which can promote the digestion and absorption of fat, starch and protein by animals; Clostridium butyrate has the role of amino acid carrier, it can transport all amino acids, but does not decompose amino acids, so it is conducive to promoting animal growth.
5. Clostridium butyrate high stability
Clostridium butyrate can have a high metaspore rate through the optimization of the fermentation process, has good stability, can withstand heat, acid, bile salts, long shelf life, can meet the feed plant granulation processing process, through the digestive tract without inactivation. At the same time, it has strong resistance to some antibiotics and can be used in conjunction with them.
