Mechanism of action of fermentation products

The mechanism of action of microbial fermented feed:

1. Competitive inhibition: including competition for nutrition and colonization sites (to prevent the attachment and reproduction of harmful microorganisms in the intestinal mucosa).

2. Improve the pH of the intestine and inhibit the growth of other pathogenic organisms.

3, antibacterial effect, the formation of an acidic environment in the intestine, play a bactericidal effect; produce lysozyme to inhibit the growth of pathogenic bacteria.

4. Supplement nutrients. The beneficial bacteria in the direct-feed bio-fermented feed can be metabolized in the intestine to produce a variety of digestive enzymes, amino acids and vitamins.

5. Improve the body's immune function. The beneficial bacteria in microbial fermented feed are good immune activators, which can stimulate the growth of intestinal immune organs and stimulate humoral and cellular immunity in the body.

Competitive inhibition:

Includes competition for nutrition and colonization sites that prevent the attachment and reproduction of harmful microorganisms in the intestinal mucosa. A variety of microbial communities grow in the intestines of healthy livestock, and various microbial communities are interdependent and mutually constrained to form a micro-ecological balance in the intestines of livestock and poultry, establishing a normal and well-balanced gut microflora. It is very important to resist pathogenic microbial infections.

Due to the interaction between microorganisms, existing microorganisms in an ecosystem can prevent new organisms from invading this part. For example, Lactobacillus acidophilus has a strong affinity for pig intestinal epithelium, thus reducing Escherichia coli. The opportunity to combine with the intestinal epithelium. Therefore, take it for young animals with slow or dysfunctional flora.

Chickens raised by modern hatching methods have not been exposed to adult chickens. They cannot establish intestinal flora as quickly as farm-family chickens, and inoculate chickens with appropriate intestinal micro-organisms to help them establish their own intestinal bacteria. Groups can increase their resistance to Salmonella. For adult animals, since many microorganisms can only survive in the intestine for quite some time, it is necessary to feed a large amount of probiotics to keep a certain microorganism in the intestine. Colonization.

In some cases, such as stress, disease, and long-term use of broad-spectrum antibacterial drugs, can cause damage to the micro-ecological balance in the intestine. While feeding microbial feed, beneficial microorganisms reach the digestive tract and rapidly multiply in the digestive tract, which is dominant in quantity. Together with their growth and metabolism, the anaerobic environment greatly inhibits the aerobic pathogenic bacteria. Growing and breeding. Microbial preparations are of great importance.

Improve the intestinal environment:

By producing organic acids such as lactic acid and acetic acid, the pH value in the digestive tract is lowered, and the growth of other pathogenic organisms is inhibited, thereby maintaining or restoring the balance of the microbial communities in the intestinal tract, thereby achieving the purpose of preventing disease and promoting growth.

Bacteriostatic effect:

Many lactic acid bacteria and streptococci can produce bacteriocins, such as nisin, which inhibit the growth of Salmonella, Shigella, Pseudomonas aeruginosa and Escherichia coli.

Under certain conditions, some lactic acid bacteria can produce a small amount of hydrogen peroxide, which can inhibit the growth of many bacteria, especially Gram-negative pathogens.

As a result of the activation of the lactic acid catalase-methionine reaction system in the large intestine, the reaction product can inhibit the growth of bacteria, and can also form an acidic environment, thereby playing a bactericidal role. In addition, some beneficial microorganisms can produce lysozyme, thereby inhibiting the growth of pathogenic bacteria.

Supplement nutrients and prevent harmful substances:

The beneficial bacteria in direct-feed microbial preparations can be metabolized in the intestine to produce a variety of digestive enzymes, amino acids, vitamins (K, C, B1, B2, pantothenic acid, niacin, biotin, inositol and folic acid, etc.) and other metabolites. As nutrients are absorbed and utilized by the livestock and poultry body, thereby promoting the growth and weight gain of livestock and poultry.

Since direct-feeding microorganisms can promote the digestion and absorption of nutrients, the production of ammonia and other spoilage substances can be reduced. Studies have shown that feeding fermented feed can reduce the content of ammonia in contents, feces, portal veins, and the content of spoilage substances such as p-cresol, hydrazine, and 3-methylhydrazine in the contents of the intestines, alleviate the smell of feces, and purify the animals. Avian environment. In addition, direct feeding bio-fermented feed beneficial bacteria can grow in the intestine to form dense membrane flora, forming a biological screen to prevent the absorption of harmful substances and waste.

Improve immune function:

The beneficial bacteria in the microbial fermented feed have good immune activation functions, which can stimulate the growth of the intestinal immune organs and stimulate the body's humoral and cellular immunity. Direct feeding of microbial fermented feed can increase the level of animal and poultry antibodies or increase the activity of macrophages, enhance immune function, and timely kill pathogenic bacteria invading the body, thus preventing the occurrence of diseases.
