The mechanism of regulating the flora structure in the host through competition mainly includes the following aspects:
Metabolic antibacterial chemicals inhibit the improvement of bacteria, and lactic acid bacteria drinks reduce the pH value of the natural environment of gastrointestinal tract according to endotoxin, hydrogen peroxide and other chemicals and organic substances (including lactic acid bacteria, formic acid, caproic acid, butyric acid, etc.). ), inhibit the growth and development of harmful microorganisms, and the hydrogen peroxide caused by it inhibits the development and reproduction of bacteria, so that beneficial organisms have the upper hand in the competition of strains; Competing with bacteria for nutrients or adhesion domains, inhibiting the growth and development of other organisms. Microecological agents with antagonistic properties are applied to cultured animals or added to feed to kill or inhibit microorganisms and provide excellent living conditions for cultured animals.
Avoid the accumulation of toxic substances such as amine and ammonia, and protect the body from harm. Under the direct influence of some stress response factors, the small and medium-sized biodiversity in the intestines and stomach of animals is unbalanced, which leads to the imbalance of beneficial bacteria in the body, the promotion of aerobic bacteria, and the decomposition of protein to produce harmful substances such as amines and ammonia. Animals mainly show pathological state. There are also some probiotic powders, such as some lactic acid bacteria, streptococcus infection, Bacillus subtilis and so on. It can prevent the toxic and side effects of amine and ammonia. Superoxide dismutase (SOD) caused by most aerobic bacteria can help animals to scavenge free radicals. Some probiotics, such as Bacillus subtilis, can produce hydroxyl antimycin and sulfate-soluble antioxidant in gastrointestinal tract, thus reducing the concentration of harmful substances such as ammonia and indole in blood and excrement.
Stimulate human immune system and enhance immunity. Microecological agents in feed additives are effective immune partners, which can stimulate animals to cause interferon suppository, improve the concentration of human immunoglobulin and the activity of macrophages, and stimulate the immune function of the body according to non-specific hormone regulatory factors. After animals take probiotic powder orally, the intestinal bacteria are regulated, so that the intestinal microecosystem software is in the best balance state, and the intestinal mucosa-related lymphoid tissues are activated, thereby improving the metabolism of SLGA antigen, improving the immune recognition ability, inducing T, B lymphocytes and macrophages to produce cytokines, and activating the whole immune system according to the recycling of reticulocytes, thereby improving the human immune system of the body.
It can promote the growth of animals and improve the body's resistance to some extent. As a microecological preparation of feed additives, its bacteria contain a lot of nutrients, which can supplement vitamins for animals. The crude protein content of photosynthetic bacteria reaches 65%, and it is also rich in B vitamins, acid regurgitation, biotin, folic acid tablets, carotene, calcium, phosphorus, various nutrients and coenzyme Q, etc.
