Mechanism of use of feed additive probiotics

Feed additive Probiotic is a live microbial feed additive that exerts a beneficial effect on animals by improving the balance of intestinal flora. Its main modes of action include: it is conducive to the establishment of normal microflora in the digestive tract of animals, improves immunity and digestion and absorption functions, prevents the synthesis of toxic amines, promotes the growth of beneficial bacteria, and inhibits the growth and reproduction of harmful bacteria.

1. Improve intestinal microecological environment
Under normal circumstances, the vast majority of intestinal cells are innate cells, and a very small amount is other sprouts. There are both positive and negative relationships among various bacterial groups. Positive phase effects promote the development of populations, developing within specific habitats and towards communities, while external phase effects limit or prevent population over-expansion. When these two interactions reach a balance, we call it "micro-ecological balance". However, when certain conditions change, such as physical, chemical or biological changes in the external environment, the body is in a pathological state, immunity is weakened, and antibiotics are used, the proportion of colonies in the intestinal tract will be unbalanced. At this time, spoilage bacteria and pathogenic bacteria It will multiply in large numbers, reduce the beneficial bacteria, cause microbial imbalance, and cause diseases in the animal body. When probiotics enter the digestive tract, on the one hand, they consume a large amount of oxygen in the intestinal tract through growth and reproduction, and capture the growth conditions of other oxygen-type bacteria; on the other hand, probiotics produce some substances by themselves to inhibit the growth of other harmful bacteria. For example, lactic acid bacteria decompose sugars to produce lactic acid and acetic acid, yeast to produce ethanol, etc., all inhibit the growth of other sprouts, so that beneficial bacteria in the intestinal tract regain their dominant position and establish a good microbiome.

2. Enhance animal immune function
Intestinal beneficial bacteria, especially lactic acid bacteria, can promote the immune system of animals, and play an important role in specific cellular and humoral immunity as well as non-specific immunity. For example, Lactobacillus piglet can act as a certain immunoregulatory factor to stimulate the local immune response in the intestinal tract, so that the antibody level and macrophage activity of the body are greatly improved. That is, probiotics can act as antigens to produce corresponding antibodies. In turn, the enhancement of immune function plays an important role in maintaining and promoting the number of intestinal flora. Because the intestinal mucosa is the place where secreted immunoglobulins are produced.
