1. Promote digestion and absorption of nutrients
Probiotics can synthesize digestive enzymes. Together with the digestive enzymes synthesized by animals, they participate in the digestion of nutrients in the intestine, stimulate the secretion of digestive enzymes in animals, reduce the depth of small intestinal crypts, increase the height of villi, increase the surface area of small intestine, and promote Intestinal absorption of nutrients.
2. Improve the body's immunity
The self-structure of probiotics such as peptidoglycan, lipoteichoic acid and other components can be used as antigens to directly play an immune activation role, or stimulate the host immune system through autocrine immune activators, thereby improving the immunity of animals and enhancing the body's innate immune cells and natural killer cells, activate dendritic cells, stimulate the body to produce cytokines, and stimulate B cells to secrete antibodies. Probiotics can stimulate the intestinal tract to produce secretory globulin A (SIgA) to protect the body's health.
3. Maintain the balance of intestinal flora structure
The gut is not only a normal part of the body, but also participates in important physiological activities of the body. At the same time, there are also complex intestinal flora in the gut, which play important functions on the growth, development and health of the host.
4. Improve meat quality
Probiotics can increase muscle brightness by inhibiting lipid peroxidation and delaying the formation of methemoglobin. Probiotics can also affect fatty acid metabolism and improve muscle tenderness.
5. Improve the body's antioxidant level
Oxidants in the body, such as oxygen free radicals and hydroxyl radicals, contain unpaired electrons and are prone to redox reactions. When there are too many oxides in the body, it will cause oxidative damage to the body. There is an antioxidant system in the body, which constantly removes the oxides synthesized by the body and maintains the dynamic balance of the oxides.
6. Suppresses Intestinal Inflammation
Probiotics can reduce the body's inflammatory response.
Protect intestinal mucosal barrier
Probiotics can reduce intestinal mucosal permeability, thereby protecting the integrity of the intestinal mucosal barrier [8] .
7. Breeding water quality regulation
Probiotics participate in various circulatory processes in the water body. Through their own metabolism, they consume organic matter in the water and reduce the concentration of nitrite nitrogen and ammonia nitrogen in the water body, thereby achieving the effect of improving and maintaining good water quality
