Fermented feed is a "live" feed, of course, first of all because of the existence of these living microorganisms. But the "live" of the fermented feed is not just to say that these beneficial microorganisms are "live", or that these beneficial microorganisms are not simply alive.

Their "living" provides unlimited possibilities. At present, we know that these "actives" of beneficial microorganisms can exclude the existence of harmful microorganisms; they can produce beneficial substances, and many of them are biological "living" substances. , Such as lactic acid bacteria produce lactic acid and volatile short-chain fatty acids, such as ethanol produced by yeasts, and the flavor substances they produce together, such as various enzymes produced by Bacillus, and antibacterial peptides produced by Bacillus and lactic acid bacteria or Antibacterial substances such as bacteriostat.

In addition, their "liveness" also plays a role in entering the intestine, providing more possibilities, such as adhesion to the intestine to compete for the colonization of harmful bacteria through space; for example, a complex immune "dialogue" with the host to regulate The intestinal immune response reduces the intestinal inflammation; for example, by affecting the "hepatic intestinal axis" or even the "brain and intestinal axis", it affects the health of the host's whole body; and there are still many unknown contents to be explored here, which are also fermented feed The application in the future provides more imagination space.
