Antimicrobial
What happens biologically
Some volatile phenols, organosulphur compounds and polyphenol-rich extracts interact with microbial membranes or other cellular targets in laboratory systems. In the gut, any effect is shaped by concentration, digestion, feed matrix and the wider microbiota. The practical objective is usually to support microbial balance and barrier function—not to claim that a feed additive treats a diagnosed infection.
