Some of these effects may positively impact the management of methane mitigation and ammonia losses. • Animal health: Research has shown that EOs may have direct antimicrobial effects and indirect effects (quorum sensing interference or QSI), which may result in reducing pathogenicity by disturbing bacterial communication. • Animal welfare: Research has shown that EOs also show promise for deworming and fly management in ruminants.
