Overall objective

  • To optimize protocols to encapsulate essential oils and test their antimicrobial activity in target regions of the chicken gut.


  • The levels of specific essential oils required for optimal antimicrobial activity in the gut have been established.
  • The encapsulation protocol delivers active essential oil to the lower gut, but the protocol needs to be improved in order for the oil to withstand pelleting conditions during feed processing.


  • Essential oils delivered to appropriate regions of the gut under field conditions may serve as a practical alternative to antimicrobials currently used in the poultry industry.
