Volatile oils of thyme are among the main essential oils used in the food industry and in cosmetics as preservatives and antioxidants. Specific applications studied in poultry include:

  • Antibacterial: Thyme oil (1 g/kg of diet) proved to be effective in reducing Coliform counts when it was used to create a spray for the purpose of hygiene improvement.
