Peppermint (Mentha piperita) has been used in traditional folk medicines since ancient times, as a remedy for several conditions and illnesses. Specific use relating to poultry include:
  • Insect repellent: Peppermint is used against endoparasites in poultry in British Columbia. The oil has larvicidal activity against Aedes aegypti, Anopheles stephensi and Culex quinquegaasiatus mosquitoes.
  • Egg Quality: The addition of dry or fresh peppermint leaves to the diet of laying hens has been proven to significantly increase egg weight, egg production, egg mass, and feed intake.
  • Anticoccidial: Peppermint oil was found to be somewhat effective at reducing the number of Eimeria spp. which cause coccidiosis in chickens.
  • Antiviral: Peppermint oil has also shown to be of benefit against Newcastle disease in chickens.
