Summary : In order to evaluate the anthelmintic properties of the essential oil of Zanthoxylum zanthoxyloïdes commonly named Fagara on the nematode gastrointestinal parasites, Djallonke breed lambs have been orally treated with 1 mL/ kg and 2 mL/kg of the essential oil diluted to 0.42% for 3 days during natural infestation or controlled infestation with larvae L3 of Haemonchus contortus and Trichostrongylus colubriformis at the rate of 3000 larvae by animal. Compared to the not treated witnesses, the Fagara essential oil has significantly (p < 0.05) reduced the faecal excretion of strongle eggs, the viability and prolificacy of the adult worms and has assured the maintenance of the body weight and the haematocrit throughout the 5 week long trial, independently of the doses tested. In addition, this treatment has markedly alleviated the larvae L3 implantation with a dose-effect relation only on the T. colubriformis larvae. These results clearly show that the Fagara essential oil exhibit some powerful antihelminthic effects and after identification of the all active substances, the use of this essential oil would contribute to limit the use of chemical anthelmintic compounds.
