The aim of this study was to evaluate the efficacy of the Lippia sidoides essential oil (LsEO) on sheep gastrointestinal nematodes. Initially, 44 naturally infected sheep were divided and treated with 200 mg kg 1 ivermectin and 230 and 283 mg kg 1 LsEO, respectively, plus the control. Fecal samples were collected from each animal to determine epg at 7, 14 and 21 days after treatment. In another test, 21 sheep were distributed and treated with 200 mg kg 1 ivermectin, 283 mg kg 1 LsEO and the control, respectively. Seven days after treatment, they were euthanized and necropsied to count and identify the nematodes from the abomasum, small and large intestines. In the first test, the efficacy of 230 and 283 mg kg1 LsEO and ivermectin was 38%, 45.9% and 40.2%, respectively, 7 days after treatment, and 30%, 54% and 39.6%, respectively, 14 days after treatment. In the second experiment, the respective efficacy of 283 mg kg1 LsEO and ivermectin was 56.9% and 34.4% against Haemonchus spp., and 39.3% and 63.6% against Trichostrongylus spp.  aAnimal diseases  aAnthelmintics  aEssential oils  aIvermectin  aNematode infections  aParasitology  aPharmacology  aPlant extracts  aSheep  aTrichostrongylus  aAnti-helmíntico  aExtrato vegetal  aHaemonchus contortus  aLippia sidoides  aNematóide  aÓleo essencial  aOvino  aPlanta medicinal  aAlecrim-pimenta  aDrug plants  aIn vivo  aInseticida natural  aNematódeo gastrintestinal  aParasite Egg Count  aPlant oils  aTherapeutic use1 aBEVILAQUA, C.
