Avaliação de Endoparasitoses gastrointestinais em ovinos em fazenda experimental na cidade de Porto Velho – RO, Brasil

Gastrointestinal parasitism is of paramount importance in the animal husbandry of small ruminants. Among these, nematodes of the Strongyloides genus stand out, which provides one of the most important gastrointestinal pathological changes in production ruminants. This research aims to analyze the occurrence of endoparasites in sheep that are regularly dewormed. The present work evaluated 30 animals from an Experimental farm using the modified Willis and Mollay technique. According to the results of the feces exams, it could be observed that despite having been dewormed, most of the animals were contaminated with Strongyloides spp., Haemonchus spp. and Trichostrongylus spp. Therefore, it can be concluded that the anthelmintic used did not have a fully effective activity on helminths.
