O objetivo deste trabalho foi avaliar a utilização do método Famacha como estratégia auxiliar no controle do parasita Haemonchus contortus em ovinos e caprinos no Brasil. A principal característica deste método é a identificação de animais resistentes e resilientes no rebanho, sendo possível a seleção de animais que não necessitam receber tratamento antiparasitário. Além do acompanhamento clínico, foram determinados valores de hematócrito e ovos por grama de fezes (OPG). Ao término do experimento, foi determinada uma considerável redução (75,6%) na utilização de medicação antiparasitária nos ovinos, quando comparado com o controle profilático de tratamento do rebanho todo em intervalos de 30 dias dos anos anteriores. O método Famacha, embora também indicado para uso em caprinos, requer pequenas adaptações para sua melhor aplicabilidade. O método Famacha pode ser utilizado no Brasil com o objetivo de racionalizar o uso dos compostos antiparasitários, preservando sua eficácia por períodos prolongados.The objective of this research was to evaluate the Famacha method as an auxiliary strategy for the control of the parasite Haemonchus contortus in sheep and goats in Brazil. The main characteristic of this method is the identification of resistant and resilient animals within the flock, selecting animals that do not require drug treatment. Haematocrit levels and fecal eggs per gram (EPG) were measure as well as the clinical examination. At the end of the experiment a considerable decrease (75.6%) in antiparasitic drug usage was determined in sheep, when compared to the prophylactic control management, treating all flock in 30 days intervals in previous years. Although the Famacha guide is indicated to be used in goats, some particularities have to be observed to obtain better results. The Famacha method may be applicable in Brazil with the aim of reducing drug usage and prolonging its lifespan.
