Relatório Final de Estágio Obrigatório e Trabalho de Conclusão de Curso

Abstract

This study, conducted in the southern region of Mato Grosso do Sul, investigated the current parasite management strategies adopted by cattle producers and their perceptions on the topic. The objective was to assess producers’ perception of the main parasites and their economic impacts, identify the products used, their frequency and selection criteria, and evaluate access to technical guidance and knowledge about antiparasitic resistance. Data were collected through questionnaires applied in 31 farms across seven municipalities. The results revealed wide variation in treatment strategies, a high frequency of reported product failures, predominant use of ivermectin, and decisions mainly guided by personal experience. Low perception of losses caused by gastrointestinal nematodes, limited knowledge of diagnostic tests for resistance, and unequal access to technical assistance were also observed. It is concluded that parasite management in the region presents weaknesses that favor the development of antiparasitic resistance, highlighting the need for standardized practices, educational actions, and stronger technical support for producers.
