As nematodeoses em equinos podem causar cólicas e diarreias. O objetivo deste estudo foi identificar e quantificar os helmintos predominantes em equinos mantidos em criatórios na região metropolitana de Porto Alegre/RS. Amostras fecais de 68 equinos foram processadas pelos Métodos de Gordon; Whitlock modificado e Roberts; Sullivan. Na presente pesquisa observou-se que 94% (64/68) das amostras fecais de equinos apresentavam ovos de helmintos intestinais, sendo que 78% (53/64) eram de Strongyloidea, 7,81% de Parascaris (5/64) e 9,4% de Oxyuris (6/64). Houve infecção mista com Strongyloidea e Oxyuris equi (9,4%) e Strongyloidea e Parascaris (3,2%). A ocorrência de parasitoses foi elevada, sendo recomendado a utilização de programa de controle parasitário.
