Conteúdo: 	This study was conducted in Patos county, a semi-arid area with caatinga vegetation in Paraíba State, northeastern Brazil. Twenty-four male goats of rnixed breeds were used. The animaIs were separated in age groups from 1-12 months, i. e., 1-2,3-4,5-6,7-8,9-10,11-12 months, with four animals in each group. The animals were slaughtered and necropsied to recover and identify adult worms. The goats were exposed to nematode infection from the first month of life. The most prevalent nematodes in decreasing order were: Trichostrongylus colubrifonnis, Haemonchus contortus and Oesophagostomum columbianum. Age of the goats did flot appear to be a factor in resistance to gastrointestinal nematode infection. Worm burdens of 11-12 month old animaIs were significantly (P<0.05) higher than in other age groups.
