From May 1976 to June 1978, an epidemiological study on gastro-intestinal nematodes of the Zebu calves on native pasture, was carried out in the Pantanal region, Brazil. Haemonchus, Oesophagostomum and Cooperia were the most common genus with high prevalence. Ninety-five percent of total number of Haemonchus collected were identified as Haemonchus similis. Faecal egg counts varied greatly from season to season during the experiment period. On the whole, the counts reflected the fluctuations of worm burden. The counts, however, did not always reveal the degree of infection with gastro-intestinal parasites. It was proved that Haemonchus spp. was the most predominant in the larval identification, but Cooperia spp. was more abundant than Haemon...
