The prevalence of natural gastrointestinal nematodes was observed in cattle during the period from June, 2011 to May, 2012 in Rajshahi district. The prevalence of gastrointestinal nematodes was 54.75% (rainy seasons-79.81%, autumn-57.70% summer-44.32% and winter seasons-34.74%). The prevalence of Ascaris sp.,Strongyles (Haemonchus sp., Trichostrongylus sp., Oesophagostomum sp. and Mecistocirrus sp.), Bunostomum sp., Trichuris sp.
