Parasites cause great economic loss in livestock in Korea, and can be categorized as either or indirect losses. In order to monitor the parasites from October 2005 to January 2006, 401 samples were randomly collected from cattle farms and examined the prevalence of gastro-intestinal (GI) parasites by using the sucrose flotation method and formalin-ether centrifugation method. The overall infection rate of GI parasites was about 43.4%. Of these parasites, nematodes were identified as Capillaria bovis (5.5%), Strongyloides papillosus (2.5%), Trichuris discolor (1.2%). Cestoda was observed only one species, Moniezia benedeni (2.2%). The rate of Eimeria spp was 39.2%. A total of five species of Eimeria was identified; among the species identified as above E bovis and E zuernii appeared with relatively higher infection rates. The combined infection of parasites was 35.2% in single species, 29.0% in double and 2.0% in triple infections. No cases of clinical symptoms were observed in this survey. The EPG levels of each species of parasites were very low in all infected cases.
