This survey was carried out to investigate the seroprevalence of antibodies to Neospora (N.) caninum in dairy cattle raised in Kangwon province in Korea. A total of 349 sera collected from dairy cattle were tested for N. caninum antibodies using an indirect immunofluorescent antibody test (IFAT). Ninety six (27.5%) dairy cattle were positive by IFAT. Seroprevalence of cows was 28.9% (91/315) and seroprevalence of boars was 14.7% (5/34). The seroprevalences of cows were increased according to the ages from 19.6% in cows less than 2 year-old to 50.0% in cows more than 7 year-old. Among the seroprevalences of cattle according to the raised areas, five counties or cities, Wheongsung was 34.6% (27/78), Wonju was 29.3% (46/157), Hongcheon was 28.9% (13/45), Chuncheon was 15.0% (3/20) and Cheolwon was 13.3% (2/15). It was proved that dairy cattle raised in Kangwon provinces exposed extensively and seriously to N. caninum.
