The 587 Holstein cows which calved from Jan 1983 to Dec 1984 at an integrated dairy farm in Chungnam province were examined for the incidence of reproductive disorders and their conception rate after treatment. The incidence of reproductive disorders was 47.9% (281 heads) among 587 heads which calved. As number of calvings increased, the incidence of reproductive disorders decreased. The cows which calved in spring and summer showed significantly higher incidence of reproductive disorders than those which calved in autumn and winter (p 0.05)
