The incidence of cystic ovaries in dairy cattle housed in a total confinement system



The incidence of cystic ovaries in dairy cattle housed in a total confinement system



Canadian Journal of Comparative Medicine 49(1): 55-57



The incidence of cystic ovaries following 1830 calvings of 1061 dairy cows maintained in total confinement was evaluated. The overall incidence was 14% of lactations and 22% of cows during a three year period. Fewer primiparous than multiparous cows became cystic, 5.7% vs 18%, respectively. There was an unexplained higher incidence (18%) among calvings in 1979 than in 1980 (12%) and 1981 (13%). There were no effects due to season of calving or genetic line of cow. During the last year of the study milk production by cystic cows was significantly greater than that by non-cystic cows.
