摘要：

A longitudinal study on the incidence and occurrence pattern of ovarian cysts was carried out in 150 postpartum dairy cows. The incidence rate for ovarian cysts was 18.9%. New cases occurred between Days 23 and 120 with the highest incidence between Days 61 and 90 postpartum. The mean duration of ovarian cysts was 28 +/- 3 days. Cysts were classified as follicular, luteal, and initially follicular and later luteal in 46.1%, 30.8% and 23.1% of cases, respectively. It was concluded that ovarian cysts are common among dairy cattle in East Africa and the tropics; it is possible that case discovery rates are low. The optimum time for screening and treating cases of ovarian cysts was found to be 60 days postpartum.
