title: Treatment of cystic ovaries in dairy cattle using human chorionic gonadotropin or a compound consisting of human chorionic gonadotropin with progesterone.
abstract: The present study deals with a comparison of HCG and HCG + P (N) as to their efficiency in the treatment of the ovarian cystic syndrome in dairy cattle (263 cases). The intervals between treatment and first oestrus were the same in both groups (22 vs. 23 days), whereas the cows of the HCG-group conceived earlier (29 days) than the cows of group N (36 days), the difference was not, however, significant. The conception rate after first AI was almost significantly higher in the HCG-group (67% vs. 49%, P less than 0.05). The number of inseminations required per pregnancy was also almost significantly lower in the HCG-group (1.22 vs. 1.48, P less than 0.05). The conclusions drawn were the following: the treatment of ovarian cysts with HCG was somewhat more effective than a treatment with N, thus confirming the previous results achieved under Finnish conditions.
