Abstract: Estrus, ovulation, and conception following timed insemination were studied in 500 Romney ewes treated with progestagen and gonadotropins. The ewes were treated with intravaginal sponges containing 40 mg "Crondone" for 14 days. At the time of sponge removal all ewes received an im injection of 500 IU pregnant mare's serum gonadotropin. 24 hours later 1/2 of the ewes received an im injection of human chorionic gonadotropin. The ewes exhibited estrus sooner after sponge removal in April than in January (34.9 vs. 38.9 hours, p less than .001). The interval from sponge removal to ovulation was also shorter in April than in January (=6.3 vs. 62.1 hours, p less than .01). There were no marked differences between treatments or season on the mean interval from estrus to ovulation. The types of gonadotropin treatment had no effect on the estrus-ovulation time relationships, and there were no marked effects of season, hormone treatment, or time of insemination on lambing rate. |
