Abstract
Twenty-six Polled Hereford and Simmental-cross heifers that had not cycled by the beginning of the breeding season were given an ear implant and injected with an estrogen-progestogen compound. The implant was removed after 9 days and all heifers were in estrus 1 to 5 days later. Six heifers conceived the first insemination, 11 the second, and 24 during the 65-day breeding season.
