Abstract
In five trials during 1983 and 1984, 238 cows and 54 heifers were synchronized with Syncro-Mate-B® and artificially inseminated 48 hours after implant removal. The conception rate was 42.5% in cows that were cycling and 19.8% in cows that were not cycling before Syncro-Mate-B® treatment. Heifers started on the Syncro-Mate-B® treatment before day 11 of the estrous cycle had a higher conception rate (64.3%) than heifers started after day 11 (38.5%). Conception rates among the trials varied from 19.8 to 64.3%.
