Synchronisation of oestrus was achieved in a group of three cows and two heifers with dinoprost. Sixty-six hours after the second injection of dinoprost, 0.125 mg synthetic gonadotrophin releasing hormone (GnRH) was given intramuscularly. Concentrations of luteinising hormone (LH) were monitored in peripheral blood and close grouping of preovulatory LH peaks was seen around 2.5 hours after injection of GnRH.
使用氯前列醇使一组三头母牛和两头小母牛实现了发情同步。在第二次注射氯前列醇66小时后，肌肉注射0.125毫克合成促性腺激素释放激素（GnRH）。监测外周血中促黄体生成素（LH）的浓度，在注射GnRH后约2.5小时左右观察到排卵前LH峰值紧密聚集。
