Although pedometers are increasingly being used and in-line milk progesterone tests are being developed, the most reliable method for determining the optimum timing of artificial insemination (AI) is the observation of cows standing to be mounted (STBM).
  −
* Ovulation occurs approximately 30 hours after the first display of STBM, which in turn is 24 hours after the LH surge.
  −
* The optimum time to inseminate in order to achieve the best conception rates is six to 24 hours after the first observed STBM.
