The control of estrus, and more importantly ovulation, may be desirable in a breeding program to service an animal at a predetermined time, to synchronize ovulation in a group of mares, or to spread ovulations over a prolonged period of time according to the various needs of managing the breeding animals. Ideally, the goal would be to control ovulation with enough precision that breeding could be done without the necessity of estrus detection.
