Detecting standing estrus (“heat detection” or “detecting standing heat”) is simply looking for the changes in animal behavior that are associated with a cow/heifer standing to be mounted by a bull or another female. Detecting animals in standing estrus is critical to the success of any artificial insemination program. Animals not in estrus around the time of insemination have little chance of becoming pregnant.
Estrous-detection aids or estrous synchronization protocols can greatly increase the likelihood of detecting cows in standing estrus.
