“Estrous Control and Synchrony in Cattle
Exogenous hormones can mimic the hormones of the natural estrous cycle in cattle. By administering exogenous hormones, producers can control and synchronize estrus in breeding heifers and cows as well as shorten their estrous cycles. Producers can group animals according to the phase of their estrous cycle, which reduces management burdens. Some estrous synchrony regimens may also induce or advance estrus in animals that aren’t cycling (they’re anestrous). For example, a cow is normally anestrous after giving birth, and an estrous synchrony regimen may be used to advance her first heat after calving. This allows her to be bred again sooner. These drug regimens may also be used to advance the timing of the first heat in heifers at puberty.”
