Understanding Estrous Synchronization of Cattle

Spanish translation provided by: Maristela Rovai, Assistant Professor & SDSU Extension Dairy Specialist

Reproductive failure is a major source of economic loss in the beef industry. The majority of this loss occurs because cows do not become pregnant during a defined breeding season.

You can give cows an additional chance to become pregnant during a defined breeding season by using estrous synchronization. Synchronizing estrus is simply manipulating the bovine estrous cycle to cause the majority of cows to show standing estrus around the same time.
