Synchronizing Estrus In Beef Cattle  
Synchronization of estrus (heat) involves manipulating the estrous cycle of beef females so they can be bred at approximately the same time. There are several protocols available for synchronizing estrus among beef females. Traditional protocols are designed to mimic or control the corpus luteum on the ovary. New protocols have been designed to control ovulation and/or the follicular waves that occur on the ovary during the 21-day estrous cycle.
