Estrous Synchronization for Beef Cattle

This Fact Sheet discusses the potential benefits of estrous synchronization, how the products and programs work, and the results and costs involved. Estrous (heat) synchronization is a management practice that can help beef producers improve production efficiency and economic returns. It can help shorten the breeding and calving seasons and help increase calf weaning weights. Its purpose is to control estrous and ovulation in cycling females, so that breeding can be completed in a short period of time. Instead of females being bred over a 21-day period, synchronization can shorten the breeding period to less than five days, depending on the program selected. The use of synchronization has great potential for improving beef production, but it requires good management for success. Producers should understand the advantages, as well as the requirements for a successful estrous synchronization program. They should also know how the different estrous synchronization products and programs work, and the expected results and costs involved before initiating the practice
