The Estrus Synchronization Planner has been available since 1998, developed by the Iowa Beef Center. It has evolved over the years, proving to be an effective and easy tool to help select and implement synchronization protocols. The program is available as a free excel spreadsheet download or as a mobile version. Both include the protocols recommended by the Beef Reproduction Task Force.

The excel spreadsheet can downloaded from the Iowa Beef Center or visit the Applied Reproductive Strategies in Beef Cattle website. To download this version, the computer must have excel for the program to function.

The mobile version can be downloaded on the EstruSync website. It will contain the critical features to function but will not be identical to the full excel spreadsheet version. A wireless or internet connection is required and may limit the use in pastures depending on cellular coverage.

Features include creating a synchronization and breeding calendar with exact dates and times when hormones should be given and/or removed, when heat detection should occur and breeding. Timing is critical for a successful program. It allows for a cost comparison between protocol systems and a cost response analysis.

The following are snapshots of the excel spreadsheet version of the Estrus Synchronization Planner to highlight what it offers. For a detailed description of the program visit the Applied Reproductive Strategies for Beef Cattle website to review an article by Sandy Johnson from Kansas State University.
