The popular estrus synchronization planner for beef cattle is now available in an online, phone application format. First available years ago through the Beef Reproduction Task Force as a for-purchase tool, the planner and its multigroup version have been offered at no charge via the Iowa Beef Center website since 2011. In 2025 alone, the regular estrus synchronization tool has been downloaded more than 1,860 times to date.
IBC research scientist Garland Dalhke is a member of the task force and developed and maintains the spreadsheets. Now he’s created an online version also available at no charge.
“This version can be used on computer or phone or other device directly from the site. Inputs are the same as the previous versions and both a screen and calendar printout are possible,” he said.
See the new planner and try out the various options to see what works for your farm. The Beef Reproduction Task Force was formed in 2000 as a multi-disciplinary group of research and extension faculty members from universities across the U.S. with a focus on beef cattle reproduction, management and reproductive technologies.
