The Estrus Synchronization Planner V11 for cattle producers includes the latest recommendations for application of estrus synchronization protocols and is now available as a free download from the Iowa Beef Center at

The planner is a spreadsheet that assists herd managers in selecting a protocol, planning for implementation and creating a calendar to ensure the appropriate activity occurs on the correct day, said Kansas State University livestock specialist, Sandy Johnson.

The extension group – the Beef Reproductive Task Force – updated the Web tool to help beef cattle producers make decisions for the breeding season. Johnson, who is based in Colby, Kansas, represents K-State Research and Extension on the task force, which is comprised of specialists from K-State, the University of Missouri, University of Nebraska, South Dakota State University, University of Florida, and University of Idaho.

The Estrus Synchronization Planner V11 helps:

  • assist with planning and implementing some of the more complicated synchronization systems;
  • eliminate errors in the timing of injections, starting and ending the feeding of MGA, CIDR insertions, etc;
  • optimize labor use; and
  • provide analysis and comparison of input costs of several synchronization systems.

It includes recommended systems for cows and heifers and helps select systems by type (heat detection and artificial insemination (AI) systems; heat detection and cleanup timed AI systems; and fixed-time AI systems). The planner also provides a list of daily activities, a barn calendar and estimates cost per AI pregnancy.

A list of recommended synchronization protocols for beef cows and heifers, updated for 2011, is also available online at This year’s recommendations include a new protocol designed to reduce synchronization treatment costs.

Future Beef Reproduction Task Force meetings, which are open to veterinarians, artificial insemination technicians, producers and others with interest in artificial insemination in beef cattle, will be held Aug. 31-Sept. 1, 2011 in Joplin, Mo. and Sept. 30-Oct. 1, 2011 in Boise, Idaho.
