Bull Selection Clinic
Friday, May 3, 4:00 pm, Tama Livestock Auction

Understanding and using some simple tools can help cattle producers make the right selection for new herd bulls during upcoming bull sales. That’s why a bull selection clinic is scheduled prior to the Friday, May 3, bull sale held by Iowa Cattlemen’s Association (ICA) at the Tama Livestock Auction, Tama. There’s no cost to attend and no preregistration is necessary.

Dr. Patrick Gunn, the newest addition to the ISU Extension beef team and statewide cow-calf specialist, and I will break down the process of bull selection into simple steps and assist you with interpreting the EPD numbers in the catalog. We can help you evaluate your cow herd and determine the economically relevant traits that you want to emphasize. With that information, you can use the index EPDs and visually appraise the bulls to identify some options that will help you get the most benefit from your cow herd.

The sale will feature bulls that have been through ICA’s Bull Evaluation Program. Bulls that go through this 112-day test are evaluated for growth, carcass traits, yearling weight, disposition and scrotal circumference, and are some of the breed’s best pedigrees for calving ease, performance and carcass merit. The Tama sale will also include a group of replacement heifers for sale starting at 6 pm.

And beyond their convenience, use of indexes can facilitate significant genetic progress on several traits at the same time within a herd or a breed, says University of Guelph animal scientist Steve Miller, PhD.
