Consignors to the Iowa Tri-County Steer Carcass Futurity are able to utilize growth, health, and carcass data to make changes in their cowherd. Non-weaned calves were 3.4 times more likely to experience bovine respiratory disease (BRD) than weaned calves, independent of differences in age, test center, or vaccine status. Calves vaccinated with killed vaccines were 2.2 times more likely to experience BRD than calves vaccinated with modified-live virus vaccines, independent of other factors.
Other factors influencing net return and carcass traits are discussed in detail.
