Abstract

Data from this analysis suggest that concurrent selection for both average daily gain and residual feed intake (RFI) may identify beef heifers that have improved fertility and longevity without impacting growth and maternal EPDs. As the beef industry continues to focus on sustainability, and thus efficiency, identification of commercial breeding stock that fit this mold will be imperative.
