Even though expected progeny differences (EPDs) have been around since the mid-1980s, some skepticism still exists about their effectiveness as a selection tool. In this study, Kansas State Univ. researchers analyzed data on 3600 Charolais-sired calves in 31 commercial herds to compare progeny performance with the EPDs of their sires. Traits analyzed were birth weight (BW) and weaning weight (WW). All of the progeny were crossbreds. They were sired by 224 purebred Charolais bulls having average accuracies of 0.79 and 0.75 for BW and WW, respectively. Correlations for sire effect on BW and WW were favorably related to actual progeny performance with correlations of 0.59 and 0.39, respectively. The authors noted that the lower WW response may have been due to differences in postnatal management practices between commercial and seedstock herds. This study further adds to the body of research validating the use of EPDs as an effective selection tool for BW and WW in commercial herds (Clark et al. 2004. Prof. Anim. Sci. 20: 503).
