What Are EPDs?
Expected Progeny Differences (EPDs) are a very important tool used in genetic selection at BSG. They are the ingredients to economic selection indexes, like $Durham or the suite of indexes published by breed associations on an animal’s genetic profile. EPDs are used to compare the differences in predicted performance of an animal’s offspring for specific traits important to cattle production. The calculation of EPDs is complex and driven by pedigree estimates, the individual’s performance data from within their contemporary group, and progeny performance data. The American Shorthorn association offers thirteen different EPDs for given traits measured.
