Genetically Enhanced EPDs Basics
Genetically Enhanced EPD
Utilizing Expected Progeny Differences (EPDs) is the most expedient way to make genetic improvement in beef cattle. EPDs are the expected difference in performance of a bull’s progeny compared to the performance of another sire’s progeny. EPDs should not be used as a stand-alone metric, rather, they are most useful in comparison between individuals. EPD accuracy increases when data is collected on an individual’s progeny. The amount of data accounts for the difference in accuracies between young bulls and older AI sires. However, the use of DNA testing and the resulting GE-EPDs increases the predictability of the progeny. Depending on the trait, the GE-EPDs on unproven bulls have the same amount of accuracy as if those bulls had already sired between 8 to 33 calves. Genetically Enhanced EPDs (GE-EPDs) are calculated from these sources: 1) The individual’s pedigree 2) The individual’s performance record
3) The genomic test results of the individual 4) When available, the performance and genomic results of progeny All of our bulls and females have been DNA tested with Angus genomic profiles. Therefore, all bulls and females in the sale have Genetically Enhanced EPDs.

We are enrolled in Maternal Plus Maternal Plus provides Angus breeders and their customers the information they need to make effective selection decisions. It’s a voluntary, inventory-based reporting system designed to capture additional reproductive trait data and, ultimately, expand reproductive and lifetime productivity tools. Visit AAA Login or contact the Association for more information.
We encourage you to use registered Angus bulls with data that has been processed by the American Angus Association that allows you to select bulls with greater confidence and accuracy.
