Genomic Enhanced EPDs Powered by GeneSeek GGP-HD
The bulls in this year’s sale have been tested using GeneSeek’s GGP-HD genomic test offered through the
American Angus Association. This means that in addition to the pedigree, performance and progeny information
that are used in the calculation and reporting of Angus EPDs, genomic test results have also been incorporated
into the EPD, and thus these individuals have added predictability or accuracy.
Genomic results are a way to enhance predictability of current selection tools, to achieve more accuracy on
EPDs for younger animals, and to characterize genetics for traits where it’s difficult to measure the animal’s own
performance for the trait (i.e. carcass traits in breeding stock or maternal traits in bulls).
GE-EPDs are important because they make use of the results from the DNA test in addition to all other sources
of information to provide added accuracy and reliability to the animal’s EPD. In fact, depending on the trait, GE-
EPDs on unproven bulls have the same amount of accuracy as if they had already sired 8-20 calves.
Genomic Enhanced EPDs offer our customers an excellent risk management
tool. If you think about the amount of time and how old a sire will be before
you collect enough data to achieve the level of accuracy gained by the genomic
information, you directly benefit from this added confidence.
