Improving EPD Accuracy

摘要

The promise of using DNA information to improve the accuracy of expected progeny differences (EPDs) on young animals is starting to be realized, at least for Angus cattle. First, there was an agreement between Angus Genetics Inc.~R (AGI) and IGENITY~Rto calculate genomic-enhanced expected progeny differences (GEPDs) for multiple carcass traits using American Angus Association~R carcass and ultrasound data. Then, in November 2010, AGI announced an agreement to similarly accept Pfizer Animal Genetics' High-Density 50K test results for incorporation into GEPDs.
