Kelli Retallick, director of genetic and genomic programs, explains the differences in old and new genetics, how they contribute to the genetic evaluation, and how Angus Herd Improvement Records (AHIR) are reflected in EPD calculations. To answer these questions, Retallick uses a case study to show how the American Angus Association accurately calculates EPDS.
