Translating and Applying Genomic EPDs

Expected progeny differences (EPDs) are a widely utilized tool in making genetic decisions centered around breeding objectives. With the progression of DNA technology, the industry has been able to incorporate genomics into the numbers that are used to calculate EPDs. Prior to inclusion of genomic information, we relied on pedigree-based relationships that operate on the averages. This assumes a 50% contribution from the dam and 50% contribution from the sire to the breeding value of the offspring. However, an animal’s actual genetic merit or it’s EPD value for a given trait can be…
