What is the main advantage of using Expected Progeny Differences (EPDs)?

The main advantage of using Expected Progeny Differences (EPDs) lies in their ability to track heritable traits within livestock breeding programs. EPDs are valuable tools that provide estimates of the genetic potential of an animal's offspring for specific traits, such as growth rate, reproductive performance, and feed efficiency. By analyzing these differences, breeders can make informed decisions about which animals to mate based on the traits that are most desirable for their breeding goals.

This tracking of heritable traits through EPDs improves the overall genetics of a herd over time, as it allows producers to select for desirable characteristics while minimizing undesirable ones. Ultimately, the use of EPDs leads to more predictable improvements in traits that can be passed on to the next generation, contributing to better productivity and profitability in livestock operations.
