Expected Progeny Difference (EPD)

EPDs allow bulls from the same breed to be directly compared from one seedstock operation to another. Weaning weight (WW) and yearling weight (YW) EPDs can be used to evaluate potential differences for growth. Generally, it is best to focus on either WW or YW and not both.

The heritability estimate for YW from the Angus Association is 0.42 compared to 0.28 for WW. For most producers, YW is probably a better indicator of growth potential than WW. Remember more growth is not always better, especially if replacement heifers will be kept or calves will be sold prior to entering the feedlot.
