The Fall 2012 ASA Genetic Evaluation marks the first
time major breeds have expressed their EPDs on a com-
mon base (i.e., the same scale). The common base was
a natural evolution for the RAAA/ASA genetic evaluation
partnership. Though forming a common base will initially
lead to some confusion, the boards of both organizations
unanimously agreed that it was a positive step for the
beef industry — a step that allows producers to directly
compare genetic predictions from the largest multi-breed
database in the world.
As with any progress, there is change. Breeders and com-
mercial producers will need to adjust to the new base.
Much like converting from Fahrenheit to Celsius, it may
be a struggle at first; however, over time we will all grow
accustomed to the new scale. For example look at the
average EPDs of purebreds shown in this table.
The change to the base does not change the evaluation of
animals; it just changes the magnitude of the EPD. It has
the same impact on all animals. Be sure to use the new
percentile tables to develop a “feel” for the new EPD base.
