The Fall 2012 ASA Genetic Evaluation marks the first time
major breeds have expressed their EPDs on a common base
(i.e., the same scale). The common base was a natural evo-
lution 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 pre-
dictions 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 ac-
customed 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 per-
centile tables to develop a “feel” for the new EPD base.
