EXPLANATION OF ASA’S NEW EPD EVALUATIONS
Presenting Fall 2012 EPDs on a NEW BASE:
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 evaluation of the RAAA/ASA (Red Angus Association of America /
American Simmental Association) 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 commercial 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
to the right.
The Changes 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.
