The Fall 2012 American Simmental Association Genetic Evaluation marks the
first time major breeds have eXpressed their EPDs on a common base – 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 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 accus-
tomed 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.
