Multi-breed EPD base simplifies selection
Since 2010, the Red Angus Association of America (RAAA) and the American Simmental Association (ASA)
have combined their growth and carcass datasets to provide commercial producers with the most reliable
EPDs in the beef industry. In the summer of 2012, RAAA and ASA adopted a common base for Growth (BW,
WW, YW, Milk) and Carcass (MARB, YG, CW, REA, FAT) EPDs so that all animals registered in either RAAA
or ASA can be directly compared – regardless of breed makeup.
What is BASE?
For decades, each breed association has presented EPDs in their own language (the base). Base is no more than a reference point for any trait
against which subsequent generations of animals are compared. The establishment of a base ensures that the population future generations are
compared to remains stable, which allows the breedʼs genetic trend to be accurately identified.
Raw Genetic Value + Base Adjustment = Published EPD
Study Percentile Ranks…
Percentile ranks are an easy reference and therefore a powerful tool to assist you in becoming accustomed to the new multi-breed base. Red
Angus EPD percentile ranks are presented along with all active animalsʼ EPDs, and reference how animals compare within their respective Red
Angus subpopulations, i.e. Sire Summary Sires, Active Dams, Non-Parent Bulls, etc. Itʼs important to realize that although the multi-breed base al-
lows for the direct comparison of Red Angus and Simmental EPDs, the percent ranks for Red Angus animals will continue to simply compare the
genetics of Red Angus animals against other Red Angus. Thus, an animal that was in the top 10% for growth under the old Red Angus base will still
be in the top 10% for growth in the new Red Angus multi-breed base.
Example:
In the past, you preferred to purchase bulls that had a -2.0 or lower BW EPD.
Since a -2.0 on the old RAAA base represented the top 20% for BW, you now need to use -2.7 as your critical selection threshold as that represents
the top 20% for BW on the new multi-breed base.
