The American Angus Association. Board of Directors approved changes to the $Value Indexes during the February board
meeting Feb. 18-21, 2019. Updated $Value Indexes will be available this June, and changes include revisions to Beef
Value ($B), adding Maternal Weaned Calf Value ($M) and
rounding all $Values to whole dollars to eliminate decimals. Quality Grade ($QG) and Yield Grade ($YG)
will be removed because $QG is redundant to the Marbling EPD, and $YG is redundant to Fat and REA EPDs. In
addition, a balanced index will be implemented June 2020 with a complete education plan to be executed with the membership
and industry to take place over the next 15 months.
The use of multi-trait selection indexes as tools for commercial cow-calf operators and seedstock breeders is rapidly
evolving in the beef industry. Selection indexes are a tool to select for several traits at once. An index approach
takes into account genetic and economic values to select for economic merit. A multi-trait index approach can be contrasted
to single-trait selection or independent culling levels. An index is challenging to develop, but the end result is easy
to use, adding simplicity and convenience of a multi-trait approach. The Expected Progeny Differences (EPDs) currently
available through the American Angus Association, along with numerous individual performance measures, can become overwhelming.
Weaned Calf Value ($W), Feedlot Value ($F), Grid Value ($G) and Beef Value ($B) are bioeconomic
values, expressed in dollars per head, to assist commercial beef producers by adding simplicity to genetic selection decisions.
