The American Angus Association’s (AAA) $Value indexes provide commercial cattlemen with a tool to select for several traits at once.  The latest $Value, Weaned Calf Value ($W) expressed in dollars-per-head, includes the impact of both revenue and cost differences in the preweaning phase.

The AAA $Values encompass the revenue generated from genetically derived outputs and associated costs (expenses) from required inputs.  The Weaned Calf Value ($W) considers four primary economic impact areas: (1) birth weight and calf death loss adjustments to cow profitability, (2) weaning weight revenue and expenses, (3) maternal milk, and (4) mature cow size expense adjustments.

“Weaned Calf Value pulls together key preweaning genetic factors into a business-minded dollars and cents selection tool,” says Sally Northcutt, AAA Genetic Research Director.  Northcutt reminds producers that the $W can be used to compare or rank the genetic merit among animals for preweaning performance.

$Values are not new to the Angus breed.  Multi-trait selection for postweaning and carcass merit was simplified with the introduction of $Values Indexes for Feedlot Value ($F), Grid Value ($G) and Beef Value ($B) in the Association’s Spring 2004 National Cattle Evaluation (NCE).   With the Spring 2005 Evaluation, the Weaned Calf Value ($W) has been added to the suite of bio-economic values to include preweaning performance in expected dollar-per-head difference.   The Spring 2005 Angus Sire Evaluation Report may be viewed and sorted online at

The American Angus Association, with headquarters in Saint Joseph, Mo., is the world’s largest beef breed organization, providing programs and services to thousands of commercial producers and more than 34,000 members nationwide.
