As a reminder for weaning time, cow weights with a body condition score need to
be taken +/- 45 days of the calf's weaning measure date. Cow hip heights may be
captured at this time, also. It is important to collect this information after the
cow has weaned her first calf, and then again in subsequent years.
A body condition score must be included with the cow weight in order
for data to be utilized to calculate mature size EPDs in the National Cattle Evaluation.
Any cow weights submitted without a body condition score will not be used.

The American Angus Association generates mature size EPDs that utilize cow weights
and heights on breeding females, as well as their yearling measures (submitted on
the AHIR yearling report form). The Mature Weight EPDs and the Mature Height EPDs
are also used in the $Value index calculations for Weaned Calf Value ($W) and Cow
Energy Value ($EN).
