ANGUS BULL BUYER’S REFERENCE
Birth Traits
CED – A higher number, more calving ease. BW – A lower number, a smaller calf. Act. BW – Ratioed and incorporated into the EPD.

Industry Trend, is Great numbers of Angus sires are reaching extremely high CED and low BW EPD values, largely due to highly heritable shorter gestations lengths. We do not see it as a positive trend when calves become to small at birth. In addition, none of these birth traits measures calf vigor of a sire’s progeny and mothing ability of the cow line. We do that for you.
Performance Traits
WW – Weight adjusted for age of dam to 205 days, ratioed in contemporary group and incorporated into WW EPD.
YW – Weight adjusted to 365 days, ratioed in contemporary group and incorporated into YW EPD.
Industry Trend, is fascinated with chasing extremes of WW EPD and YW EPD to the top percentiles of the breed, and selection pressure will move them higher. Long-term customers that retain ownership through the feedlot have no problem producing 1450-1500# pay weight steers from bulls that range from +90 (top 55%) to +121 (top 10%) of the breed.We believe this selection criteria will help us and our customers control cow size and cow maintenance requirements and therefore cow herd costs.
Maternal Traits
Milk – is a predictor of a sire’s genetic merit for milk and mothering ability as expressed in his daughters compared to daughters of other sires. In other words, it is that part of a calf’s weaning weight attributed to milk and mothering ability.

$Value indexes, are multi-trait selection indexes to assist beef producers by adding simplicity to genetic selection decisions. $Values are reported in dollars per head, where a higher value is more favorable. The $Value is an estimate of how future progeny of each sire are expected to perform, on average, compared to progeny of other sires in the database if the sires were randomly mated to cows and if calves were exposed to the same environment.
Weaned Calf Value ($W) – an index value expressed in dollars per head, is the expected average difference in future progeny performance for pre- weaning merit. $W includes both revenue and cost adjustments associated with differences in birth weight, weaning direct growth, maternal milk, and mature cow size.
Beef Value ($B) – an index value expressed in dollars per head, is the expected average difference in future progeny performance for postweaning and carcass value compared to progeny of other sires.
