Eligibility for Publication<br />
Progeny Proven <strong>Sire</strong>s<br />
To be eligible for publication in <strong>the</strong> <strong>CCA</strong> <strong>Sire</strong><br />
<strong>Summary</strong>, a bull must:<br />
1) have had at least 10 calves with CHARM weaning<br />
records in <strong>the</strong> last 3 years.<br />
2) meet an accuracy standard of .50 in <strong>the</strong> weaning<br />
weight EPD evaluation.<br />
Weaning weight is used as <strong>the</strong> selection criteria as it is<br />
least subject to bias and is <strong>the</strong> trait that is best<br />
represented across herds and sires. EPD and accuracy<br />
values are published for all traits for <strong>the</strong> sires selected.<br />
All sires listed in this section have enough<br />
performance-tested progeny to be considered as<br />
predictable.<br />
<strong>Interpreting</strong> <strong>the</strong> <strong>Sire</strong> <strong>Summary</strong><br />
Young <strong>Sire</strong>s<br />
To be eligible for publication in <strong>the</strong> <strong>CCA</strong> <strong>Sire</strong><br />
<strong>Summary</strong> a young bull must:<br />
1) be born on or after January 1, 2002.<br />
2) have an accuracy of .35 or greater for weaning<br />
weight EPD.<br />
3) have had at least 2 calves with CHARM weaning<br />
records.<br />
Young sires with higher accuracies (.50 or greater) may<br />
also appear in <strong>the</strong> progeny proven section. This section<br />
is intended to provide information on young sires with<br />
potential for use in breeding programs. The EPDs<br />
expressed should be carefully considered as some<br />
accuracies may be fairly low.<br />
Trait Leaders<br />
Active Progeny Proven sires identified from <strong>the</strong> bull<br />
evaluation as trait leaders are those that excel in a<br />
specific trait. To be selected for <strong>the</strong> trait leader<br />
designation a bull must meet superior standards for<br />
both <strong>the</strong> EPD and <strong>the</strong> accuracy of <strong>the</strong> trait in question.<br />
The sires designated as (TL) throughout <strong>the</strong> proven<br />
section include <strong>the</strong> top 25 for each trait based on EPD<br />
values with accuracy values of .75 or greater for birth<br />
weight and weaning weight and .65 or greater for<br />
yearling weight and total maternal, and .60 or greater<br />
for <strong>the</strong> Milk EPD. Ties for any trait were broken by<br />
taking <strong>the</strong> animal with <strong>the</strong> higher accuracy first.<br />
