BOLT
To have a better sense of
improvement in accuracies, we
ranked sires based on either
BOLT or Cornell EPDs for birth,
weaning and yearling weights.
Then, we compared the progeny
performance of the top 1% vs
bottom 1% ranked sires for each
trait in each evaluation system.
The results are shown in Table 2.
As you can see, the BOLT EPDs
ranked sires more accurately
than EPDs from the Cornell
software, where progenies of
top 1% ranked sires based on
the BOLT EPDs are +3.1, +16.8
and +40.2 lb. heavier at birth,
weaning and yearling. These
results are exciting, and show
that our investment in new
technology will lead to more
accurate EPDs. I
