we look for is a low birth
weight (the weight of the bull
at birth), because a high birth weight
can be passed down to its offspring,
resulting in a larger calf that will be
more diffi cult for the cow to birth. We
generally look for a birth weight under
eighty-fi ve pounds if we are going to
put the bull out with our cows who
have already had at least one calf.
If we are looking for a bull for our
smaller, younger replacement heifers,
we will look for as low a birth weight
as possible. Also, we look for a smaller
bull to match the size of the heifers.
When we are looking at bulls we
consider their EPDs (Expected Progeny
Differences), which is a calculated
number that allows you to compare the
genetic traits of the animal to others of
the same breed. We look for the bulls
with good numbers for birth weight,
weaning weight, and calving ease.
Selecting new bulls for our herd is
one of the many parts of ranching that
I enjoy. When our cows calve in the
spring, it is very rewarding to see the
calves that the new bulls fathered!
While out riding to check their cows,
Julia snapped this shot of a couple of
their bulls enjoying the green pasture.
MELINDA SIMS WYOMING
his is Kagan (16)
and Jentry (13)
Sims with their
BQA certifi cates! I
was able to snap a
shot of Jentry in the middle
of the modules. Very diligent
kids - both sat down in an
afternoon and wouldn’t stop
until it was done and both missed 2 questions on their fi rst try so both
HAD to retake to get 100% (EDITOR: Great job, kids ...um, I missed a
couple questions, too, and had to retake it, so...and don’t tell Tigger). The
age requirement is 18 or older, but a quick call to our Wyoming extension
head got an OK for them to take it.
