$VALUE INDEXES
Weaned Calf Value
($W)
an index value, expressed in dollars per head, is the expected
average difference in future progeny performance for preweaning
merit. $W includes both revenue and cost adjustments associated
with differences in birth weight, weaning direct growth, maternal milk
and mature cow size.
Feedlot Value
($F)
an index value, expressed in dollars per head, is the expected
average difference in future progeny performance for postweaning
merit compared to progeny of other sires.
Grid Value
($G)
an index value, expressed in dollars per head, is the expected
average difference in future progeny performance for carcass grid
merit compared to progeny of other sires.
Quality Grade
($QG)
represents the quality grade segment of the economic advantage
found in $G. $QG is intended for the specialized user wanting to
place a higher emphasis on improving quality grade. The carcass
marbling (Marb) EPD contributes to $QG.
Yield Grade
($YG)
represents the yield grade segment of the economic advantage found
in $G. $YG is intended for the specialized user wanting to place more
emphasis on red meat yield. It provides a multi-trait approach to
encompass ribeye, fat thickness and weight into an economic value
for red meat yield.
Beef Value
($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.

The Bulls that Sell
The bulls were tested again this year on our GrowSafe
System, using the Purina Impact Beef Grower Ration with
12% ground hay added on the spring calves. Feed efficiency
information gathered on the GrowSafe System is listed
on each bull’s pedigree. At the bottom left of this page are
explanations of feed efficiency outputs with a more in-depth
explanation on page 6. After coming off test, the bulls were
turned out on a 110 acre pasture and fed a corn silage/rolled
milo maintenance ration with free choice hay.
The bulls have been checked for breeding soundness and
tested for BVD/PI by Dr. Niederee, from the Countryside Vet
Clinic in Great Bend. He will be on hand sale day to answer
any questions you might have about our herd health program.
All bulls are guaranteed against breeding injury for the
first breeding season.
If a replacement is needed, one will
be provided depending on availability. If a replacement is not
available, credit may be given in our next bull sale.
Each lot includes the animal’s EPDs and how they performed
on test ( ADG, DMI, RFI, F:G). Below their pedigree you will
find their actual performance weights and ratios. Yearling
weights, ultrasound measurements and body composition
scores were done by Dr. Paul Ritter.
At the bottom of each lot is the animal’s 50Ki percentile
rank. All bulls selling have been parent verified and tested free
of any known genetic conditions and defects.
We have also included both the actual birthweight and the
age of the dam on each lot. The reason for doing this is to give
you the opportunity to convert birthweights to a two-year-old
basis using the chart below.
5 year old cow through 10 years of age Subtract 6.7 lbs.
4 year old cow through 5 years of age
Subtract 5.6 lbs.
3 year old cow to 4 years of age
Subtract 4.1 lbs.
2 1/2 year old cow to a 3 year old
Subtract 2.5 lbs.
2 year old to 2 1/2 year old
Subtract 0 lbs.
For example, take a 5 year old cow that has had an 80
pound calf. To covert this calf’s weight to a 2-year-old basis
you would subtract 6.7 pounds. In other words, the same calf
out of a 2 year old heifer would have weighed 73 pounds.
Videos of the Sale Bulls will be available for viewing on our
website the week before the sale. If you are unable to attend
Sale Day, please register with DVAuction by Friday
March
31st
so you can participate in our live internet bidding.
Feel free to come view the bulls the weekend
before the sale at Elizabeth and Dustin’s

Feed Efficiency Data Outputs
ADG
(Average Daily Gain)
This value describes an animal’s genetic potential for postweaning
rate of gain. Directed toward the feedlot period,
a higher value
indicates a higher average daily gain.
DMI
(Adjusted Dry Matter Intake)
This is defined as the feed dry matter intake adjusted by multiplying
the contemporary group’s average mid-point metabolic weight, and
then dividing by the individual’s mid-point metabolic weight. The final
value is the difference by subtracting out the contemporary group
average.
A lower value is desired.
RFI
(Residual Feed Intake)
This is defined as the difference between actual feed intake and
that predicted on the basis of the animal’s gain and maintenance
requirements for its body weight. An average animal would have an
RFI of “0”. Animals with a negative RFI value are favored because
they have consumed less feed for their weight and gain, than the
average of their herd mates. Animals with a positive RFI number
would be consuming more feed for their weight and gain, than the
average of their herd mates.
A negative value is desired.
F:G
(Adjusted Feed Conversion)
This value is the base Feed:Gain ((F:G) = pounds of feed (on a 100%
dry matter basis) required for one pound of live weight gain) value
multiplied by the contemporary group’s metabolic weight divided by
the individual’s metabolic weight.
A lower value is desired.
