There are as many good methods of measuring cattle as there are good cattlemen.
We measure our cattle in order to improve them. It is our goal as BueLingo breeders to produce
the perfect beef animal.
The following two tables are from the "
Standards of Perfection
" adopted at the Buelingo Beef Cattle Society's 2000 convention. The numbers are
the Society's recommendations and were arrived at in consultation with Mr. Gerald Fry using the goal
of an 1,100 pound finished animal grading "choice". They are intended to be used as guidelines for breeding
stock. You should notice that standards specify a range of values rather than a single "ideal"
number. This allows producers to fit these numbers into their local conditions. Numbers can be helpful
tools in selecting and breeding for the kind of animals you want to produce. But everyone should keep
in mind that numbers are only tools, and not magic.

Produce a "Choice" market heifer or steer weighing at least 1,100 lbs. in 18 months or less.

We are using the calculations of "Frame Score" and "Adjusted 205 Day Weight" as
defined in the Beef Improvement Federation's (BIF) handbook "Guidelines For Uniform Beef Improvement
Programs" Sixth edition. In the handbook there are breed specific adjustment numbers
defined by the BIF and the various breed organizations. However, this is the BueLingo Cattle
Society's website and we will use the "Standard" BIF adjustments which the BIF says are the ones
appropriate for our breed. For more detailed explanations, please feel free to read the BIF handbook
documents on
Live Animal Evaluation,
Frame Scores
, and
Adjusted 205 Day Weights
.
Frame score is a complicated mathematical formula which yields a simple
single digit estimate of the animal's hip height at 18 months of age. It was invented by Prof. John Massey,
University of Missouri and it allows feed lots to estimate the finished weight of an animal.

WEIGHT AT CHOICE
FOR VARIOUS FRAME SIZES
STEERS

An animal with a higher frame score is taller at the hip than one with a lower frame
score. Frame score describes the size/maturity of an animal. It also tells us something about how long
it will take for that animal will reach its finished weight. The higher the frame score, the longer
it takes for that animal to finish and the higher its finished weight will be. The longer that animal
is on feed, the higher the total feed costs will be. Large frame cows require more feed for maintenance
than do smaller framed cows.
The formula used works correctly only for cattle between 5 and 20 months of age. There
are formulas which adjust the hip height measurement to 205 or 365 days of age. There is also a chart which
gives the frame score for older animals. Most animals should maintain the same frame score throughout their
life, though their actual height will continue to increase.
The BIF does not calculate the frame score out to the nearest tenth (although it is a common
practice.) As a practical point, it is often difficult to obtain accurate height measurements. Cattle
must be measured between the hips to a point on the spine, but often this does not happen. Cattle
must be standing upright and on level ground. Also, angulation of joints affects height. For example
cattle with very straight hindlegs may have the same skeletal size as sickle hocked animals but they
measure taller. Finally, nutrition can contribute to a half score variation in frame score either way.
The recommended point of measurement for hip height is directly over the hooks.
Height Measurement
For some discussion on the proper use of frame scores see the article "
The Usefulness of Linear Measurements to BueLingo Breeders
" by Mr. Russell Danielson, of the Animal Science Department of North Dakota State University. Mr.
Patrick Goggins has a good discussion of frame scores in "
As I See It - Where are we Going on Size?..." Another good page to visit is Kansas
State's ASI page "
Animal Breeding Information Using the Frame Score Charts".
Also see "
Don't Be Highjacked by Frame Score
" from the Australian Simmental Breeders Association. And take a look at "
Frame Scoring of Beef Cattle" from NSW Agriculture. Both of these last two sites are Australian
so American readers will need to remember that there are 2.54 cm in 1 inch and 2.68 pounds in 1 kg.
Adjusted 205 Day Weights are a simple calculation, taking a calf's age at
weaning and its weaning weight to estimate what it should have weighed at precisely 205 days of age.
This allows a direct comparison of the growth rate of calves born at different times.
The birth weight is subtracted from the measured weight and a daily rate of gain is
calculated. Multiplying this daily rate of gain times 205 days gives the expected total gain and
adding back in the birth weight gives the unadjusted 205 day weight. The adjustment is the extra
weight added to compensate for the age of the Dam. Cows less than 5 years of age and cows older than
10 aren't expected to allow their calves to fully express their genetic potential and the adjustment
is to make up for that.
