When Buying Cows
By Kris Ringwall, Extension Beef Specialist,

This is the time for good cow sales and the $64 question is: How do you
determine what a good cow is worth?
The classic answer is whatever the highest bidder will pay. But there is more
to the true value of a good cow. The value should reflect the demand and supply
status of the cattle cycle. If these principles are ever in doubt, you only need
to visit the public auction livestock facilities.
While demand and supply may drive the price, the value of a good cow is based
on what a good cow can produce.
Often cows are sold based on breed type, size, or age with very little real
evidence of expected performance or potential output. Knowing what a particular
cow will produce is difficult without adequate individual performance data.
Data collected in the CHAPS program through the North Dakota Beef Cattle
Improvement Association gives us a look at how some of the age groups of cows
that are enrolled in the program have performed. These averages are not for the
purpose of indicating what one can pay for cows, but only an indication of
average performance differences between cow ages. Also listed is the typical
loss or cull rate of each age group (what percent of these cows will not be back
next year to calf again). The reason why cows left is not noted, only the fact
that the cows are no longer present in the herd.
A typical two-year-old cow in this data set produced a 561-pound calf with a
14 percent loss (cull) rate. (Two year old weights are adjusted to mature cow
calving dates.) If you buy bred two-year-olds, the CHAPS data would indicate
that 14 percent of those cows will be in the sale ring within the year, although
they did wean 561-pound calves. In general, data suggests calf weaning weight
increases until cows reach seven years of age, reaching a maximum of 580 pounds.
Calf weight decreases slightly faster than it increased.
The loss (cull) rate of cows seems to be around 10 to 15 percent when buying
seven-year-old cows or younger. It is quite another story when you start buying
eight-year-old cows or older. If you are buying cows, you will want to factor
these statistics into your purchase price equation. Keep these following facts
in your pocket book.
The following are the respective calf weights and cow loss rates for all the
- Three-year-old cows produced 538 pounds of calf with a 16 percent loss
- Four-year-old cows produced 560 pounds of calf with a 9.5 percent loss
- Five-year-old cows produced 574 pounds of calf with a 10 percent loss
- Six-year-old cows produced 578 pounds with a 13.7 percent loss rate.
- Seven-year-old cows produced 580 pounds of calf with a 14.6 percent loss
From this point on calf weight weaned decreases and the loss rate of the cows
increases. A typical 14-year-old cow produces 518 pounds of calf with a loss
rate of 66.7 percent.
Watch what you pay for old cows.
May you find all your ear tags.
