Do These Cattle Work?

We ask ourselves this question nearly every day. And, we don't always have time to fire up our computer and run a projection to answer the question. So it is helpful to have a feel for what kind of cost of gains are associated with various feed prices as well as feeder wrights. While you cannot be completely accurate without running a projection, you can get close enough to be helpful if you keep a few things in mind.

Right now, most cattlemen in my area are using $4 on corn since it has up a bit in the last while. In general, if you are using $4 corn and $85 on modified distillers and around $65 on wet distillers (which equates to around $160 DDG), your cost of gain on a 600-lb steer is going to be around $79-80/cwt. This figure includes feed, yardage and interest.

From there you just need to know the market weight, let's say 1450-lb. So 1450–600 = 850 lb of gain.

Multiply 850x$0.80 COG and you have $680. So if your 600-lb steers cost $275/cwt, you have $1650 invested in the feeder. Adding $680 + $1650 = $2330 total investment.

So now we can divide $2330 by 1450 lb and come up with our break-even of $160.69/cwt.

This simple calculation gets done every day. Once you establish that the cost of gain on 600-lb steers is $80/cwt of gain, you can vary from there based on body weight and corn price.

In general, for every plus or minus 25¢ on corn price, cost of gain will go up or down about $2/cwt. And for every plus or minus 100 lb of feeder weight purchased, your cost of gain will go up or down about $3/cwt.

Heifers cost of gain will be about 10% higher than comparable steers.
