Sell at weaning, or feed them 60 more days? The value-of-gain math at record prices.

The calves are weaned, they are eating, and the neighbor sold his last week for a number that made you check it twice. The question is whether to haul yours now or put another 150 pounds on them and sell in December or January. It is a math problem with three numbers, and two of them are on the sale barn report.

The price slide

Lighter calves bring more per pound than heavy ones, because the buyer is paying for the pounds you have not put on yet. That is the price slide, and it means the last 200 pounds of a calf are never worth what the first 500 were. On a recent report, a representative market looked like this:

• 500-pound steers: $400 a hundredweight, or $2,000 a head.
• 600-pound steers: $365, or $2,190.
• 700-pound steers: $330, or $2,310.

Those numbers change every week and every region; pull your own from the barn you sell at or from the USDA Market News report for your state.

Value of gain

The value of gain is not $4 a pound. It is the difference in total dollars per head between the weights, divided by the pounds added:

• From 500 to 600 pounds: $2,190 minus $2,000 is $190 for 100 pounds, or $1.90 a pound.
• From 600 to 700 pounds: $2,310 minus $2,190 is $120 for 100 pounds, or $1.20 a pound.
• From 500 to 700 pounds: $310 for 200 pounds, or $1.55 a pound.

Notice that the second hundred pounds is worth much less than the first. The steeper the slide, the faster the value of gain falls. In a market where the heavy calves are catching up with the light ones, the value of gain climbs; in a market where buyers are chasing light calves for wheat pasture, it drops.

Cost of gain

What it costs you to put a pound on a weaned calf depends on the feed and how fast they gain:

• Grazing stockpiled fescue or wheat pasture with a little supplement: 1.5 to 2 pounds a day, at $0.50 to $0.90 a pound of gain counting the grass at a fair rent, mineral, and the supplement.
• Hay and a grain or distillers supplement in a dry lot: 1.5 to 2.5 pounds a day, at $1.00 to $1.40 a pound at current hay and corn prices.
• A full growing ration aiming for 3 pounds a day: $1.10 to $1.50 a pound, and you are competing with a feedlot at that point.

Add interest on a $2,000 calf for 60 days, which at 8 percent is about $27 a head, and death loss, which is 1 to 2 percent in a well-run backgrounding pen, or another $20 to $40 spread across the group. And add your labor, if you are honest.

Putting it together

A 500-pound calf, 60 days on stockpiled fescue with a pound of distillers, gaining 1.75 pounds a day: 105 pounds added, ending at 605 pounds. Value of gain at $1.90 is $200. Cost of gain at $0.80 is $84, plus $27 interest, plus $30 for death loss and health, is $141. Net $59 a head. Worth doing, if you have the grass.

Same calf in a dry lot on $200 hay and $5 corn, gaining 2 pounds a day: 120 pounds added, ending at 620. Value of gain about $210. Cost at $1.25 is $150, plus interest and death loss, $207. Net $3 a head. Not worth the risk or the work.

Now push both to 90 days, ending near 700 pounds, and the value of gain on the last 100 pounds drops to $1.20. The grass calf still nets something; the dry-lot calf loses money.

When the answer is sell now

• No cheap forage. If the gain has to come from purchased hay and corn, the numbers rarely work at today's slide.
• A steep slide. When the barn is paying $80 more for the 5-weights than the 7-weights, the market is telling you it does not want you to feed them.
• Cash. A $2,000 calf in the pen is a $2,000 loan you are carrying. If the operating note is due, the calves are the payment.
• Risk. Sixty days is a WASDE, a Cattle on Feed report, a tariff headline, and a winter storm. LRP can cover the price side; nothing covers the storm.

When the answer is feed them

You have stockpiled grass or wheat pasture, the calves are healthy and preconditioned, the slide is moderate, and the winter market has historically paid you for a heavier, greener calf in January. That is most fescue-belt and southern Plains operations in a normal year. Run the numbers with this week's report, not last year's, and run them again in 30 days. The math changes faster than the calves do.
