Culling Strategies for Profit

Every cow on the place either pays her way or costs the ranch money. Culling is how you keep the herd made up of cows that earn their keep.

Key points

Cull open, unsound and unproductive cows consistently.
Use records, not memory, to find the real underperformers.
Do not cull on a single poor year.
Follow withdrawal times and transport rules for every cull animal.
Keep enough replacements ready to hold herd size.

What culling is for

Culling means removing animals from the breeding herd. Some leave for clear reasons, like failing to breed or becoming unsound. Others leave because their calves are consistently below the herd average. A good culling plan keeps the herd productive and sound.

It also keeps your replacement program honest. If you never remove poor cows, you cannot improve the herd through the heifers you keep.

Set a culling routine at the same time each year, such as at weaning or at the pregnancy check. A routine takes the emotion out and makes the decision part of normal work.

Reasons that nearly always apply

Some reasons are widely accepted among ranchers. Open cows after the breeding season are the clearest case, since the cow-calf business depends on one calf per cow per year. Others include unsound feet, legs or eyes, bad udders, serious temperament problems and repeated calving trouble.

Ask your vet to help you judge a questionable animal. Not every problem is permanent, and not every cow that looks rough is a poor producer.

Age by itself is not a reason to cull. An older cow that raises a good calf every year is valuable, so look at her record and her soundness, particularly her teeth, feet and udder.

Open at pregnancy check
Unsound feet, legs or eyes
Poor udder or teat structure
Dangerous temperament
Repeated calving difficulty
Chronic health problems
Late or inconsistent calving

Use your records

Records turn opinion into evidence. Track calving date, calf weight at weaning, health events and any problems for each cow. A cow that calves late or weans light year after year is costing you money even when she looks fine in the pen.

Weaning weights adjusted to the standard 205-day basis help you compare cows fairly. Your extension office or breed association can show you simple record systems.

A simple notebook, a tag number on every cow and a few notes at each working day will do. The best system is the one that you will actually keep up.

Consider the bigger picture

Do not cull on one bad year. A drought, a hard winter or a poor calf crop can hide a good cow's real record. Look at several years when you can.

Think about how many replacements you can raise and what the grass can support. If you cull more cows than you can replace, the herd shrinks. If you cull too few, quality slips.

Talk to your lender and accountant about the cash effect. Selling many cows in one year can raise taxes and shrink income in the following years.

Timing the sale

Cull cow prices move through the year, and market conditions change. Talk to your sale barn, buyers and market reports from USDA AMS about seasonal patterns, but do not count on timing to rescue a poor decision.

Cows that are in good condition at sale tend to be worth more than thin ones. Where it fits your plan, ask your nutritionist whether short feeding before sale makes sense for your cattle.

Handle cull cows quietly and haul them with care. Rough handling and long waits cause bruising and stress, and they reduce value.

Welfare, health and meat safety

Cull animals still go into the beef supply, so health and treatment records matter. Any treated animal must meet the withdrawal time on the label or set by your vet before sale for slaughter, and residue avoidance protects the whole beef supply.

Do not ship an animal that is too sick, injured or weak to travel safely. Talk to your vet about animals that are not fit to transport, and follow Beef Quality Assurance guidance on handling and transport.

Mistakes and what to ask

Common mistakes include keeping a favorite cow with a poor record, culling on a single bad year, selling without checking treatment records and failing to keep replacements ready. Another is skipping pregnancy checks.

Ask your vet which animals are truly unsound. Ask your accountant how cull sales affect your taxes. Ask your buyer what condition makes cows sell best.

When to get help: Ask your veterinarian to help judge soundness and health, your extension office about record systems, and your accountant about tax effects of cull sales. Follow label and vet withdrawal times exactly.
