Least-Cost Winter Feeding

The goal in winter is not the cheapest feed. It is the cheapest feeding program that keeps cows in the condition they need for calving and rebreeding.

Key points

Least-cost means meeting needs at the lowest total cost, not the cheapest feed.
Test hay and label each lot.
Group cows by need so you do not overfeed or underfeed.
Cut waste with simple feeding changes.
Check cow condition on the 1 to 9 scale during winter.

What least-cost really means

A low feed bill that leaves cows thin is false economy. Thin cows calve harder, milk less and rebreed late, and those costs show up the next year. Least-cost feeding means meeting the cow's needs with the lowest total cost, including labor, waste and the effect on production.

That starts with knowing what the cows need and what each feed delivers.

The aim is a cow that calves in good condition and rebreeds on time without costing more than she has to.

Start with a forage test

Hay looks similar from the road and can differ a lot in feed value. A forage test tells you what each lot supplies, so you can see whether it covers the cows' needs or leaves a gap.

Test each lot and cutting separately and label them. Then you can feed good hay to cows with the highest needs and poorer hay to those that can use it.

Ask the lab or your extension office how to read the report, especially for protein and energy measures, so you know what the numbers mean for your cows.

Group cows by need

A mature cow in good condition in mid-gestation needs less than a first-calf heifer or a thin cow. Feeding everyone the same wastes feed on some and shortchanges others.

Where you can, split the herd:

Heifers and thin cows may do better on better hay, while mature cows in good flesh can often be held on lower-quality feed. Moving groups as conditions change takes a little work and pays back.

Cut waste where it is cheapest to cut

Hay fed in the open can be trampled, soiled and left behind. Feeders, limiting the amount fed at a time, unrolling only what cows will clean up, and keeping bales off wet ground all cut losses. The right method depends on your equipment, weather and labor, and the cheapest fix is often a small one.

Watch what is left in the field after feeding. Leftovers are money.

Even simple tools help. Ring feeders, hay racks and rationing the daily amount all cut waste compared with leaving bales out for weeks, though each has its own cost.

Use stockpiled forage and crop residue wisely

Stockpiled pasture, standing corn stalks or other residues can stretch the feeding season at low cost if the quality matches the cow's needs. Quality can be low, so ask your nutritionist whether cows will need supplement to go with it.

Strip grazing or limiting access to fresh forage helps cows use what is there without trampling it. Check with your extension office about local options.

Cold weather raises a cow's needs, and wind and wet make it worse. Shelter and bedding can lower the feed it takes to keep her in condition.

Supplements: buy by need, not by habit

Supplement should fill the gap your forage test shows, nothing more. Compare products by what they supply per dollar rather than by bag or load price, and ask your nutritionist to check your numbers. Any feed additive must be used by label and with advice from your vet or nutritionist.

Make feed changes gradually, and make sure water does not freeze, because cattle that cannot drink will not eat well.

Always check the supplement label and follow the directions, and watch for cattle that eat too fast or too much and need a gradual introduction.

Common mistakes and what to ask

Frequent mistakes include buying hay on looks alone, skipping a condition score until calving, feeding the whole herd as one group, ignoring waste and letting water freeze. Ask your nutritionist or extension agent to review your tests, groups and plan before winter starts. Your lender or accountant can help with cash flow, and prices and program terms change, so ask for current information.

Keep a winter log of feed delivered, weather and cow condition. At the end of the season, compare what you planned with what happened and write down one change for next year.

Neighbors and extension groups often share feed and equipment ideas that fit your area, and a short conversation can turn up a cheaper option you had not considered.

When to get help: Ask a nutritionist or extension specialist to review forage tests and group feeding plans, and call your veterinarian about cows that lose condition despite adequate feed.
