Winter Feeding Strategies for Beef Cattle

Winter feeding is usually the biggest cost on a cow-calf ranch. A plan made in fall, based on tested hay and honest condition scores, keeps cows healthy without waste.

Key points

Take a feed inventory and test hay before winter begins.
Sort cattle by condition and stage so each group gets what it needs.
Plan for cold and wet weather, shelter and water.
Use a nutritionist or extension specialist to balance rations.

Start with an inventory

Before cold weather, count your hay and other feed and compare it with how many cattle you will feed and for how long. Allow for bad weather and a late spring. Running short in February is expensive and stressful.

Ask your extension office how to estimate hay needs and bale weights for your situation instead of relying on a guess.

Write your estimate down and update it each month. If the numbers are tight, you will know early enough to buy, cull or adjust, rather than finding out in the coldest week of the year.

Test the feed

Forage tests show what the hay actually offers in energy, protein and other measures. Without them, you do not know whether cows are getting enough or too much.

Have a nutritionist or extension specialist read the results and recommend what supplement, if any, fills the gap.

Hay from the same field can vary between cuttings and even between bales, which is why separate sampling pays off. Keep each lot stacked and labeled so you can match the feed to the test.

Send samples to a reputable lab
Keep results with the hay lot record
Rebalance if you change hay

Sort cattle by need

Not every animal has the same needs. Young cows, thin cows and late-pregnant cows often need more than mature cows in good condition. Sorting into groups lets you feed each group what it needs and avoids overfeeding some while others fall behind.

Score condition on the 1-to-9 scale before winter and again partway through. Move thin cows to a better ration before they drop further.

Weather, wind and energy

Cold, wet and windy weather raises how much energy cows need to stay warm. Windbreaks, dry bedding and shelter help. Ask your nutritionist how to adjust rations when the weather turns severe.

Mud saps energy and spreads disease, so keep feeding areas well drained and move feeders when ground gets torn up.

Calves, bulls and older cows have different needs and different tolerance for cold. Ask your nutritionist whether any group on your place needs special attention when the weather turns.

Feeding methods and waste

How you feed hay affects waste. Unrolling bales, ring feeders, bale processors and limiting access can reduce waste, though each has costs. Ask your extension specialist about the options that fit your operation.

Be sure every cow can reach feed. Shy or lower-ranking cows may be pushed away, so provide enough bunk or feeding space.

If you feed a supplement, make sure every cow can get to it. Competition at the feeder means the boldest cows get more than they need and the shy ones get little.

Water and minerals in winter

Water is easy to forget when it freezes. Cows that cannot drink do not eat well. Keep tank heaters safe and in working order, follow manufacturer and electrical safety guidance, and check water daily.

Keep mineral available all winter. Ask your nutritionist whether your winter forage calls for a different mineral than your summer program.

Tank heaters and extension cords are a common cause of barn and pasture fires and shocks. Follow manufacturer instructions and electrical safety guidance, and replace any worn cords before winter.

Common mistakes and what to ask

Common mistakes include not testing hay, feeding all cattle the same, ignoring weather, letting water freeze and buying feed in a panic.

Ask your nutritionist to help with a ration, ask your lender about financing feed if cash flow is tight and ask USDA FSA or NRCS about programs, remembering that terms change. Write down what you learned this winter while it is fresh, so next fall's plan starts from facts instead of memory.

Be ready to adjust partway through winter. Condition scores, hay test results and the weather will all change what the herd needs, and a plan that cannot change is a poor plan.

When to get help: Ask a nutritionist or extension specialist to read your hay test and balance a winter ration, and talk with your lender or USDA FSA if feed costs strain cash flow. Call your vet about thin cows or sudden illness.
