Why does winter feeding need a plan?
Grass stops growing in cold weather, and animals depend on stored feed until spring. Running out in February is stressful for animals and expensive for you, since emergency feed can be hard to find.
Start by estimating the length of your feeding season. Ask neighbors and your extension office how many weeks pastures usually stop supporting animals in your area. A written feed plan taped inside the barn door helps everyone who feeds know what, how much and when. Cold-weather feeding also changes with your animals. Pregnant or nursing females, young stock and older animals often need more attention than healthy adults, so ask your vet about each group.
How do I estimate how much feed I need?
Feed need depends on species, size, age, stage of production, weather and feed quality. There is no single figure that works for every farm.
Ask your extension livestock specialist or veterinarian for guidance on intake for your animals, and add a margin for waste and a long winter. Keep records of what you used each year.
Weigh or count bales when you buy them and track how fast the stack goes down. If you do not know the weight of your bales, weigh a few. Bales of the same size can differ by a lot depending on the hay and how it was baled. Make a simple chart with animal groups across the top and weeks of winter down the side, and fill in feed by group. It shows where your plan runs short before you are in the middle of it.
- Species, size and age
- Stage of production, such as pregnancy or growth
- Quality of hay
- Weather and wind
- Waste during feeding
What counts as good winter feed?
Hay quality varies widely. Good hay is leafy, clean, smells fresh and is free of mold and dust. A forage test through a lab can tell you more about quality than looks alone, and your extension office can explain how to take a sample.
Some animals need extra feed or mineral supplements in winter or late pregnancy. Ask your veterinarian or extension nutrition specialist what is right for your herd or flock.
Change feed gradually to avoid digestive upset. A forage test costs little compared with the feed it describes, and the result may show that your hay is better or poorer than it looks. Avoid feeding moldy or frozen feed and avoid sudden jumps in grain or rich feed, which can upset digestion. Your vet can explain safe transitions for your species.
How do I judge body condition?
Check animals by hand as well as by eye, since winter coats and wool hide thin bodies. Learn the body condition scoring method for your species from extension or your vet, and check regularly.
Animals that are losing condition, even though they seem to be eating, may have worms, bad teeth or other health issues. Call your veterinarian rather than guessing.
Separate animals that are being bullied away from feed. Ask for hands-on practice from your vet or an experienced keeper, since scoring is easier to learn by feel than from a chart.
What about water and shelter in winter?
Animals that cannot get unfrozen water will eat less and risk illness, so keep water open and clean. Cold, wind, wet and mud all increase the energy animals need.
Provide dry bedding, a windbreak and a place out of the wind. Ask extension what shelter suits your species and your climate.
Keep animals off deep mud, which harms hooves and wastes feed. If you have no barn, a simple three-sided shed with the open side away from the wind helps a lot. Keep bedding dry and clean.
How do I reduce hay waste?
Waste can be large when hay is thrown on the ground, trampled or left in rain. Feeders, racks or a set feeding area can reduce it, as long as they are safe and do not trap animal heads.
Feed only what animals will clean up in a reasonable time, and keep the feeding area clean. Rotate feeding spots to reduce mud and manure buildup. A feeder that animals can crowd around can lead to injury, so give enough feeding space that low-ranking animals can eat.
When should I call for help?
Call your veterinarian if animals are weak, losing weight, off feed, bloated, down or showing any sign of illness. Cold-weather problems can become serious quickly.
If you run short of feed, call your extension office, neighbors or local feed suppliers early. Do not wait until the barn is empty. Keep a list of numbers by the barn phone: your veterinarian, your extension office and two hay suppliers. Cold snaps and storms can cut off roads, so keep a few days of spare feed in reserve.
Key takeaways
- Plan winter feed before winter starts.
- Estimate need from local advice and your own records.
- Test hay when you can and check body condition by touch.
- Provide open water, shelter and dry footing.
- Call your vet early when animals lose condition.
