Winter Care for Alpacas: Cold, Snow, Water and Feeding

Alpacas evolved in the freezing nights of the high Andes, and their fleece is a superb insulator. Cold rarely bothers healthy adults — wind, wet and ice are the real dangers, along with hidden weight loss and frozen water.

Shelter

• A dry, draft-free three-sided shelter facing away from the wind is usually enough. See shelter design.
• Add windbreaks (solid panels, hay bales, tree lines) in exposed sites.
• Provide deep straw bedding for crias, seniors and thin animals.
• Keep ventilation — closed, damp barns cause respiratory disease.

Feeding in winter

• Fermentation of fiber in the fore-stomach generates heat. Feed more hay — free choice — especially before cold nights.
• Energy needs rise as temperatures drop; thin, old, pregnant and lactating animals may need a camelid pellet or beet pulp.
• Stock enough hay before winter: use the winter hay calculator, and see your county’s hay estimate in the local guides.

Water

• Use heated buckets or tank de-icers, with cords protected from chewing.
• Break ice at least twice a day if you don’t have heaters.
• Lukewarm water encourages drinking.

Body condition

Fleece hides weight loss. Every 2–4 weeks, feel along the backbone and ribs under the fleece and score each animal (aim for 3 out of 5). See the body condition guide.

Vitamin D for crias

In northern regions (roughly above 35–40° latitude), winter sunlight is too weak for vitamin D production. Crias and young alpacas — especially dark-fleeced ones — are at risk of rickets. Ask your vet about vitamin D supplementation from autumn to spring.

Snow and ice

• Alpacas often lie in snow comfortably; snow on the back shows good insulation.
• Ice is dangerous: spread sand or straw on paths and around feeders.
• Clear snow from shelter roofs to prevent collapse.

Cold-weather risks

• Frostbite of ear tips and scrotum in extreme wind chill. See frostbite.
• Hypothermia in wet newborn crias — avoid winter birthing where possible. See hypothermia in crias.
• Recently shorn animals need shelter and sometimes coats if a cold snap follows shearing.
• Coats help crias, seniors and thin animals — but remove them on sunny days to avoid sweating.

Winter checklist

• Water heaters installed and tested
• Hay stocked and covered
• Windbreaks and shelters repaired
• Body condition scored monthly
• Vitamin D plan for crias
• Toenails trimmed before ground freezes

Frequently asked questions

How cold is too cold for alpacas? Healthy adults with shelter tolerate well below 0°F (-18°C). Wind, wet and poor body condition are what make cold dangerous.

Do alpacas need blankets in winter? Usually not. Coats help newborn crias, seniors and thin or recently shorn animals.
