Winter Livestock Health Checklist
Posted by Grange Co-op on 4th Feb 2026
Shorter days, hard freezes and mud will put the care of your livestock to the test. As seasoned farmers know, your cattle’s nutritional needs don’t drop with the thermometer; they rise. A practical rule of thumb: for each degree the temperature dips below comfort range, maintenance requirements increase. In mid-cold conditions you might see a 2–8% bump in intake, and as much as 25% during extreme subzero spells. Horses, goats, and sheep follow the same logic—when it’s colder, they burn more energy to stay warm, so the ration and water plan need to keep pace.
This guide focuses on three things that move the needle in winter livestock care: water they will actually drink, hay that truly feeds, and minerals that match species and season—with a few species-specific notes to keep cattle, horses, goats, and sheep in good condition through winter.
Keep Water Warm, Keep Intake Up
Hydration drives intake, digestion, and body heat. When tanks ice over, animals drink less, which can spiral into reduced feed intake, slower digestion, weight loss, and weaker immune response. Keeping water near a comfortable temperature encourages steady drinking. Cattle may naturally reduce visits to water in harsh winter weather, so keeping water reliably thawed and easy to reach helps offset that behavioral dip.
In winter trials, beef cattle offered lukewarm water (~88 °F) drank about 30% more than cows offered near freezing water (~46 °F)—a big difference for maintaining intake in the cold. 1 *

Hardware that helps: Heated stock tanks, tank deicers, and heated buckets keep water thawed and palatable. Inspect cords and elements frequently and run them on GFCI outlets.
-
Maintenance that matters: Skim ice daily on open tanks, clean buckets/tanks weekly to remove slime and small feed/mineral particles and check floats/valves after hard freezes.
Hay Quality: Test It, Then Balance
Not all hay is created equal. Quality varies between fields and cuttings, and the differences matter more in winter when animals have fewer chances to graze selectively. A simple forage analysis tells you protein and total digestible nutrients (TDN) so you know what to supplement and when—no guessing, just better feeding.
-
Where to test: Start with the National Forage Testing Association or your local extension service. Basic tests often start around $35 and give you a solid read on protein and energy.
-
How to use the results: If your hay tests low in protein or TDN, plan to increase roughage volume on cold/windy days and add targeted energy/protein where the forage falls short.
-
Storage & handling: Keep hay dry, off the ground, and well ventilated. If intake drops or refusals increase, switch lots and reassess.
Protein, Energy & Pace of Intake
In winter, the rumen is a furnace—effective fiber that fuels internal heat. But when forage alone isn’t enough (late gestation, heavy lactation, or a deep freeze), add energy and protein strategically. Protein tubs are a convenient, low labor way to lift protein (and sometimes energy) without juggling multiple feeds. For horses and smaller ruminants, slow feed nets or feeder panels pace intake, reduce waste, and keep hay cleaner than in muddy pens.
Barn tested tips:
-
Step up roughage first during cold snaps; then layer in protein tubs or concentrates based on your forage tests and body condition goals.
-
Adjust gradually. Sudden ration changes can upset the rumen, especially in sheep and goats.
Minerals That Matter (and Why Winter Is Different)
Mineral needs shift in winter as forage quality changes, energy demands climb, and time on pasture decreases. A solid livestock mineral program supports immune function, reproduction, hoof integrity, and overall performance. In winter, producers often look for selenium and vitamin E support to bolster immunity—always match the product to your species and local conditions.
-
Cattle & horses: A consistent loose mineral paired with plain white salt tends to deliver steadier intake than hard blocks.
-
Goats: Use a goat specific mineral with adequate copper; offer salt separately so animals don’t overconsume minerals just for sodium.
-
Sheep: Choose a sheep safe, low copper mineral. Keep cattle/goat minerals out of sheep pens.
Placement: Put mineral where animals naturally pass—near feed and water—so they encounter it throughout the day and keep it dry.

Species Specific Tips
Cattle: In prolonged cold or late gestation, increase roughage and consider protein tubs or pellets to hold body condition. Provide windbreaks to reduce calorie drain, keep bedding dry, and check udders, feet, ears, and tail tips for frostbite risk.
Horses: Warm water helps prevent impaction of colic and keeps manure consistent. Use slow feed hay nets to extend forage time and reduce waste. Blanket only when warranted (age, coat, body condition, or wet/windy cold), fit and breathability matter more than the label.
Goats: Draft free shelter with deep bedding (straw or shavings) pays off. In extreme cold, add appropriate concentrates but maintain fiber for rumen health. Trim hooves regularly—damp, cold pens are tough on feet and can stress respiration.
Sheep: Keep roughage steady and avoid abrupt ration changes. For lambs, dry quickly and shelter well—chill risk accelerates in damp pens. Double check that mineral is sheep safe and store other minerals separately.
A Simple Winter Rhythm That Works
-
Daily: Confirm water is thawed and clean; check feed intake; do a quick health scan (eyes, nose, gait, manure, demeanor).
-
Weekly: Clean tanks/buckets; refresh mineral; rebed shelters; spot check hooves in muddy areas.
-
Monthly: Reevaluate body condition, adjust ration based on weather and hay test results, inspect cords/heaters, and restock essentials before the next cold snap.
Troubleshooting Fast
-
Low water intake? Warm the water, clean buckets, add a second bucket for choice, and verify heaters are functioning.
-
Hay refusals or weight slide? Swap to a cleaner, leafier lot; increase roughage on cold/windy days; add protein tubs or appropriate concentrates.
-
Mineral not getting touched? Move it closer to water or feed, switch to loose mineral if you’re using blocks, and keep it dry and fresh.
Final word: Winter livestock care isn’t about complicated formulas—it’s about consistent basics that work: heated stock tanks or deicers, clean, tested hay matched to the weather, and species-specific mineral with plain salt. Keep footing safe, bedding dry, and routines steady. Your animals will tell you you’re on track: steady intake, good manure, clean noses, and calm behavior are the daily green lights.
Always consult your veterinarian or local extension for herd specific nutrition and health plans, especially for late gestation, lactation, or ongoing health concerns.
