UK Extension notes an electric heater can be added to almost any watering system. Choose a guarded, thermostatically controlled unit so animals cannot chew the cord.

How much they still drink
University of Kentucky's Master Grazer program puts a lactating 900 lb beef cow at about 11 gallons a day at 40 degrees, a wintering pregnant 1,000 lb cow at about 6 gallons, and mature goats at 1 to 3 gallons a day (UK Master Grazer). The goat extension network gives the same 1 to 3 gallon range for a 110 lb goat, closer to the low end in cold months, and notes that animals on dry hay drink more than animals on green forage (eXtension Goats). The same UK guide warns that "excessively cold water temperature will also decrease water intake."
Four ways to keep water open
- Tank deicers and drain-plug heaters. UK notes almost any system can take an electric heater, and some plug-in heaters install through a stock tank's drain plug. Use an outdoor-rated, grounded outlet and keep cords out of chewing reach.
- Heated buckets and heated poultry waterers. The simplest fix for a few goats, sheep or a backyard flock. Size to the herd so animals are not crowding one bucket.
- Heat tape on pipes and automatic waterers. UK lists plug-in heat tape for interior pipes and waterer bowls. Follow the manufacturer's instructions exactly; never wrap tape over itself.
- Geothermal or continuous-flow waterers. No electricity needed, but UK cautions they are "not ice-free" on the coldest days, and continuous flow needs an overflow line so you do not create a mud pit.
Buck note
eXtension recommends warm water for bucks in winter to encourage drinking and lower the risk of urinary calculi, especially on grain-heavy diets.
For trough sizing and when automatic waterers pay off, see our livestock water systems guide.
Daily winter check
-
Break and remove skim ice morning and evening.
-
Look for mud and ice around the waterer (foot rot and parasite risk, per eXtension).
-
Check every cord and outlet after storms.
