- Winterizing livestock watering systems is important to prevent freezing - Insulating water tanks is one way to prevent freezing, options include storing the tank in an insulated structure or covering the tank with insulation materials - Positioning water troughs close together creates "heat islands" that can prevent freezing and thaw frozen water - Additional heat can be supplied using electric water de-icers or heated buckets - De-icers can be placed at the base of the waterer or submerged in the water - Propane powered heaters are an alternative for areas with limited access to electricity - Heated buckets are a better solution for providing water to fewer animals - Water circulators can be used to keep water moving and prevent freezing - Automatic cattle waterers automatically fill with water from a pressurized line to prevent freezing
