Livestock take in less water during cold weather, but it's still the most important nutritional component. Keep water heaters turned on to avoid freeze-ups. Confinement-raised livestock are at risk when the weather causes power failures. Windows can be opened, but cold stress soon takes its toll on animals and the building's water system. Keep adequate backup generators in good condition for emergencies.
Nutritional needs are another concern.
Animals raised outdoors burn more energy just keeping warm during extreme low temperatures. Producers should increase feed about one percent for each chill factor degree below 20 degrees. Remember that chill factor is influenced by wind, humidity and precipitation in addition to temperature drops. Finally, newborn calves, pigs, lambs and foals need special attention during freezing temperatures. Calves and foals just need shed protection for about 24 hours to give them a good start.
