Proper infrared heat lamp use for efficient livestock production (1993)

Abstract

Electric heat lamps provide a versatile, inexpensive heat source for today's livestock production farming practices. Heat rays from infrared lamps pass through the air without heating it, as does energy from the sun. When these rays strike an animal, heat energy is absorbed. Using this radiant heat principle, lamps mounted at the proper height establish "comfort" zones where young animals can move about and seek the degree of warmth desired.
