A University of Alberta study where newborn calves were chilled to a body temperature of 86°F and then warmed to normal body temperature with either: 1) a combination of a heat lamp, blanket and housing at 72°F; or 2) immersing the calf in 100°F water in a bathtub, greatly favored the tub method. The calves warmed up twice as fast in the warm water and expended half as much metabolic energy as those under the heat lamp.

     Researchers remind producers not to forget to hold the calf’s head out of the water as it is warming up and remember to dry it off before returning it to its’ dam. Also, they suggest saving some of the afterbirth or fluids to rub on the calf to help the dam claim it after being warmed up (JAS 1988).
