Abstract
British cattle in pipe and cable corrals in a hot environment consumed more feed, gained more weight, and in 3 out of 4 years improved energy utilization when given access to water cooled to 65F (18.3C) compared to 90F (32.2C). Level of roughage in the ration did not affect the response to cold water. In the 2 years in which water consumption was measured cattle. provided cold water drank significantly less than those given warm water. Brahman x British crossbred cattle under the same conditions performed similarly on cold or warm water. Warm water did not depress feed intake or energy utilization in crossbred cattle as it did with the British cattle.
