Body Surface Evaporation Rates at Low and High Temperatures in Murrah Buffalo

Abstract

Evaporation rates of water from the skin surfaces were measured by capsule technique on three body locations of five Murrah buffalo heifers. After being accustomed to hot, dry (summer), hot, humid (monsoon) and cool (winter) ambient conditions, the heifers were moved to a psychrometric control room maintained at either 18.5 C dry bulb temperature, 13.0 C wet bulb temperature or 40.5 C dry bulb temperature, 35.0 C wet bulb temperature. Evaporation rates and skin and rectal temperatures were recorded between the fourth and sixth hour of exposure in the control room. The conditions of exposure prior to the tests had a significant (P < .01) with evaporation rates (avg –.60). © 1968, American Dairy Science Association. All rights reserved.
