Cutaneous Evaporation in Different Body Regions of Black and White Holstein Cows in a Tropical Environment.

Thermal comfort of animals in tropical regions depends largely on their ability to dissipate excess body heat by evaporative cooling, being skin surface evaporation the main avenue of heat dissipation in cattle in those environments (Maia et al., 2005a). Major portion of the moisture available for cutaneous evaporation is contributed by sweat glands, which are not homogeneously distributed over the bod
