Adaptation of Bovine Sweat Glands to a Hot Environment.

MURRAY, D. M.

THE increase in human sweating following acclimatization to heat is well known1. Bianca2 found that, with cattle, repeated exposure to heat (37° C) in a psychrometric laboratory resulted in a progressive reduction in body temperature, respiratory rate and heart rate. However, there is little evidence of any causal adjustment of sweat gland activity under these conditions. Experiments by McLean3 and Banerjee et al.4 suggest that the sweating rates of cattle under artificial heating are directly related to the prevailing temperatures animals have been previously exposed to.
