Abstract
EGYPTIAN cattle, buffaloes and high-grade shorthorns were used for studying the effect of age, lactation and fattening on heat tolerance coefficients. The method developed by Rhoad1 was used in estimating the heat tolerance, and the test was carried out twice during July 1952. The atmospheric temperature during test days ranged between 91° and 98.6° F., and relative humidity between 42 and 68 per cent. The average body temperatures of animals during March 1950 were taken as normal body temperature2.
