Continuous exposure of cattle to summer heat in the absence of shade results in significant hyperthermia and impairs growth and general health. Reliable predictors of heat strain are needed to identify this condition. A 12-day study was conducted dur

[First paragraphs]: Heat exchanges with the environment are crucial processes for maintaining homeothermy by humans and other animals. These exchanges involve heat production, conservation, and dissipation, and are dependent on both biological and ph
