WebMice and humans prefer to live within their thermal neutral or comfort zone, respectively, at which they expend the least amount of energy to defend their core temperature. The normal housing temperature (T a =20-22°C) is within the thermal comfort zone of clothed humans, but below the thermoneutral zone (T a =30°C) of mice. WebApr 1, 2024 · A calf is below its “thermal neutral zone” when the environmental temperature drops below 60 degrees Fahrenheit, meaning she is now spending extra energy to stay warm rather than using those calories for growth. (Leadley) Newborn calves have only 3-4% body fat, which is not much to spare when trying to stay warm in the colder weather. johnson floor tiles india johnson floor wax paste
