Elevated environmental temperature, solar radiation, and relative humidity leads to hyperthermia or heat stress. Heat stress is defined as any combination of environmental conditions that will cause the effective temperature of the environment to be higher than the temperature range of the animal’s thermal neutral zone. When rectal temperature is greater than 39.2 °C and breaths exceed 60/min, cows are on the verge of experiencing significant heat stress; this is the point at which the cow will heat up exponentially if exposed to further increases in temperature and humidity.Elevated environmental temperature, solar radiation, and relative humidity leads to hyperthermia or heat stress.
