Temperature
Calves need to maintain a constant body temperature around 38,8⁰C. When the temperature is below 15⁰C, the calf uses extra energy to stay warm. This has a negative effect on growth and resistance. In addition, calves are very sensitive to the effects of heat stress, which occurs at temperatures of 28⁰C or higher. Heat stress causes the calf to expend energy to dissipate excess heat from its body, resulting in less weight gain, reduced health, and growth goals corresponding to its age.
