Summary:
At birth, and for the first few weeks of life, calves are unable to properly regulate their own body temperature and are vulnerable to low environmental temperatures. At low temperatures, calves have to expend energy to maintain their body temperature, which can have a negative impact on performance and health. The simplest way to keep calves warmer is to provide them with deep dry bedding. However, consideration of housing design and materials, or using external heat sources such as heat lamps or calf jackets can also have a role to play.
