The young calf up to one month old is highly susceptible to cold stress. The calf jacket provides an effective and simple way to keep the calf warm whenever the temperature drops below 10⁰C. This prevents weight loss (the calf otherwise must use energy from food to keep warm) and protects the sick calf that is particularly vulnerable. The jackets are very well made and practical, they can be machine washed so infectious diseases are not spread from one animal to another. I have seen some farms where all the calves are wearing them and others where the farmers have bought just a few to use on small or sick calves. They work very well.
