Unshaven animals often get too hot in the young cattle shed. Young stock, heifers and calves have a long and very dense winter coat. They don't need that coat in the young cattle shed. The winter coat makes them sweat very quickly.
The optimal comfort zone for a calf is at an ambient temperature of 15 ° C. If the calf is not dry, the calf will get cold and will burn more energy to keep itself warm.
In addition to vitality, this also costs growth and increases the risk of stress and respiratory diseases.
