German dairy farmers have implemented a new rule that requires calves to be at least 28 days old before leaving the farm, resultinging in heavier and stronger calves. These changes have had positive impacts on the health and development of veal calves, with fewer digestive problems and lower mortality rates. However, the higher body weight of these calves may increase the need for medication. The article also highlights the need for adapting feeding strategies and housing for these older calves, and suggests that measuring the hemoglobin level in their blood and providing veal calf milk could be beneficial.
