Automatic calf feeding systems are known to save labor and increase calf growth due to the higher milk intake. At the same time, modern machines generate a wealth of data that can be used for assessment of health status and weaning success. Together with new sensors like activity neckbands with search-LED or cloud-connected thermometers, the calf health insight can even be broadened and partly run automatically. This breakout session will demonstrate how to access data and come to fact-based decisions on future usage of the animal.
