Dairy farms are growing worldwide, and so are calf herds. Vital calves need to be fed 4-5 times a day, especially in the first few weeks of life, in order to achieve maximum milk yield later on. From a certain number of animals and feeding frequency in individual housing, the classic feeding methods with buckets are far too labor- and personnel-intensive. With the CalfRail and CalfRail DUO, feeding begins where manual methods come to an end. For farms of all sizes that want to grow staff-independent and are looking for maximum efficiency in calf feeding.
