A one houndred year old Swedish barn is turned into the most modern of calf barns. The automatic cleaning evacuates the manure from the barn within two hours and gives a good air quality in the barn - actually the main reason for chosing this equipment, and a prerequisite to keep on using the old building. In addition the automatic cleaning saves working hours and provides a basis for really good calf health. This specific barn is a reception barn for dairy calves that are bought from other surrounding farms.
