Risks such as heat stress with loss of vitality, behavior and performance must be contained. There are special needs that need to be taken into account, especially in the calf and young cattle sector: limited thermoregulation behavior and the provision of small climate zones pose major challenges for proper air conditioning. For these reasons, hose ventilation systems have so far received little popularity in advice and practice. Adaptations and adequate adaptation of the systems to the conditions in the stable are to be examined in the course of this project and, if the test is positive, the area of ​​application will also be expanded to include the young cattle sector in the Alpine region in the future.
