Combi-Tunnel ventilation--The all-weather system

摘要

Animals of highly fdmproved breeds combined with a high stocking density require a climate of precise adjustment. The Combi-Tunnel ventilation is developed by SKOV; it insures the animals the most optimum climate under climatic conditions of great fluctuations of temperature. Great demands are made on the climate system in the livestock house to ensure an exact adjustment of temperature, air humidity and air velocity in order to create optimum conditions. If the air humidity rises, the animals sensea higher temperature even though the temperature is actually unchanged. Likewise, a low humidity can make the animals feel a lower temperature even though it has not been lowered. The opposite applies as regards air velocity. If it is increased, the animals feel a lower temperature even though the temperature is unchanged. There is only one correct temperature - if it is not sustained an optimal productivity cannot be maintained.
