There is need for research regarding the optimization of air supply and of air cooling systems of livestock houses for fattening pigs. A decision support project for the German Ministry of Agriculture has been established to investigate such technologies on a research farm and under practical conditions. Since January 2011, on the research farm Landesanstalt fr Schweinezucht (LSZ Boxberg) measurements on three air supply and cooling systems have been carried out: Underfloor air inlet and supply, cooling pad and high pressure evaporative indoor air cooling. The present results show differences concerning the parameters: temperature, differential pressure, air velocity and energy consumption .
