Comparison of different air supply and cooling systems in pig fattening houses

摘要

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 fur Schweinezucht (LSI 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.
