Experiments were conducted in finishing pig houses located in the Veneto Region (Po Valley,
Northern Italy). The pig houses, which have fully slatted floor with slurry channels, are cleaned
by means of a vacuum system. On the bottom of the channels, pipe outlets are placed every 10
m2 and connected to a sewerage system. Slurry is discharged by opening a valve in the main
slurry pipe, without any mechanical pump; a slight vacuum develops and allows the slurry to
