A ventilation system is installed under the separated bottom floors partitioned by several partition walls (12) on a floor (11) of a livestock stall, such that forced air may be selectively supplied to the separated floor so as to help the sawdust fermentation. The ventilation system comprises an air blower (13) installed in the outside of the stall and a pipe line equipped with several shut-off valves (21). The pipes (14) having a lot of holes (16) are embedded on the separated bottom floor with a poromeric filler (15) such as pebbles. A perforated reinforcement plate (20) with a mesh (19) is mounted on the poromeric filler so as to allow the sawdust (18) to be heaped onto it.
