Abstract:

The present invention relates to a duct and ventilation system for livestock production buildings. The building comprises a plurality of containment rooms for livestock, a pit beneath the room, an attic above the rooms, a ventilation duct for each room and a ventilation house coupled to the pit. The containment rooms have slatted floors. The attic includes a vent. Each ventilation duct includes a manually actuable air flow control valve. The ventilation house includes an exhaust fan and is adapted to draw air through the vent and through the attic to one of the ventilation ducts and into one of the rooms through the slatted floor and out via the ventilation house. The building may include a manifold area adjacent the rooms and in fluid communication with the attic. Ventilation ducts comprise a laminar polymer sheet having a generally rectangular shape and forming a corner generally parallel to first and second side edges, a second laminar and planar polymer sheet having a first edge and a second edge, and a plurality of brackets. The first edge of the second sheet attaches to the first sheet such that the second sheet is substantially parallel to the corner.
