Abstract: A livestock production building includes an automatically controllable ventilation system which provides ventilation to livestock containment rooms. Incoming air may be heated, cooled and/or filtered, and is mixed and tempered before being delivered to livestock rooms. Substantially all exhaust air is filtered to mitigate environmental impact.

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.
