Abstract
A ventilated age and rack system having an enclosed ventilated rack and a plurality of barrier cages on the shelves of the rack includes a liquid manifold for transporting a liquid to a plurality of predetermined positions along the shelves. A drinking valve is positioned within the cage to allow an animal to consume liquid supplied by the liquid manifold without leaving the cage. A coupling couples the liquid manifold to the drinking valve so that liquid may flow from the liquid manifold to within the cage when the cage is placed in the rack at the predetermined positions. An air plenum transports positive pressure air to the plurality of predetermined positions. A recessed grommet having holes therein is positioned in the bottom of each cage and allows air to pass from the air plenum to within the cage.
