ABSTRACT:
The crate comprises two side members, a front member in the form of a trough assembly and a back member in the form of a rear gate for confining a sow within the crate in such a manner as to allow only limited movement of the sow. Each side member consists of a fixed retainer frame and a pivotable retainer frame pivoted on an upper rail of the fixed retainer frame so that the bottom rail of the pivotable retainer frame is movable outwardly to a limited extent when the sow applies her weight to it so as to enable the sow to lie down within the crate while being supported by the bottom rail. Pivotal movement of the two pivotable retainer frames is damped by a damper so that the sow is lowered to the ground in a controlled manner, and the two pivotable retainer frames are coupled together so that outward movement of one of the bottom rails will cause corresponding outward movement of the other bottom rail.
