<p>A crush for livestock comprises side frame members (11) between which an animal to be held may be driven, and neck-retaining means (12-14), the neck retaining means being movable between an open position and a closed neck-retaining position, in which the neck-retaining means may be pre-set in an intermediate partially-closed position and includes an operating mechanism whereby the said means are automatically caused to assume the closed position as the animal enters the crush. Preferably the neck-retaining means (12-14), which may be gates which have profiled edges to define a neck-receiving aperture therebetween, are arranged to close in a progressive or step-wise manner to increase the restraining force on a restless animal.</p> |
