ABSTRACT:
An apparatus and method for sorting animals includes a housing having a basket area and a measuring device. An entry gate is mounted to the housing and is moveable between open and closed positions. A sort gate is mounted to the housing and moveable between a first and a second position based on a measurement taken by the measuring device. A trainer gate is mounted to the housing and moveable through an operating position whereby the trainer gate contacts an animal in the basket area and urges the animal toward the sort gate. A programmable controller communicates with the measuring device, the entry gate, the sort gate and the trainer gate and controls actuation of the entry gate, the sort gate and the trainer gate.
