ABSTRACT:
An automatic sorting device for livestock comprises a chute through which animals are urged, and includes a first, open end, and a second end with two passageways therein. Each of the passageways leads to a separate livestock pen area. A pair of gates are operably connected with the device, and each selectively closes and opens one of the passageways. A weight sensitive mechanism is operably connected with the chute, whereby one of the gates is opened in response to an underweight animal walking through the chute, and the other gate is opened in response to a marketweight animal walking through the chute, thereby automatically inducing sorting the livestock by weight into the separate pens.
