Abstract: A portable livestock feed dispenser is mounted on the bed of a flatbed truck, pickup, or other suitable vehicle. The dispenser comprises an elongate box or hopper with a dispenser end positioned adjacent one edge or end of the flatbed, for dispensing livestock feed to a feed site as desired. A lid extends over the entire top of the apparatus, with a hinge system allowing the lid to be positioned to one side of the device for filling the hopper. A lateral power auger extends the length of the structure, and receives feed from the upper hopper for dispensing from the dispenser outlet. The auger receives power from the electrical or other power supply of the vehicle upon which the dispenser is mounted, with auger operation being controllable remotely from the vehicle cab. A counter is driven by rotation of the auger, for measuring the amount of feed dispensed by the device. The counter may be mechanical, but is preferably electrically operated in order to provide a remote readout in the cab of the vehicle.
