Abstract: An apparatus is described for dispensing precise quantities of particulate medication to livestock, in particular sows during gestation. The apparatus includes a medication hopper having a lower discharge opening; a mechanically or electrically actuated measuring valve including a chamber having a volume corresponding to the volume of the desired medication dosage. The chamber is movable between a first position in which the chamber inlet is aligned with the hopper discharge opening and a second position for discharging medication from the chamber. A discharge conduit extends downwardly from the chamber discharge opening, and has outlet end positionable adjacent the area where the medication is to be dispensed. In a preferred embodiment, the apparatus includes wheels and a counter.
