The invention provides a feed displacement device for picking up, displacing and dispensing material, in particular livestock feed, including a rail system and a trolley with a gripping device, which trolley is movable over the rail system, and is configured to pick up and dispense the material, wherein the rail system includes a fixed rail part and a displaceable rail part which is connectable to the latter, wherein the trolley is movable directly over the fixed and displaceable rail parts, and in such a manner that the trolley can cover a surface area for picking up the material from various positions. The trolley is easily positionable over an area where material, such as feed, is to be picked up. As a result thereof, no robot arm or the like has to swing out sideways and thus no unnecessarily large forces act thereon. In addition, the device overall is compact since the trolley is in effect displaceable in two directions by combining the displaceability along the displaceable rail part and the displaceability of the displaceable rail part itself.
