Livestock feed wagon (1), comprising a frame (2), a feed container (3) which is fitted on the frame, in particular provided with feed- mixing means (4,5,8), a gripper construction (10) having a movable arm construction (11) and a gripper (13) fitted thereon for grabbing an amount of animal feed (15) from a pile of animal feed (16), furthermore comprising weighing means (25), wherein the weighing means are arranged and configured to weigh a grabbed amount of animal feed by determining a change in the weight of at least the feed container and the gripper construction with the grabbed amount of animal feed. As a result thereof, it is possible to determine both the total loaded weight in the feed container and the weight of a grabbed chunk of animal feed using the same weighing means, so that the chunk, if it is either too heavy or too light, can be returned prior being unloaded, if desired.
