A livestock and like feeder of the type in which a horizontal trough drops feed material into the tops of a plurality of vertical drop tubes, each tube being provided with a metering device for intercepting and subsequently dropping a predetermined amount of feed to a lower trough or the floor, etc., for animal consumption. The improvement resides in improved metering elements, each comprising a partial cylindrical member in each drop tube, dimensions to fit the drop tube in intersection fashion on a horizontal axis and configured with an upwardly facing pocket sized to receive the predetermined amount of feed. The member is invertible by rotation on the horizontal axis to dump the amount of feed while presenting a part-cylindrical portion of its surface upwardly to temporarily prevent additional dispensing until the member is turned back to receive a further and like amount of feed.
