The livestock feeder includes a relatively shallow, open top tank having a substantially solid bottom and generally vertical side and end walls, a rack located inside the tank for receiving different types of feed and having a plurality of horizontally spaced frame members which extend upwardly from the tank bottom with their lower ends spaced inwardly from the tank walls to define feeding troughs therebetween, and an outer framework having a plurality of frame members which are arranged to discourage the withdrawal of loose feed from the feeder. In a preferred embodiment the frame members are horizontally spaced in parallel relationship and extend diagonally from the upper extremity of the tank walls. Adjacent pairs of the diagonally extending outer frame members define a vertically angled opening through which individual livestock can project its head, while standing on the ground outside any one of the four sides of the feeder, and eat feed held in the rack and/or the feeding troughs. The angled opening between the diagonally extending outer frame members discourages livestock from dragging feed from the feeder. The central portion of the tank bottom preferably is raised and includes a pair of oppositely inclined walls which cause the feed to slide from inside the inner rack into the feeding troughs. When loose feed, such as chopped green feed or ground feed, is to be dispensed, panels are removably mounted on the inner frame members to define a bin for receiving the loose feed.
