A livestock feeder device comprises an inner frame defined by an upper circular rail and a lower circular rail resting against the ground together with a number of uprights for receiving and confining a cylindrical bale. An outer frame around the inner frame is defined by a lower panel and an upper area having inclined spaced bars arranged so that the animal can present its head through the bars but is halted at the shoulder. The spacing between the inner and outer frames is such that the animal can reach the bale and is encouraged by the frame to eat with its head remaining between the inner and outer frames so as to deposit any waste in that area for subsequent eating. This avoids the trampling of any waste and thus reduces losses.
