Abstract: Disclosed is a novel, portable, animal feeding station which provides livestock, at virtually any desired location, waste-free access to fibrous feed material in quantities heretofore unobtainable with a portable unit. Compacted fibrous feed is charged into a rectangular-shaped, variable volume hopper formed by a pair of upstanding stationary, spaced-apart, opposing end walls and a pair of movably suspended mesh-covered side panels. The side panels are movably suspended on sloping tracks mounted interior the end walls such that the panels are positioned by gravity against the confined feed mass. Feeding livestock are able to grasp the fibrous feed through the mesh according to their need, and in doing so forcibly urge the panel, along the sloping tracks, against the remaining feed mass.
