A feeding trough which is accessible to livestock animals is disclosed, and is defined at the bottom and laterally by a bottom wall and side walls, respectively, wherein one of the side walls demarcates the trough interior for an access side from which the animals take up feed from the trough interior. The side wall on the access side has an upper side wall edge over which an animal's head must reach at least partly so that the animal can take up feed from the trough interior and a trough frame to which the feeding trough is fixed. An adjustment mechanism is provided for adjusting the height of the side wall edge on the access side relative to the trough frame.
