Abstract: A feeding trough for flying animals, particularly turkeys, capable of adjusting the level of the feed, of the type in which the feeding troughs are arranged in series along distribution lines of the feed in sheds, is described. The feeding trough is of high stability and at the same time permits to adjust the level of the feed with a simple and rapid maneuver which may be carried out in a centralized position of the shed. The feeding trough comprises a suspended plate (2), supported by arms (3) which are connected directly to the horizontal tubular conduit (5) used for the transportation of the feed. The feeding trough also comprises an element for the distribution of the feed in the plate which comprises an element (11) for the regulation of the level of the feed. The latter is actuated by means of cables from a centralized position of the shed.
