A device for regulating the feeding of granular feed in a plurality of poultry mangers (M) through a distribution manifold tube (1) and a plurality of gravity feed vertical tubes (2), wherein the feed release aperture at the end of each vertical tube is regulated by a shutter sleeve (5) telescopically lowerable and liftable along the respective vertical tube (2) by acting on a rope system of suspension of the shutter sleeves (5) has, first means (12, 13, 14) and second means (7) for anchoring the two ends of a unified command rope (8) to the feed distribution tube (1), respectively on one side and the other side of said plurality of mangers (M), and rope supporting brackets (9) on the distribution tube (1) at least in correspondence of each vertical tube (2). A suspension rope (10) of each shutter sleeve (5) passes through an eyelet of the respective rope supporting bracket (9) through which the command rope (8) is also threaded and runs parallel thereto for a certain adjustable length and its end is fastened to the command rope (8). The first and second means (12, 13, 14, 7) for anchoring the opposite ends of said unified command rope (8) further comprises a spring (11) for tensioning the anchored rope (8) and a screw mechanism (12, 13, 14, 15) shifting the anchoring point of one end of the rope (8) for regulating the rate of release of granular feed onto the mangers.
