Automated livestock grazing system, comprising: - a set of exterior fences (1) fixed in the ground that enclose the grazing space, and a set of interior fences (2) equally fixed that sectorize said space. the fences (1, 2, 3, 4) will be formed by a minimum number of two posts (10) and a minimum of one crossbar (11). They may also have a metal mesh attached to them. The outer fences (1) and the inner fences (2) may also be formed by a series of posts (10) joined with wire, lacking crossbars (11). - a set of rotating fences (3) arranged as road sorters or as regulators for the passage of livestock, interposed between the outer fences (1) or the inner fences (2), or in other positions within the enclosure bounded by the outer fences (1). The movement of the rotating fences (3) may be provided by motors (12) whose axis (13) will be rigidly coupled to a pole (10) of the rotating fence (3) or by linear actuators (14), which will be joined together through a ball joint (15) to a projecting crossbar (16), the post being closest to said joint provided with the ability to turn on its own axis by means of the joint with joints (17) fixed to the ground. They will be able to count on sensors and limit switches (18) on the own rotating fences (3) or other fences (1, 2) to stop their movement. Both the motors (12) and the linear actuators (14) will be fixed in the ground, directly or with auxiliary means such as bars or poles. - a set of displacement fences (4) that will have two symmetrical rail assemblies (19) and advancement device (20). The rails (19) will be anchored to the ground. Each of the advancement devices (20), will be formed by a base (21) with a motor support (22) on which an advance motor (23) is attached. The motor shaft (24) thereof passes through a hole in the base (21) and is attached to a roller (26) that allows movement by rolling with the rail (19). A non-motor shaft (25) will be housed in another hole in the base (21) and will be attached to another roller
