The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis. ## Claims ### Claim 1 A circular grazing system comprising: a center pivot structure installed at a field, wherein the center pivot structure has a center pivot axis and the field includes one or both of a poultry and livestock grazing field; and an enclosure for containing one or both of poultry and livestock that extends generally radially from the center pivot structure to a circumference of the field, the enclosure comprising two side barriers including a first side barrier and a second side barrier extending generally radially from the center pivot structure to the circumference of the field, and a third barrier coupled to the first side barrier and the second side barrier that connects the two side barriers to form the enclosure, wherein the enclosure is rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis; a motor; and one or more processors configured by machine readable instructions to actuate the motor causing the enclosure to rotate at least partially around the center pivot axis, wherein actuation of the motor is programmatic such that rotation of the enclosure around the center pivot axis is intitiated via the machine readable instructions. ### Claim 2 (depends on 1) The circular grazing system of claim 1, wherein the enclosure is floorless. ### Claim 3 (depends on 1) The circular grazing system of claim 1, wherein the enclosure includes a chassis with wheels that facilitates movement of the enclosure around the center pivot axis. ### Claim 4 (depends on 1) The circular grazing system of claim 1, wherein there is a clearance between (i) a bottom of at least a portion of at least one of the two side barriers and (ii) the field such that at least a portion of the enclosure may pass over one or both of deceased livestock and poultry lying in the field. ### Claim 5 (depends on 4) The circular grazing system of claim 4, further comprising one or more flaps coupled to the bottom of the at least one of the two side barriers. ### Claim 6 (depends on 1) The circular grazing system of claim 1, wherein a lower portion of at least one of the two side barriers is resiliently flexible so that live animals are maintained in the enclosure, but the lower portion passes over dead animals. ### Claim 7 (depends on 1) The circular grazing system of claim 1, further comprising one or both of a pressurized perforated airline pipe and one or more sound devices coupled to the enclosure and oriented in the direction of the movement of the enclosure. ### Claim 8 (depends on 7) The circular grazing system of claim 7, wherein one or both of: the pressurized perforated airline pipe releases compressed air from airline perforations in the pressurized perforated airline pipe, and the one or more sound devices are automated to induce one or both of poultry and livestock movement responsive to the enclosure rotating around the center pivot axis. ### Claim 9 (depends on 1) The circular grazing system of claim 1, further comprising a feeding system. ### Claim 10 (depends on 9) The circular grazing system of claim 9, wherein the feeding system is automated to distribute one or both of food and milk within the enclosure. ### Claim 11 (depends on 1) The circular grazing system of claim 1, further comprising a water supply. ### Claim 12 (depends on 11) The circular grazing system of claim 11, wherein the water supply is automated to distribute water within the enclosure. ### Claim 13 (depends on 1) The circular grazing system of claim 1, further comprising a mobile milking station system including one or more milking stations that rotate around the field and include one or more conduits that transfer milk radially to one or more central collection vats. ### Claim 14 (depends on 1) The circular grazing system of claim 1, further comprising an irrigation system, wherein the irrigation system includes an arm extending radially from the center pivot structure that is rotably coupled to the center pivot structure, wherein the irrigation system moves one or both of clockwise and counterclockwise around the center pivot axis at a different rate than the enclosure. ### Claim 15 (depends on 1) The circular grazing system of claim 1, wherein the machine readable instructions actuate the motor causing the enclosure to rotate around the center pivot axis in accordance with one or both of a schedule and rotation rate. ### Claim 16 (depends on 15) The circular grazing system of claim 15, wherein the one or both of the schedule and rotation rate indicate one or more of: when the enclosure will rotate around the center pivot axis, one or more durations the enclosure will rotate around the center pivot axis, and a speed at which the enclosure will rotate around the center pivot axis. ### Claim 17 (depends on 1) The circular grazing system of claim 1, further comprising one or both of a fourth barrier extending generally radially from the center pivot structure to the circumference of the field and a fifth barrier extending generally radially from the center pivot structure to the circumference of the field, wherein the fourth barrier or the fifth barrier and the first side barrier form a second enclosure for containing one or more of cows, sheep, and goats, and wherein the fourth barrier and the second side barrier form a third enclosure for containing pigs. ### Claim 18 (depends on 17) The circular grazing system of claim 17, wherein the enclosure contains poultry and wherein the enclosure, the second enclosure, and the third enclosure have an order configuration including: (i) the second enclosure for containing one or more of cows, sheep, and goats in front of the enclosure for containing poultry, (ii) the enclosure for containing poultry in front of the third enclosure for containing pigs, and (iii) the third enclosure for containing pigs behind the enclosure for containing poultry, wherein the front corresponds to the direction in which the enclosure rotates around the center pivot axis. ### Claim 19 (depends on 1) The circular grazing system of claim 1, further comprising one of both of a fourth barrier extending generally radially from the center pivot structure to the circumference of the field and a fifth barrier extending generally radially from the center pivot structure to the circumference of the field, wherein the fourth barrier and the first side barrier of the enclosure or the fifth barrier and the first side barrier form a second enclosure for containing one or more of cows, sheep, and goats; and wherein the fourth barrier and the second side barrier of the enclosure form a third enclosure for containing pigs. ### Claim 20 (depends on 1) The circular grazing system of claim 1, wherein a proximal end of the enclosure proximal to the center pivot structure has a narrower width than a distal end of the enclosure distal to the center pivot structure. ### Claim 21 (depends on 1) The circular grazing system of claim 1, wherein the enclosure is pie-shaped.
