An animal feeder has a hopper for receiving feed, the hopper having converging front panels with lower ends defining an elongate chute through which feed is directed. A shield is attached to each of the front panels and diverges from the front panel forming a cove that remains free of feed. A trough extends along the feeder and a water supply duct delivers water into the trough. An elongate shelf has a feed platform for receiving feed from the hopper. The shelf is positioned above the trough such that any feed falling, falls into the trough. The shelf has shelf retainers running longitudinally of the shelf above the feed platform, each shelf retainer directed between its respective shield and front panel. A height-adjusting mechanism adjusts the vertical position of the shelf relative the hopper and the trough. As the shelf moves upward, the shelf retainer moves into the cove.

A freeze-resistant watering device has a nipple or ball valve, a heat pipe, a sleeve in tight thermal contact with the nipple, a water-tight connection to a liquid containing container or supply pipe, and an outer shield enclosing an insulating space or insulation material. This device thermally couples a watering nipple or ball valve to a container or supply pipe via a thermal conduction path including bends so that the nipple or ball valve maintains at a temperature that is near the temperature of the liquid in the container or supply pipe. Further, the use of one or more freeze-resistant watering devices with a thermally insulated container in a watering unit with an insulated container or supply pipe provides drinking water to animals, and in particular, birds in sub-freezing and in hot weather.

A solar pet water dispenser, comprising a solar cell assembly, a water storage assembly, a water pumping assembly, a temperature control assembly, a living body sensor, a first control assembly and an induction switch, wherein the water storage assembly is provided with a water storage tank and a water holding lid which are hinged connected with the water storage tank; the water pumping assembly is provided with a first water inlet and a first water outlet, the first water inlet is connected with the water storage cavity, the first water outlet is connected with the water storage lid; the living body sensor is arranged on the water storage tank; at an input end of the first control assembly is connected the solar cell assembly, at an output end thereof is connected the water pumping assembly and the temperature control assembly, and at a control end thereof the living body sensor.

A circular grazing system for poultry and/or livestock. 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.

A water purifier includes a casing including a water intake port; and a filtering unit disposed inside the casing. The filtering unit includes a rotor including blades configured to guide fluid and rotatably disposed in a storage space in which raw water is accommodated inside the casing; a filter unit communicating with the storage space and configured to purify fluid supplied from the rotor and discharge the fluid toward the water intake port; and a stator disposed in a control space isolated from the storage space inside the casing and configured to transmit electromagnetic force to the rotor and rotate the rotor.

An animal watering device is provided that is automatically fillable for providing water to animals, such as horses or other livestock. Animal watering device includes a base, a trough positioned within the base for storing water, and a water filling assembly coupled with the trough to control a water level within the trough. A ring can be positioned about an upper surface of the trough to protect the upper surface of the trough. A disc can be positioned within the trough to cover a portion of water filling assembly positioned within the trough, while allowing water to flow through the disc.
