The invention discloses a cattle shed, comprising a cattle bedding, a feeding channel, a fixed roof, a movable roof, a feeding trough, a peripheral rail fence, and a rail fence gate, wherein the cattle bedding is provided with no dividers and needs no hardening and daily manure cleaning, which is merged with playground and enclosed. The feeding channel is hardened and higher than the cattle bedding, the fixed roof and the movable roof cover the cattle bedding and the feeding trough, the peripheral rail fence and the rail fence gate surround the cattle bedding and the feeding trough, and the fixed roof and the movable roof are arranged in a slope mode, and the movable roof can be opened to allow sunlight to enter and exchange air to form convection. The cattle shed of the present invention can reduce the construction cost, open the movable roof, effectively utilize the sunlight and the air convection, ensure a complete rain-sewage separation, and realize zero discharge of manure and sewage.

A ventilation and temperature regulation structure for an animal house, comprising a house body and a temperature regulation device with a culture layer, the house body comprising a temperature equalization device and an exhaust gas extraction device, the temperature equalization device includes a temperature equalization passage passing through the culture layer, several ventilation holes are disposed on the side wall of the temperature equalization passage; and an outlet end of the temperature regulation device is connected with the temperature equalization passage. Such technical solution is to provide a temperature regulation structure for an animal house having good ventilation, waste reduction and good effect of temperature regulation.

A lighting assembly includes a light guide having opposite first and second major surfaces and at least one edge surface extending between the first and second major surfaces, a solid-state light source arranged to emit light into the edge surface of the light guide, and a plurality of integrated optical elements associated with the first major surface to redirect the light emitted by the solid-state light source. The lighting assembly may further include an air circulation device and a heat transfer system configured to transfer heat generated by the solid-state lighting source to a flow of air generated by the air circulation device. The solid-state light source may include light-emitting diodes, laser diodes, and/or organic light emitting diodes configured to produce multiple colors. Also provided is a habitat including the lighting assembly, and related methods.

A pet shelter includes a floor, a roof, and a sidewall. The sidewall is made of a transparent material and joins the floor and the roof together. The sidewall includes a first portion joined to a second portion by a first bend, the second portion joined to a third portion by a second bend, the third portion joined to a fourth portion by a third bend, and the fourth portion joined to a fifth portion by a fourth bend defining an internal spiraled compartment An entrance to the internal spiraled compartment is defined in between the first portion and the fifth portion of the sidewall.

A structure for sheltering and cooling livestock may include a concrete floored barn having an improved evaporative cooling system. The cooling system may include a misting stack having air inlets, a mixing chamber, and three cooling zones wherein the cooling zones correspond to three different temperature ranges. Each of the cooling zones may include a plurality of nozzles which produce a mist. As air passes through the mixing chamber, the mist may evaporate and cool the air. The cooling system may further include a plurality of large exhaust fans located at an end of the barn distal from the misting stack. The fans may draw the cool air through the barn, over and around the livestock, and out of the barn.

One aspect of the present disclosure can include a multilayer static housing system for preventing the ingress of microorganisms therein. The housing system can include a static outer housing unit and at least one static inner housing unit nested completely inside of the outer housing unit. Airflow through the housing system can be driven passively by the chimney effect.

A shipping container for livestock having a plurality of walls, a container roof and a container floor enclosing an interior storage space. The front wall may include a container door and one or more of the sidewalls may be mounted with one or more column support plates that support web support plates. A floating partition, end wing, loft and feed troughs may be mounted with the web support plates. Additionally, the floating partition may be tilted inward to efficiently divide space and provide access to the loft. A catwalk may also be mounted with the floating partition.

An environment-friendly piggery comprises at least one circular or polyhedral piggery building. Each polyhedron has five sides or more, and a ventilation shaft is provided in the middle of each floor of each piggery building; each floor tilts from high to low towards the ventilation shaft from the outer edge; the top of each piggery building is provided with a exhaust gas collecting and treatment device communicating with the ventilation shaft; and the bottom of the buildings are provided with pig excreta collecting devices corresponding to the opening of the ventilation shaft. The piggery occupies a small area, has strong wind and snow resistant functions, and is sturdy and durable. The culturing process is pollution-free, and piglets, pigs, and sows can be accommodated appropriately.

A cage for housing laboratory animals, said cage comprising a tray and a cover which can be removed and switched between a first closing position, in which it is positioned on said tray thus stopping the access to the internal space delimited by said tray, and a second opening position, in which said internal space may be accessed.

A side of an animal enclosure including a plurality of interconnected horizontal and vertical wires, where the plurality of horizontal wires includes a top wire and a bottom wire, and the plurality of vertical wires includes a first end wire and a second end wire. A plurality of hooked ends are formed at the ends of either the plurality of horizontal wires or the plurality of vertical wires. The top wire, the bottom wire, the first end wire, and the second end wire define an outer periphery of the first member, and the plurality of hooked ends extend beyond the outer periphery defined by the top wire, the bottom wire, the first end wire, and the second end wire. The top wire, bottom wire, first end wire and second end wire do not form a hooked end at any of their respective ends.
