A multi-storey animal house includes a multi-storey animal house body with multiple breeding storeys. The breeding storeys include a first breeding storey, a second breeding storey, a third breeding storey, a fourth breeding storey, a first cultivating storey, and a second cultivating storey which are sequentially arranged from top to bottom.

An air odor removal system with sewage or septic plumbing attachment removes odors from a toilet assembly by having a conduit fluidly coupling ambient environment around the toilet assembly to the inside of a toilet tank and another conduit fluidly coupling the inside of the toilet tank with an air mover, e.g., vacuum, wherein the air mover will remove air within the toilet tank, which typically includes a negative odor, and transfer said air and odor, through another conduit, to a one-way valve of a sewage plumbing conduit, typically referred to as an air admittance valve for discharge.

A cage assembly can have at least one enclosure. Each enclosure can have a floor defining a floor area having a major dimension and a cover having a bottom surface. A spacing between the bottom surface of the cover and the floor can define a cage height. At least one sidewall can extend between the floor and the cover. A ratio of the cage height to the major dimension of the floor area of each enclosure of the at least one enclosure can be at least 0.70.

A base carrying a left-side panel and a right-side panel. A top panel is disposed on and extends between said side panels, wherein said base, said side panels and top panel define a pet receiving area. A blower unit disposed at a rear side of said pet receiving area drawing air in a direction from a front side to said rear side of the housing across the pet receiving area. An airflow control covering disposed on at least one of said left-side panel and said right-side panel providing a reduced airflow entering said pet receiving area through the side panel relative to a front side of the housing, wherein a negative air pressure is established within the housing while providing a primary airflow direction from said front side to said rear side of the housing to container pet hair, dander and debris within said housing.

A filter holding frame that may be used agricultural environments. The filter holding frame may include a plurality of interconnecting members with an upstream hemmed edge and downstream opposing flanges. The opposing flanges of the members may define a sealing face configured for a plurality of air filters. The members of the outer periphery of the filter holding frame may include the mounting surface and the sealing face.

An enclosed litter box is provided that includes a housing sized and shaped for an animal and litter tray. The apparatus includes a self-closing door that impedes airflow between the interior and exterior of the housing and can be utilized by an animal as an entrance and exit to the housing. The apparatus further includes a recirculation ventilation system that includes a fan to draw air from the interior of the housing through a filter and then circulate the filtered air back into the interior of the housing. This filter is configured to remove odor from the air.

A livestock shed for keeping livestock animals includes a shed building for keeping the livestock animals, having a floor which is at least partially permeable to excretory products from the livestock animals, a liquid-tight manure cellar for collecting excretory products which is situated at least partly under the floor, and an air scrubber connected to the manure cellar and configured to at least partly clean polluted manure cellar air. The air scrubber is provided directly above the manure cellar.

The invention relates to a device for use in large-scale industrial insect farming. More in particular, the invention relates to a live insects transport device for transporting live insects from a first location to a predetermined second location, the live insects transport device comprising a fluid guiding unit, a fluid discharge member and a feeder arrangement, wherein the live insects transport device is configured to receive live insects such as freshly hatched neonate larvae, for example of black soldier fly, wherein the live insects are taken up in a laminar flow of fluid and while in said fluid are transported to a predetermined location in the live insects transport device. Furthermore, the invention relates to the use of the device in industrial insect farming, such as large-scale farming of black soldier flies, and the invention relates to a method of dosing live insects, wherein preferably live insects are doses which are essentially of the same age, such as freshly hatched neonate larvae.

A base carrying a left-side panel and a right-side panel. A top panel is disposed on and extends between said side panels, wherein said base, said side panels and top panel define a pet receiving area. A blower unit disposed at a rear side of said pet receiving area drawing air in a direction from a front side to said rear side of the housing across the pet receiving area. An airflow control covering disposed on at least one of said left-side panel and said right-side panel providing a reduced airflow entering said pet receiving area through the side panel relative to a front side of the housing, wherein a negative air pressure is established within the housing while providing a primary airflow direction from said front side to said rear side of the housing to container pet hair, dander and debris within said housing.

Disclosed are systems, methods, and non-transitory computer-readable media for automated behavioral and physiological testing of untethered testing animals. An automated behavioral testing system communicates with electronic devices attached to testing animals to provide automated physiological measurements and perturbations. The electronic devices are wirelessly charged to eliminate the need to remove the electronic devices during the course of the study. The automated behavioral testing system includes a filtering chamber positioned between a housing chamber and a behavioral testing chamber. The filtering chamber provides a passageway between the housing chamber and the behavioral testing chamber used to manage access to the behavioral testing chamber. For example, a gate component implemented between the filtering chamber and the behavioral testing chamber can be configured into either a closed configuration to restrict access between the filtering chamber and the behavioral testing chamber, or an open configuration to permit between the filtering chamber and the behavioral testing chamber.
