The invention relates to a device (1) for use in collection and removal of slurry or similar from a sty, a sty comprising such a device and to a method of installing a device at a sty, such as a pig sty, wherein the device comprises an one-piece body (2) having one or more funnels (3) wherein each funnel comprises at least one upper opening (3a) having an upper horizontal area enclosed by an upper edge (3a′) and a lower opening (3b) having a lower horizontal area enclosed by a lower edge (3b′), wherein the upper horizontal area is larger than the lower horizontal area, and the inside (3′) of the funnel is thus extending from the upper opening to the lower opening of the funnel, an encapsulation (4) enclosing the funnel from the lower edge of the funnel to the upper edge of the funnel, such that a ventilation space (5) is defined within the one-piece body between the encapsulation and the funnel.

A system for use in a poultry house includes a control server, a network gateway disposed in the poultry house and equipping with a wireless communication capability; a movable sensor module disposed in the poultry house, wherein the movable sensor module is movable within the poultry house for obtaining a plurality of environmental parameters associated with specific locations within the poultry house, and a sampling machine disposed in the poultry house for obtaining a sample of poultry waste on the ground of the poultry house. The movable sensor module transmits the environmental parameters to the network gateway, and the network gateway transmits the environmental parameters to the control server for processing the environmental parameters.

The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structures. The carbon dioxide is provided to one or more sealed greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby completely eliminating greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission and 24/7 electricity at better than market rates.

The invention relates to a method for reducing emission of ammonia from a livestock housing. The method comprises applying a composition comprising a compound that restrains ammonia volatilization onto freshly excreted manure by an animal in the livestock housing. Because the compound is deposited onto freshly excreted manure, ammonia volatilization is tackled at the source, rather than at a later moment, e.g. in a manure pit, when contact of faeces and urine, and therefore the conversion of urea to ammonia under the influence of urease has already led to volatilization of ammonia.

A ventilation control system for an animal facility. The ventilation control system has a movable ventilation control member mounted in an opening of the animal facility, the ventilation control member being movable relative the opening to control the amount of air that is able to pass through the opening. The ventilation control system also has a positioning strap attached to the ventilation control member, the strap having a strap thickness. A strap drive control apparatus is configured to control the positioning of the ventilation control member at a constant control member speed.

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 collection system for monitoring conditions of a rack of animal cages. An animal caging system including a plurality of animal cages removably connected to an exhaust. A collection media cartridge is slidably received within an opening in a collection media housing dock. The collection media housing dock is positioned between an exhaust plenum of the rack an exhaust air inlet unit. Collection media is removably received in the collection media cartridge. Exhaust air dust clings to the collection media as exhaust from the animal cages flows along the length of the collection media. The collection media cartridge can be removed from the collection media housing dock and the collection media can be removed for sampling the exhaust.

An improved poultry production method comprising providing dry hydrogen peroxide (DHP) to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

A ventilation system for a housing structure with a plurality of air vents including: vent control modules configured to control and actuate opening and closing of at least one air vent of the plurality of air vents; an electro-mechanical drive unit mechanically coupled to each of the plurality of vent control modules and providing mechanical power thereto, the drive unit including a motor and a drive shaft, the drive shaft being disposed parallel to the axis of the air vents; a control unit, in communication with the drive unit and the plurality of vent control modules, configured to control the drive unit and individually control each of the vent control modules; the vent control modules use the mechanical power of the drive unit to individually effect the opening and closing of each respective vent of the plurality of air vents.

A fan for use in agriculture which has a BLDC motor which allows for varying the speed of the fan to vary the airflow rate of the fan and vary the efficiency of the fan. A ventilation system for use in a livestock confinement building to maximize a rate of growth of the livestock. A process for maximizing the growth of livestock in a livestock confinement building by controlling the airflow in the livestock confinement building.
