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.

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 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 method and apparatus for providing welding-type power includes receiving an input that may be either a single or a three phase input voltage. Three power modules, each having a single phase boost power circuit, and an output circuit process the input power. A weld output circuit receives and combines the outputs of the three power modules. An input power distribution module connects the three power modules such that each receives a unique single phase power signal. A controller controls the three power modules and the input power distribution module.

The present disclosure relates to providing a continuous, autonomous monitoring system of environmental parameters, harmful gases and greenhouse gases in animal stables. A network of internet-of-things (IoT) sensors can be installed in a stable that produce alarm signals in case of danger or if predetermined threshold values are exceeded. The sensors work continuously and communicate through different wireless protocols with a dedicated cloud platform. The cloud platform stores the values received by the various sensor units and transmitted via dedicated monitoring devices and elaborates them applying data analysis processes.

The ecosystem for methane conversion and emissions reduction disclosed herein presents a low-cost solution to the global methane accumulation problem. Ruminants generate gases as part of their digestive process, including methane, and the negative effects of methane in our atmosphere are well known. Many attempts are underway to use diet modifiers to lessen the amount of methane created and therefore minimize the effect. The presented invention takes a different approach. A methane converter is used in conjunction with a closed system to first transform the methane into the less damaging CO.sub.2 and then to use the CO.sub.2 for feeding algae growth. Methane at concentration levels in the enclosed habitat are maintained low to minimize the possibility of explosion, and the conversion from methane to CO.sub.2 is triggered by heating the low concentration methane with a heated surface or small flame.

Kinetic energy devices, such as fans or blowers, are selected or controlled to attain a determined optimal overall average airflow for a volume within a livestock building to satisfy one or more predetermined livestock production objectives.

An animal cage includes a removable, suspended interior floor provided with a plurality of perforations formed therein. The floor creates a plenum inside the cage allowing air to flow laminarly through the perforations and liquids or liquid waste to substantially fall through the perforations in the raised floor.

A method and 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. Collection media is removably mounted in an exhaust plenum of the rack using a holder. Exhaust air dust clings to the collection media as exhaust from the animal cages flows along the length of the collection media. A door to the exhaust plenum can be opened and the collection media can be removed from the holder.
