The system for managing bird populations includes a drone; a disruptor comprising an extension arm having a proximal end and a distal end, the proximal end being operatively coupled with the drone, and the distal end comprising a tool portion, where the tool portion comprises a piercing element constructed for engagement with one or more eggs in a nest; and a remote control system. The remote control system may comprise one or more remote control units and a monitor.

The system can be used to manage bird populations by flying the drone above a bird's nest; positioning the drone above the bird's nest; and descending the drone to disrupt eggs in the bird's nest with the disruptor.

An apparatus for stunning an animal with an exhaust gas mixture includes a stunning chamber located at a processing site to contain therein as many an animal selected to be stunned; and a combustion chamber located at the processing site for combusting a mixture to provide therefrom an exhaust gas mixture which includes carbon dioxide for stunning the animal in the stunning chamber. A related method and exhaust gas mixture are also provided.

A method, system, and apparatus for humanely dispatching wounded game in the field comprises a shank with a connecting end, a curved region, and a pointed end connected to a grip formed at the connecting end of the shank, and a finger loop. The grip can further comprise a series or flattened portions configured to engage the gaps in a choke tube in order to remove the choke tube.

A method is provided for reducing animal reactions when exposed to a pre-stunning relaxation gas and/or stunning gas during a pre-stunning and/or stunning process. The method includes: exposing at least one animal to a pre-stunning relaxation gas and/or stunning gas for an exposure period; exposing the at least one animal to at least one smell additive at least during a part of said exposure period, in particular during an initial part of said exposure period.

A method for monitoring gas stunning of birds, where groups of birds are conveyed into and out of a stunning zone (1), and where the concentration of the stunning gas in the stunning zone is measured and adjusted for optimal stunning. The gas concentration is measured at a plurality of measuring positions in the stunning zone and a visual inspection of the birds is performed at two or more of the measuring positions using a visual inspection unit (76), such as a camera, which is moved into the stunning zone together with the group of birds. The groups of birds are advantageously kept in crates (3). The visual inspection unit may be part of a monitoring unit (71) further including a gas sensor (75), said monitoring unit being used for simultaneous measuring of the concentration of the stunning gas and inspection the birds at two or more monitoring positions.

In accordance with example embodiments, a system may include a supply unit, a first transfer unit, a second transfer unit, and a gas chamber. In example embodiments, the supply unit may include a plurality of compartments and each compartment may have a moving device configured to move contents of the compartment from a first end of the compartment to a second end of the compartment. In example embodiments the first transfer unit may include a second moving device. In example embodiments, the second transfer unit may include a third moving device. In example embodiments the first transfer unit may be configured to receive contents from each compartment of the supply unit and move the contents to the second transfer unit, and the third moving device may be configured to move the contents to the gas chamber.

Method and apparatus for processing slaughtered poultry that is conveyed in a slaughter line of a slaughter house, in order to establish at the start of said slaughter line whether the poultry was alive or dead on arrival at the slaughter house. Such can include the detection of a body parameter of the slaughtered poultry when the poultry is suspended by the legs in the slaughter line after stunning said poultry, and wherein an absorption spectrum of blood of the slaughtered poultry is determined.

An apparatus for assessing compliance with animal welfare on an animal for slaughter. The apparatus has an image capture unit with a capture region in which a section of a surface of the animal is optically captured and in which pixels are captured. The capture unit provides pixel data in a transmittable manner. The apparatus has an evaluation unit connected to the capture unit to capture the pixel data. A normative model of the animal is stored in the evaluation unit and represents a formation of animal-related features conforming to animal welfare. The evaluation unit relates the pixel data to the model and determines a deviation of the pixel data from the model and provides the deviation as a deviation of the animal from the model in a form that can be output. A method for assessing compliance with animal welfare is carried out on the apparatus.
