Revolutionary new technique

After 10 years of research & development a revolutionary new stunning technique is introduced. Based on the principles of animal welfare as described in the Terrestrial Animal Health Code of the International Standards of OiE: The Anoxia technique – stunning and killing animals by placing them under atmospheric conditions in an environment without oxygen. The solution is not only simple and safe and cost-efficient; it is also not physically demanding to the farmer and his employees.


Animal welfare

The principle guarantees that the animal(s) are placed in an environment with pure nitrogen, once the high expansion foam, filled with 100% nitrogen, replaces the atmospheric air inside the container. From that moment on, the animal inhales pure nitrogen, an atmospheric gas that all living species are used to and that can be inhaled without any physical reactions because atmospheric air contains 78% nitrogen that is inhaled by every breath.


Simple technique

The newly developed and patented technique is simple. All it needs is a soap dispenser connected to a water tap; a soap concentration; a bottle of pure nitrogen including a regulator; a standard waste 240/340/370 liter wheelie-bin container; and the Anoxia lit that closes and seals of the container. Inside the container, a high expansion foam generator is placed, connected to the water/soap and nitrogen through flexible tubes, connected to the inside of the lid. A chiffon is added to the lid, in order to allow atmospheric air to escape the container when it is filled with foam.

Standard Operating Procedure

According to the Standard Operating Procedure, the water/soap and the nitrogen tubes are connected to the electrical valves on outside of the Anoxia lid. Then the animal(s) are placed in the bin, next to the foam generator. The lid is closed and the foam production is started.


Stunned within 30 seconds

After 30 seconds, the container is filled completely with foam. At the moment that the foam is placed in the container via the chiffon, the foam production is stopped and the chiffon is sealed off. Throughout the foam production process the animals remain calm. The high concentration of nitrogen replaces the oxygen in the blood and via the longs; nitrogen is transported to the organs instead of oxygen. The first organ that reacts is the brain that immediately shuts of consciousness.

Body reactions

The contractions of the muscles start after the brain is no longer able to control the movements of the muscles and is not a sign of stress, like with traditional gas stunning methods, where oxygen is gradually replaced with gasses like CO2 or Argon.
Therefore the Anoxia technique is the revolutionary alternative for existing stunning methods that are based on the use of CO2, electrocution, neck dislocation, captive-bolt, as well as killing methods like de-bleeding and maceration.


Anoxia applications

Several applications based on the Anoxia principle are now introduced for:
1. Stunning and sick and cripple killing piglets less than 5 kg
2. Stunning and killing of sick or cripple poultry (especially poultry > 3kg) who need to be killed on the farm by the staff for welfare purposes (avoiding unnecessary stress or pain)
3. Stunning and killing poultry that arrives on the slaughterhouse but that are unfit to be slaughtered (due to injuries occurred during transportation – providing signs of possible illness etc.)
4. Stunning and killing of male pullets at the hatchery
5. Stunning and killing of half-hatched chickens and embryos in partly-hatched eggs, before destruction
6. Stunning and killing parent stock poultry
7. Killing of animals that has been stunned (captive bolt – blow-on-the-head method, etc.) replacing killing by de-bleeding
8. Culling of ex-layers
9. Culling of poultry for disease control purposes


Sales started December 2016

The first application that’s introduced on market in Germany, Holland, Sweden and Denmark can be applied for Stunning and killing piglets less than 5 kg; – poultry > 3kg (turkey and parent stock); and embryos in partly-hatched eggs.
