An explanation of the anoxia principle
The Anoxia technique is developed as alternative for existing animal 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.
In the past 10 years, Wageningen University and University of Glasgow conducted several studies that proved that the technique could be applied successfully for culling poultry (Proof of Principle Anoxia Technique). This was the start of the development of several applications based on the Anoxia principle, using high expansion foam filled with >99% Nitrogen.
The technique has now been introduced in:
- Stunning and killing of sick and cripple killing piglets less than 5 kg
- 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)
- Stunning and killing of 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.)
- Stunning and killing of male pullets at the hatchery
- Stunning and killing of half-hatched chickens and embryos in partly-hatched eggs, before destruction
- Stunning and killing parent stock poultry
- Killing of animals that have been stunned (captive bolt – blow-on-the-head method, etc.) replacing killing by de-bleeding
- Culling of ex-layers
- Culling of poultry for disease control purposes
Last November 2016 the campaign started the launch of the commercialization of the Anoxia applications in Holland, Germany and Sweden, focusing on the areas where a solution is most needed: piglets (< 5kg) and poultry (> 3kg) on farms.
