A method of performing a procedure on an animal involving stunning and/or killing said animal

摘要

A method of performing a procedure on an animal involving i) gas-based stunning, and/or ii) gas-based killing, using a foam. The foam contains a gas having a gas composition suitable for performing the procedure, such as pure nitrogen. The procedure is performed using a container (100) and the method comprises the steps of - introducing the foam in the container (100) and - performing the procedure. To reduce any problem caused by the susceptibility of foam to break up, the animal is introduced in the container (100) and subsequently the foam is used to expel at least 90% of the air in the container (100) from the container (100).
