Abstract
A method for stunning animals and a respective stunning system is disclosed. Animals are lowered in a cradle into a pit filled with anoxic stunning gas. The cradle is provided with a heat sink, preferably comprising solid carbon dioxide, for cooling the stunning gas in the pit resulting in a density increase of the stunning gas in the pit. This reduces demixing of the stunning gas and rising of components such as nitrogen (N2) usually having a lower density than the air surrounding the stunning system.
