System and method for controlled atmosphere stunning of chickens or turkeys in a batch mode is provided. The disclosed method includes the steps of: loading one or more batches of chickens or turkeys in a stunning chamber and sealably enclosing the stunning chamber to isolate the atmosphere therein. Carbon dioxide is then introduced to the isolated atmosphere in a series of three, four, five or more phases to humanely stun and eventually kill the poultry. The carbon dioxide containing atmosphere is subsequently forcibly exhausted from the stunning chamber and the ranks of cages or modules containing the stunned poultry are advanced to a subsequent processing station such as a tipper or dumping station.

Système et procédé permettant d'étourdir dans une atmosphère contrôlée des poulets ou des dindes par lot. Le procédé consiste à amener au moins un lot de poulets ou de dindes dans une chambre d'étourdissement et à fermer celle-ci hermétiquement pour en isoler l'atmosphère. Puis, le procédé consiste à introduire du dioxyde de carbone dans l'atmosphère isolée en série de trois, quatre, cinq phases ou plus pour étourdir la volaille dans des conditions humaines et éventuellement la tuer, puis à évacuer l'atmosphère contenant du dioxyde de carbone de la chambre et à faire avancer les rangées de cages ou de modules contenant la volaille étourdie jusqu'à un autre poste de traitement, tel qu'un dispositif de basculement ou un poste de déchargement.
