The reactions of turkeys to the presence of either 90 per cent argon in air (anoxia), 72 per cent carbon dioxide in air or a mixture of 30 per cent carbon dioxide and 60 per cent argon in air with 3 per cent residual oxygen were tested. The majority of the turkeys did not avoid a feeding chamber containing either argon or the mixture of carbon dioxide and argon, but 50 per cent of the turkeys avoided a feeding chamber containing 72 per cent carbon dioxide in air. It is concluded that from the point of view of welfare, either 90 per cent argon in air or a mixture of 30 per cent carbon dioxide and 60 per cent argon in air, would be preferable to a high concentration of carbon dioxide for stunning/killing turkeys.
测试了火鸡对空气中含有90%氩气（缺氧）、72%二氧化碳或30%二氧化碳与60%氩气的混合物以及3%残余氧气的反应。大多数火鸡没有避开含有氩气或二氧化碳与氩气混合物的喂食室，但50%的火鸡避开了含有72%二氧化碳的喂食室。得出的结论是，从福利角度来看，对于使火鸡昏迷/致死，空气中90%的氩气或30%二氧化碳与60%氩气的混合物比高浓度二氧化碳更可取。
