In an experimental study on stunning of 460 turkeys in a CO2 enriched atmosphere (60-70% CO2 in air), as a more animal protecting and more economic alternative to conventional electrical stunning, the following results are obtained: all animals show respiratory arrest within 100 seconds. After being dipped in a CO2 enriched atmosphere for a few seconds the turkeys show head shaking and forced respiration which has to be considered as a strain the animals are conscious of. The meat hygienic results after CO2 stunning are much better than after electrical stunning.
在一项关于在富含二氧化碳的环境（空气中二氧化碳含量为60 - 70%）中使460只火鸡昏迷的实验研究中，作为一种比传统电击昏迷更具动物保护意义且更经济的替代方法，获得了以下结果：所有动物在100秒内出现呼吸停止。火鸡在富含二氧化碳的环境中浸泡几秒后会出现摇头和强迫呼吸，这必须被视为动物能意识到的一种应激。二氧化碳昏迷后的肉品卫生结果比电击昏迷后的要好得多。
