Turkey hens were stunned by inducing anoxia with either argon (with approximately 2 per cent residual oxygen) or 30 per cent carbon dioxide in argon with 2 per cent residual oxygen, and the carcases were bled either immediately or five or 10 minutes after they had been stunned. A control group of turkeys was stunned electrically (250 mA for about four seconds) and had their necks cut immediately after stunning. The amount of blood lost was measured and expressed as a percentage of liveweight. The results showed that the necks of gas-stunned turkeys can be cut up to 10 minutes after they have been stunned without reducing the total blood loss significantly.
用火鸡做实验，分别用氩气（残余氧气约2%）或含2%残余氧气的30%二氧化碳与氩气混合气体使母火鸡缺氧致昏，致昏后立即放血，或者在致昏5分钟或10分钟后放血。另一组对照火鸡用电击致昏（250毫安，持续约4秒），致昏后立即割颈放血。测量放血量，并以活重的百分比表示。结果表明，气体致昏的火鸡在致昏后长达10分钟再割颈，总失血量不会显著减少。
