    • The present invention concerns a procedure and equipment for the treatment, such as anaesthetisation or killing, of poultry by using gas. The gas comprises oxygen and carbon dioxide, among other components. During the treatment, the oxygen concentration is kept constant at a normal level (18 - 22 vol.%). This is important as it allows the poultry to breathe normally while the natural body functions can be maintained in their normal state until anaesthetisation takes place. The concentration of carbon dioxide is increased either continuously or discontinuously. With the present invention it is possible to anaesthetise poultry before slaughter in a way which produces low levels of stress and discomfort in the poultry while, at the same time, the quality of the meat is better than with the use of traditional methods. In the equipment the poultry are exposed to the gas in a chamber (1), that may comprises a belt conveyer (5) and further be separated into three treatment zones (2, 3 and 4).
    • 本发明涉及通过使用气体处理家禽的方法和设备,例如麻醉或杀死家禽。 气体包括氧和二氧化碳等组分。 在处理过程中,氧浓度保持恒定在正常水平(18-22vol。%)。 这是重要的,因为它允许家禽正常呼吸,而天然的身体功能可以保持在正常状态,直到麻醉发生。 二氧化碳浓度连续或不连续地增加。 利用本发明,可以在屠宰之前以在家禽中产生低水平的压力和不适的方式麻醉家禽,同时肉的质量比使用传统方法更好。 在设备中,家禽暴露于腔室(1)中的气体,其可以包括带式输送机(5),并进一步分成三个处理区域(2,3和4)。
