| 摘要 |
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).
