Incapacitation of a mammalian subject results from the application of a pulsed, low-power electric waveform. The waveform is applied to the subject at a frequency and over a time period sufficient to induce involuntary muscular contraction. Additionally, the contraction causes limited lactic acid production and is non- or minimally-injurious to the subject's tissues. A device utilizing such a waveform is designed to control or otherwise subdue an individual.

The present disclosure generally relates to a method for humanely stunning and slaughtering poultry, and more particularly to a method for decreasing the spastic wing activity of poultry during slaughter. In particular, the birds are placed into a sealed chamber and the pressure in the chamber is reduced at a continuous rate to a target decompression pressure. The low atmospheric pressure slaughter is more humane than traditional slaughter techniques and results in less spastic wing activity.

A method of stunning an animal for slaughter includes the steps of providing the animal for slaughter; conveying the animal using conveying means; while conveying, causing a first current pulse having a maximum duration of 10 seconds to flow through the head and/or neck region of the animal to stun the animal; and, while conveying, causing a second current pulse to flow through the body of the animal to cause a cardiac arrest. The first and second current pulses may be applied successively or may be overlapping or partly overlapping.
