TYPES OF INSTRUMENTS

•  Ray’s electrical stunner
  • It consists of a pair of tongs provided with a sponge and attached to a step-down transformer.
  • The operator grips the animal behind the ears with the electrodes and allows the current to pass into the animal by operating the switch in the handle of the tongs.
  • The electrodes are furnished with a sponge dipped in salt solution to enable the current to pass more easily through hair and hide.
• Modified electrical stunner
  • Apart from the above said features in the Ray’s electrical stunner, the tips of the electrodes are modified to form metal cups with serrated edges and the cups are fitted by absorbent pad.
