ADVANTAGES OF ELECTRICAL STUNNING

• The bleeding is excellent after electrical stunning.This is due to:
• The continued function of the heart and maintenance of the arterial blood pressure (at a higher level than when animals are stunned by captive-bolt type instrument)
• The nature of the muscular contraction, which expels the maximum amount of blood from the skeletal, muscles in a manner similar to the squeezing of a sponge. 
•  The violent and incoordinated muscular contractions are noticeably absent after electrical stunning and during the act of sticking.
• The efficacy of electrical anaesthesia is dependent on the total quantity of electrical energy supplied, expressed in watt-seconds (watt seconds = voltage x amperage x time) rather than the individual factors of voltage, amperage or time.
