The New Zealand Veterinary Association (NZVA) opposes the use of electroimmobilisation equipment because controlled scientific studies have shown it may cause aversive behaviour and unnecessary pain and distress and because no significant analgesic effect has been demonstrated.
The effectiveness in achieving immobilisation has been demonstrated. The behavioural effects on the animal are hard to judge as this is inevitably modified to a degree by the electroimmobilisation itself.
The question remains unanswered as to whether the animal is humanely immobilised and anaesthetised, or whether it can still feel pain but not respond. In fact could the act of electroimmobilisation itself be considered cruel?
Significantly, the procedure has been demonstrated to be aversive,.and anaesthetic properties have not been established.
The use of electroimmobilisation is illegal in Great Britain and Europe.
