The primary reason for carrying out this technique is to obtain a large volume of blood which has not been affected by anaesthetic drugs or carbon dioxide. A large volume of blood can be collected from the trunk if necessary.
Suitable for all strains of rat, this technique should only be used in exceptional circumstances. The ASPA limits its use to rodents of body weight 1 kg or less. Concusssion of the brain is acheived by striking the cranium. The rat must be determined as dead before decapitation can take place (see Section 1(4) of the amended ASPA).
Concussion of the brain is a Schedule 1 method of euthanasia and should only be carried out by people competent in this method for the species and size of the animal. Training for stunning and decapitation should be undertaken on dead animals.
