Humane methods of killing (theory)
When you need to kill -
(1) collecting of blood and tissues,
(2) culling of breeding stock,
(3) disposal at the end of an experiment,
(4) circumstances where animals are experiencing pain and distress which cannot be alleviated.
International council for laboratory animal science regulations
(2) When performing euthanasia, the intention should be to make the animal’s death as distress-free and painless as possible. Therefore, the method likely to cause the least distress and pain to the animal should be selected, consistent with the nature of the experimental protocol.
(3) Euthanasia should result in rapid loss of consciousness, followed by respiratory and cardiac arrest and ultimate loss of all brain function.
(1) Whenever an animal’s life is to be taken, the animal must be treated with the highest degree of respect.
(4) Euthanasia should aim to minimize any pain and distress experienced by the animal prior to loss of consciousness. When appropriate, restraint should be used in such a manner that pain and distress associated with the entire process are minimized.
(5) Methods used for euthanasia must be appropriate for the species, age and health status of the animal.
(6) Death must be verified following euthanasia and prior to disposal of the animal..
(7) Personnel responsible for carrying out the euthanasia must be trained to carry it out in the most effective and humane manner; recognize signs of pain and distress in relevant species; and recognize and confirm unconsciousness, and subsequently death, in relevant species.
(8) Human psychological responses to euthanasia should be taken into consideration when selecting the method of euthanasia, but should not take precedence over animal welfare considerations
(9) Animal care committees are responsible for approval of the method of euthanasia for any study involving the use of animals. This includes euthanasia as part of the experimental protocol, as well as euthanasia for animals found to be experiencing unrelievable pain and distress or approaching previously agreed endpoints.
(10) A veterinarian experienced with the species in question should be consulted when selecting the method of euthanasia, particularly when little research has been done on euthanasia of that species.
euthanasia as “…the act of humanely killing animals by methods that induce rapid unconsciousness and death without pain or distress”.
Direct depression of neurons necessary for life function
Hypoxia
Physical disruption of brain activit
methods of killing
Overdose of Anaesthetic - all animals
Carbon Dioxide - birds and rodents
Anaesthetic Gas + Carbon Dioxide
Cervical Dislocation (anesthetic before hand for rodents and rabbits)
Concussion
Recognised Slaughterhall/Slaughter person Methods - farm animals
6 ways to assure they are dead
Onset of Rigor Mortis
Mechanical Disruption; When there is no response to painful stimuli
Exsanguination; Denies a blood supply to the brain, usually by severing large blood vessels in thorax or abdomen.
cardio-respiratory failure. - Dislocation of the neck
Destruction of the brain; Means permanent loss of brain function - Occasional movement or irregular gasping may occur due to brain stem reflexes.
Permanent cessation of the circulation; No detectable pulse or heartbeat; animal does not respond to painful stimuli; section heart and great vessels.
disposal via maceration or incineration
