Methods of slaughter
Some of the methods are:
Lethal injection: Emergency killing by lethal injection is typically carried out by a veterinary surgeon. The animal will be injected intravenously with a lethal dose of anesthetic drugs following, in some cases, initial injection of a sedative. The animal will rapidly lose consciousness and die. When an animal is killed by lethal injection there may be restrictions on how the carcass can be disposed of. The carcass cannot be used for human or animal consumption if it has been killed by lethal injection.
Free-bullet firearms: The operator of any firearm must be competent in order to protect the welfare of the animal. It is very important that the correct ammunition is used, otherwise the animal might not be killed immediately and/or the operator could be injured. The use of firearms in enclosed spaces, or when animals are on hard surfaces, could result in ricochet of free bullets and is to be avoided for health and safety reasons. There is no need to bleed or pith an animal following effective use of firearms. Humane killer, shot guns, .22 rifles can be used. Once shot, the animal should collapse and may bleed from the bullet entry point, its nose and its mouth. After shooting (typically starting about a minute later) the animal may demonstrate some involuntary movement of the limbs but this is normal and does not necessarily indicate consciousness.
Captive-bolt stunning followed by bleeding or pithing: Captive-bolt stunning followed by bleeding or pithing can be used for emergency killing of animals where a free-bullet is impractical for safety reasons. Certification and licensing may be necessary for the use of this method. A captive-bolt stunner fires a retractable bolt against the animal’s head and in many cases into the animal’s brain, rendering it immediately unconscious. The animal will collapse, but there may be some involuntary movement of the limbs. There is likely to be some bleeding from the hole in the skull made by the bolt and from the nose of the animal.
External trauma followed by bleeding: Infant lambs, kids and piglets can be humanely killed by delivering a heavy blow to the head. This must only be used if no other method is immediately available.
