Humane animal slaughter has different varied meanings. In most cases, it is a matter of perspective. A vegetarian or PETA member will view any form of animal slaughter as inhumane while a subsistence farmer who only has a few blades and will hack an animal to death will view that as the most humane way of slaughtering the animal. In essence, human animal slaughter is about giving an animal as quick and as painless a death as possible. Humane animal slaughter seeks to ensure that the welfare of every animal is safeguarded up to the moment of their demise.
The primary factor inhumane animal slaughter is the pain. Before most farmers were forced by law to adhere to the humane slaughter of animals, no consideration was given to the suffering of the animal. All that mattered was the well-being of the consumers. It, however, became very apparent that animals suffer a lot before their death and it was not humane to subject them to that kind of torture. The above was primarily as a result of the use of rudimentary tools. It takes a lot of effort to behead a full grown car using a machete. It would only be slightly harder with a well-made Japanese sword. Humane animal slaughter seeks to rid animals of this pain so that the transition can involve as little suffering as possible.
Peace before death is something that all humans desire because we know what emotional stress and imbalance feel like to us. Before humane animal slaughter was made mandatory, most people did not consider it possible that animals can feel emotional distress. Animals can feel fear and mental discomfort as well. Therefore, inhumane methods of animal slaughter cause the animal a lot of distress before death. The above was clear by animals hesitating and running away from slaughter. Nowadays, an animal has to be unconscious before death. The above is done using a captive bolt stunner or gas where the animal is put to sleep so that it does not suffer before it meets its demise.
Humane animal slaughter is also about the humans too. It is not uncommon to have someone look away as a result of disgust or compassion at an animal being slaughtered. It seems a fundamental part of human nature not to want to see animals suffer or meet a painful end. The pain is heartfelt and almost as real as if one were experiencing it himself. Only someone who has repeatedly experienced the suffering of animals during slaughter can be unaffected by the act because he has been conditioned and is numb to their pain. Humane animal slaughter is about humans being at peace ensuring they gave the animal as peaceful a sendoff as they possibly. It is integral that people recognize the animal is what becomes food and continues to help them live.
Humane animal slaughter is both philosophical and systematic. It would be difficult to get a one size fits all approach to human slaughter. Whichever way one leans, the debate will continue into the foreseeable future.
