Historically and even in current times, killing without shedding blood or without cutting thrhough the neck and beheading the animal is considered improper, taboo or defiling it in many cultures. What you said about commercial slaughterhouses is probably true, I've heard they wring chicken necks to break them as well. The problem with that is , it feels like you are slaughtering after killing as opposed to slaughtering as part of killing. I don't really know the specifics more than what people have told me but it is hugely frowned upon to not spill blood right away. May have something to do with how ritual animal sacrifice in many cultures required the animal's blood to be spilled into something and the blood of an already dead animal is not ok? Keep in mind, modern animal killing has to be "humane" as in be acceptable to people who never get close enough to see that stuff. Similar to capital punishment I suppose. The concept of an honorable/respectful killing is strange to modern western minds who only care about minimizing pain as a measure of cruelty.
