Unfortunately some religious rules require inflicting extreme and unnecessary suffering on animals in the way they are killed. Interestingly some abattoirs have created loopholes to these religious laws (to comply with the food production laws, but maintain religious certification) by having the machines that stun and kill the animals in the normal humane way "blessed" and prayers said.

I assume you're not speaking about judaism right now — because the point of kosher slaughter is exactly in avoiding unnecessary suffering and rendering the animal unconscious instantly.
