Speaking of "chemicals", they are ever so much MORE tasty when killed DRT and they never knew what hit them, than the alternative of poking a hole in them and then chasing them down to either dispatch or find dead somewhere else. The "primordial soup" of fight or flight chemicals in the blood and muscle tissue does not marinate the meat to any palatable liking of which I am aware. It can be masked to a degree, but is wholly better to dispatch a hog DRT - lights out - from the get-go without the chemicals and kill them without their faintest knowledge of what hit them. Oh yeah. Pork - it's what's for dinner!
