The meat can be different depending on the way they die, If they die moving, the meat will actually taste different because of the movement in the meat when the animal died. For example game meat. If you ate a slaughterhouse chicken and then the exact same type of chicken, but killed while it was running away, you will find the meat will change in the way it is. Most people like non game meat so they prefer the meat from animals who were killed without the animals knowing it was coming. Plus, they try their best to keep the animals from feeling pain, knocking the pigs out before slitting their necks, only rare failures do they have pigs wake up. Would you rather die with your neck slit while you are sleeping, or awake. One way you wouldnt feel it, but the other way you will.
