 The Humane Slaughter Association states that the transport of pigs to slaughter and all the other procedures and circumstances leading up to the actual act of stunning and killing the pig are, in modern times, often carefully arranged in order to avoid excessive suffering of animals, which both has a humane rationale as well as helping provide for a higher quality of meat.Animal rights groups have recorded images of pigs being transported to slaughter in cramped and unhygienic conditions.They state that the transportation does cause suffering, which has economic rationale.
