Amidst all my studying I came across this

Most people believe, in a vague way, that slaughterhouses are unpleasant, but that animals raised for food are otherwise treated humanely. In fact, farm animals live in abhorrent conditions before being taken off to slaughter. Veal calves, for example, spend twenty-four hours per day in pens so small that they cannot turn around, lie down comfortably, or even twist their heads around to get rid of parasites. The producers put their heads in tiny pens to save money and to keep their meat tender. The cows clearly miss their mothers, and like human infants, they want something to suck, so they try in vain to suck the sides of their wooden stalls. The calves are also fed a diet deficient in iron and roughage, in order to keep their meat pale and tasty. Their craving for iron becomes so strong that they will lick at their own urine, if they're allowed to turn around-which normally they would never do. Without roughage, the calves cannot form a cud to chew. For this reason, they cannot be given straw bedding, since they would eat it, in an attempt to consume roughage. So, for these animals, the slaughterhouse is not an unpleasant end to an otherwise contented existence.
