For the sake of efficiency and lower costs, Premium Standard Farms of Princeton, Missouri has turned pig production into a standardised product-focused process. Slaughterhouses have done this for a hundred years - but after the animal was dead. Doing it while the animal is a relatively recent innovation. Here how it works. Impregnated female sows wait for 40 days in metal stalls so small that they cannot turn around. After an ultrasound test, they wait 67 days in a similar stall until they give birth. Two weeks after delivering 10 to 11 piglets, the sows are moved back to breeding rooms for another cycle. After 3 years, the sow is slaughtered. Animal-welfare advocates say such confinement drives pigs crazy. Premium Standard replies that its hogs are in fact comfortable, arguing that only 1% die before Premium Standard wants them to and that their system helps reduce the cost of pork products.
