Today, however, about 90% of US breeding sows – the mothers of the pigs that are raised and killed for pork, bacon, and ham – spend most of their lives locked in cages that measure about two feet by seven feet (0.6 meters by 2.2 meters).
V USA však dnes zhruba 90% chovných prasnic – matek prasat chovaných a zabíjených na vepřové maso, slaninu a šunku – tráví většinu života uzamčeno v klecích o rozměrech asi 0,6 krát 2,2 metry.
