We have a saying here in Spain: from swine, even the gait.
Yes, they only have two hinds each, but front legs are sold too (paletilla), papada (jowl), morro (snout), manitas (hoof), lengua (tongue), oreja (ears), various embutidos (cold meat) made traditionally stuffing meat and fat inside pork intestines (like chorizo, salchichón...)
And of course everything else that's traditionally edible anywhere in the world (loin, ribs, etc.) EDIT: except muslim countries of course.
