Look at the pigs over on the east coast they lay in their own shit. As far as taste there are preservatives added to american pigs compared to those aboard scares me.
Dickie years ago i was at this one hog farm down in Maryland, it was the most disgusting place i have ever been to. Those hogs were rolling in their own shit in the most filthy looking pen i have ever seen. No bullshit, i don't think i ate pork for the next year. Just nasty, i've never seen such filthy animals in my life.
Those hogs in the picture you posted look like house pets compared to the hogs i saw at that hog farm in MD.
