Anyone tried producing Iberian pigs on eastern deciduous forest acorns?

I've read about the Spanish dehesa agrosilvopastoral system and was wondering if anyone has attempted a parallel version in the eastern U.S. oak-dominated woodlands? Has anyone produced Iberian pigs? I'm assuming they are a special breed with special considerations?

Check out the Curehouse in Louisville, KY they have a promo video on youtube. (http://www.youtube.com/watch?v=BV-GV9Ng2H0)
