I recently found a provider at my local farmers market that supplies GF beef and pasture raised pigs. I'm confident that the beef is GF, but I heard the farmer explaining that he feeds the pigs a mixture of corn, soybeans and molasses to supplement their diet.

Is this common for pasture raised pigs or is there a higher standard that isn't fed supplemented that I should shoot for? I realize that pasture raised pigs certainly will be healthier than their lot raised counterparts as they are allowed to wallow and root around, etc etc. Is this considered primal enough or just marginally better?
