what are the cost involved in raising pigs the nyman way?e biggest cost -- and this goes for conventional farming as well -- is probably need. you're looking at reading them -- feeding them corn. they are eating alfalfa and other vegetation that is there that they have planted in the field. you are also looking at the capital cost -- building the barn, the facilities, providing the corn stalks that nyman requires the pig to sleep on, and they also have certain specifications for the depth of the betting that the pigs at the room allowed for each paid. really, when you look at the differences in cost and production, it comes down to what nyman's ceo was talking about -- the pigs, when they grow this way grow more slowly so you are just not getting as many pigs in the same amount of time. when you look at an operation like brenneman, which is obviously a much larger individual -- operation and whose individual pigs are more productive, the economics, from their perspective, that they have to just produce more pigs. mark: how much of the farmer
