To take a 50 pound feeder pig to a market hog size (220/240lb) it will require 10 bushel of corn and 150 of protein supplement. This can be accomplished in 115 days. Figure your input costs on this and add in your fees for feeding, watering and risk along with some profit. Let the buyers pay the processors and transporting. Save some money by not buying the processed feed at $9 per bag.
