I've read elsewhere on this forum that pigs can be raised sustainably at a density of about 10 per acre. If a sow produces 20 feeders per year in a farrow-to-finish operation, the finished hogs have a butcher weight of 160 pounds, and the hanging, pasture-fed, organically raised hogs are sold for $2.00 per pound, then an income of around $6000/yr/sow can be had if all the food and labor is provided by the farm. So, if the density figure is correct, then one sow with two acres can provide an income of $6000. If a direct scale can be used, then a 20 acre farm could provide an income of $60,000 annually.
