When building finishing barns the focus has generally been on reducing capital costs, but ways to enhance performance should also be taken into consideration. If barns could be built to improve feed conversion in finishing pigs, the additional capital investment would be paid off by increased profit per pig. Also, currently more pig spaces are needed in Ontario to produce enough pigs to keep packers at capacity and profitable. The cost of pig space could be reduced if identical barns were built, or at least limit barns to a couple of floor plans. Also, galvanized steel roofs could potentially be used with the right insulation to lower cost per pig space. The current Canadian barn style can be changed to consider long-term operation costs, or could model after cheaper American barns.
