An Outdoor Pig Production System (SISCAL), at the Experimental Station Agronomic Institute of Paraná State was used with the objective to determine the establishment and production costs of this system in the Southwestern region of Paraná. The SISCAL area was dimensioned to a 14 sows and one boar herd, which was divided in paddocks to separate the animals per physiological stage (reproduction, gestation and nursery). The establishment cost was based on the labor, material used for the system installation and the manufacturing of some equipment, as well as the feed plant and storage construction costs and equipments for the ration production. The total establishment observed cost of the SISCAL, excluding capital value of land, was of US$ 6862.80 or US$ 490.20 per housed sow, in July 1997. The feed plant and storage construction costs as well as the equipments were the items that increased the establishment cost most. The production cost per kg of weaned pig was US$ 0.617 in June 1999. In this period it was possible to get an 18.81% of net income per kg of produced pig.
