The objective of this study is to determine the optimum economically location of new slaughter and processing plants of poultry and pork in Brazil, considering the minimization of transportation cost and acquisition of corn and soy bran, and the transportation cost of meat. The theory of localization was used, as theoretical approach, reletead to the weberiana theory of the industrial localization, used, with larger intensity. Network capacited model is used as analytic tool. The main result was the indication of Cândido Mota, SP, for the set the processing plant, due, mainly, a short distance among that municipal district and the corn production cluster and its proximity with important meat consuming areas, and with the main ports. The results indicated: for two plants, Cristalina, GO, and Mafra, SC; for the three plants, the two cities previously mentioned, with the inclusion of Cândido Mota, SP, and for four plants, it is insert Lucas do Rio Verde, MT. It was observed that the minimum medium cost of attendance of meat demand, considering the brazilian internal consumption and the exports, was resultant of to opening of four plants that cost decrease was due to reduction in the distance traveled by the until the consuming markets.
