The main purpose of this research work was to analyse the most efficient spatial distribution of pig production units in the state of Goiás. The model developed required a mixed integer programming structure. The factors considered in the model were: the grain transportation cost (corn and soybeans) from the source to the production unit, the cost of transporting the animals from the production unit to slaughterhouses and the carcass transportation cost from the slaughterhouse to retailers. The consumption market was spatialy defined as comprising the state of Goiás, the Distrito Federal and the counties of São Paulo, Rio de Janeiro and Belo Horizonte. Moreover, it was determined the supplies of corn and soybeans for each microregion in the state of Goiás and the national per capita pork consumption. Three scenarios, showing different per capita consumption levels, were considered. One of these is the current per capita consumption level and the two other were determined according to sector perspectives.
