| Summary: | Most small farmers in Brazil have in pig farming activities an alternative to obtaining the food of high nutritional value and profitability. The objective of this work was to implement and develop a system of sustainable extensive production of pigs in the centers of irradiation and agroecological management in the areas of agrarian reform settlements in the northern region of Minas Gerais, enabling to expand the source of income of the settlers and greater diffusion and valorization of the native swine breed. To start the extension project, contact with farmers and project exposure was carried out, identification of multiplier agents and formation of family nuclei, after a nucleus of agroecological management of pigs was implanted in the settlements in the municipality of Montes Claros using pure animals of the Piau breed. A survey of the limiting and potential factors was conducted with the community, to consolidate a pig model that best adapts to local specificities. Data were tabulated for one year of collection regarding the zootechnical indexes of the animals. We obtained 8.6 piglets born alive/childbirth/sow; 6.47 piglets weaned/calving/sow in the project, indexes that are higher than the zootechnical indexes obtained in traditional swine management, using national breeds. With the implementation of this sustainable and agroecological production system in the areas of agrarian reform settlements in the Northern Region of Minas Gerais, it was possible to obtain better productive production data, in addition to greater dissemination and valorization of the native swine breed.
