摘要: Aiming to assess the sustainability of a terminating swine production system, an energy efficiency study was carried out through 120 days animal lot in commercial system at Ouro Verde do Oeste, State Parana, Brazil. The rate each compound involved process and waste treatment using biodigestor (input output) quantified. matrixes consumption were determined form feeding, electrical energy, human labour, equipment, structures, alive production, biofertilizer biogas. results indicated that activity corresponded industrial agroecosystem, highly specialized, importing great part consumed applied exportation, with 0.38 (Joutput/Jinput). In direct input 95.3% correspond 4.6% piglets, while output 56.8% swine, 30.1% 13%
