The result depicted tha cattle breeding is an important source of environmental impact. Moreover, there was a significant change in the system due to the economic non-viability of certain activities throughout the opimization assessment. This study demonstrates that LCA and linear programming constitute important tools for the analysis and improvement of the social, environmental and economical performance of the family farm production systems.  aAgricultura Familiar  aProgramação Linear1 aXAVIER, J.
