ANÁLISE ECONÔMICA E AMBIENTAL DE SISTEMAS DE TERMINAÇÃO DE SUÍNOS COM A APLICAÇÃO DOS CONJUNTOS FUZZY

Abstract

The article analyses two hogs finishing systems (deep bedding and manure layer) in respect to economical and environmental aspects. The article focus on the swine production at Vale do Caí region (Rio Grande do Sul State). From the fuzzy sets theory an analytical model is built adding and putting the economical variables in a hierarchical mode — through the calculation of the hogs finishing production costs —, and the variables of the environmental impact — in the air, soil and water sources - allowing the analysis of the total economical and environmental impact of each finishing system. The same model can be used to put in hierarchical mode other breeding and manure control systems.
