Abstract
the system accumulated variance. These factors are related with the productive process efficiency, relief characteristics, environmental degradation and animals looses. The rearing- fattening systems are classified in four groups, differentiated by the herd size which exploit, the relief where are located, the production process efficiency and the impact they have on the environment. The productive efficiency is low and it correspond with the widespread exploitation alternatives, which are not fit to the environment demands, and with the ability to
use the land on which these production processes are developed. It is possible to implement sustainable alternatives of meat production from cattle rearing-fattening systems, if the production systems are fit to the environments demands where these systems are developed.
Key words: animal husbandry, impact model, productive chain, Amazonia
