The adequade management is the main factor of success in the milk production
activity. In view of this, the objective of this paper was to develop a decision support
tool based in system dynamics to be appled to this activity. To perform the simulations
with the model they were used data from a representative milk production farm of the
state of Minas Gerais, Brazil. The results obtained with simulations showed coherence
with settled previously analysis. The system dynamics showed also to be very helpful
to get a better understanding of milk production systems and to perform strategic
planning
