The milk market changes in Brazil, occured in the last few decades, have challenged the milk producers, especially the smaller ones in relation to milk quality improvement, the reduction of production costs, the adoption of modern practical management technologies and efficiency and productivity gain. The economic sustainability of the producers depends, in great measure, on their success in responding positively to these challenges. This work has aimed to evaluate the technical and economical efficiency of the family dairy production in settlement projects of agrarian reform in the city of Unaí-MG. Information on the production of sixteen producers were collected during an eleven-month period. For evaluating the efficiency, it was used Data Envelopment Analisys (DEA), which is based in the linear programming to identify the producers that are more efficient in the use of the inputs. The calculations were carried through with software SIAD 2.0. Only four producers with maximum efficiency were identified. The efficiency of the inefficient producers was of 77%. It means that this group could reduce its inputs in 23% on average, without compromising the production. Generality, the benchmarks producers present better results in the index for costs of production, daily production, land productivity, efficiency in the use of concentrated for feeding the flock and in the gross margin by area. The simulations made indicate an efficiency gain of 28,04%, when the adjusts showed by the model were made.
