This study aimed to characterize and identify the performance and cost-effective milk production units within a radius of 65 km from Pocos de Caldas (Minas Gerais), providing information about the model production system in the region and its indicators. We analyzed data from 1,535 animals distributed in seven farms. The analysis included period July 2005 to May 2008. The data were analyzed descriptively. The variables were divided into: production characteristics, such as average duration of lactation (DML), daily milk production (PDL), land productivity and productivity per cow in milk (PLVL), reproductive characteristics such as age at first calving (IPP), calving interval (IP) and heat interval (IC); economic data such as gross margin (MB), net margin (LM) and rate of return on invested capital (TR). In these systems, the average value of DML, PDL, PL305, PLPL, IPP, IP and IC was 11 months, 1,739 L/day, 5,805 L/cow, 19 L/cow/day, 35 months, 419 days and 39 days respectively. We found a direct effect of technical data on economic indicators. The technical data that most affected the economic indicators were RVL/VT, RVL/Reb, DML, PL305 and PT, with results next to 65%, 30%, 10.4 months, 4,481 kg and 7,602 L/ha/year in Farms with low economic performance and 72%, 40%, 11.3 months, 7,005 kg and 18.038 L/ha/ano in Farms with attractive economic performance.
