SUMMARY Evolution of the concentration of milk solids on dairy farms from NE of Santa Fe Province North-Eastern of Santa Fe, a region characterized by soil and climate constraints, appears to have advantages over other regions of Argentina because of its proximity to large dairy companies. The objective was to determine the evolution of the concentration of milk solids (MS) from NE of Santa Fe (San Justo, Vera, Gral.  Obligado, North of San Javier) from 2003 to 2013. Data of monthly average percentage of milk fat (%MF) and milk protein (%TP) was requested from the dairy industry. The supplied data was processed, statistical analysis (ANOVA) for multiple comparisons within each department was performed, and the variables (Fat and protein) were tested (Tukey test). Considering the values informed at the beginning of the period, there was an increase in the concentration of MS. in milk produced on dairy farms in the region, as evidenced by the increase in % PT in recent years. Similar values to the Pampas region ​​were achieved.
