The development of dairy cattle is directly related to the Brazilian regions according to their particularities of production in function of social, economic and cultural aspects that make up the heterogeneity in the country. The objective of this work was to evaluate milk regions in relation to the zootechnical and economic performance as a function of seasonality in rural properties, seeking to identify milk availability and product price variation throughout the year and the influence of seasonality on behavior costs and revenues from rural properties. A database was compiled and analyzed for dairy producers from a national dairy processing and production industry located in the Midwest, Northeast, South and Southeast regions covering a period of 48 months (July / 2010 to June / 2014), totaling 5,094 producers. For the statistical analysis, the PROC GLM procedure of the SAS software (version 9.4) was used. The results were submitted to analysis of variance and, when a significant effect was observed, multiple comparisons were made between the means of the treatments by the Tukey test, at 5%. Producers in the Central-West region showed the highest total revenue in the Northeast, Southeast and South regions. The gross margin indicator was positive (MB> 0) in all regions and was more significant for producers in the southern region of the winter, summer, spring and autumn and for producers in the Southeast region in the fall. The ROIC was more expressive for the producers located in the South region in the winter and spring seasons. The indicators of zootechnical performance Productivity by area and Productivity by employees were higher for the producers of the South region and smaller for the producers of the Northeast. Producers in the Midwest and Northeast regions showed the highest total revenues of the activity and the higher production costs, while the producers in the South region showed a better balance in terms of profitability and economic efficiency based on the indicators analyzed. There are differences as to the basins analyzed in relation to the economic and productive efficiency in the rural properties. The availability of fresh milk from rural properties occurred throughout all seasons, being most significant in the summer and autumn seasons in the Midwest and Southeast regions, in the spring and winter seasons in the Northeast region and in the winter seasons and summer in the South region. The total cost was higher for producers in the Midwest, Northeast, Southeast and South regions, respectively, with concentrated food, permanent labor and depreciation, the most impacting inputs. Among the indicators of economic performance, the value accounted for by the sale of milk was higher in the Midwest and Northeast regions. Regarding the indicators of zootechnical performance, the producers in the South region were superior to the producers in the Midwest, Southeast and Northeast, respectively
