Unfortunately, regional milk production has been declining in the last decade, and dairy industries are facing difficulties to maintain production over the year, with an idle capacity of around 50% in some regions of Mato Grosso. This study aimed to identify the state pattern of milk yield and seasonal variation in price, analyzing the dynamics of the variables through descriptive and basic statistics. Authors calculated seasonal indexes using moving average in different periods: i) production from 1997 to 2018, and price and production from 2011 to 2018. Our findings indicate that the seasonality of milk yield in Mato Grosso over 1997 ? 2018 spins around 41%, versus 44% from 2011 to 2018. In the same period, the Brazilian indexes reached 20%. In contrast, price seasonality is higher in Brazil (14%) than in Mato Grosso (11%). Considering the price index, we can point out two distinct periods: i) lower payment policy (January to March); ii) higher payment policy (July to September), with peaks in August and February. Regard the price index, the same behavior was seen in Brazil. In conclusion, the seasonality of raw milk production is higher in Mato Grosso concerning the national mean. That oscillation in the supply compromises the processing capacity of regional dairy industries, impacting the price paid to the farmers, reducing dairies production and commercialization.  aDairy animals  aMacroeconomics1 aREIS, J.
