    The aim of this study was to analyse milk production profitability over a period of more than a decade in a commercial farm in terms of two periods: prior to Poland's accession to the EU (from 1998 to April, 2004) and after accession (from May, 2004 to 2012). Obtained source data made it possible to calculate mean annual values for the following items in these calculations: the number of cows, production of milk sold, production of milk to be fed, milk sales price, calf rearing, sales of slaughter cattle, sales of culled cows, total income from milk production, direct costs, feed costs, handling costs, indirect costs including depreciation, total milk production costs, direct costs per 1 l produced milk, total costs per 1 l produced milk, profit/loss from cattle production, profit/loss from 1 l produced milk, value of production per 1 cow, profit/loss from milk production per 1 cow, the ratio of milk sales price to production costs and profitability index for milk production. Within this study data were also collected on profit/loss per 1 l produced milk and milk production profitability indexes in the analysed years. It was shown that following Poland's accession to the EU in the analysed farm statistically highly significant changes were observed in income and costs connected with the production of raw milk. Values of these parameters increased in comparison to the previous period. An increase was recorded in milk production and profit per 1 cow, which was most probably a consequence of breeding work and gained genetic progress and increased productivity in the herd. However, when comparing the period before and after Poland's accession no statistically significant differences were found for profit/loss per 1 l produced milk and milk production profitability indexes. The post-accession period in relation to the previous period was characterised by more dynamic changes in profitability indexes for raw milk production, which resulted in a lesser stability in profitability for this branch of animal production.
