    The aim of the study was to compare profitability of raw milk production in two herds, one of Jersey cows (J) and the other of Polish Holstein-Friesian Black-and-White cows (PHF), owned by the same economic entity. In this study daily actual and standardised (FCM and VCM) milk yields as well as milk composition were compared between Jersey and PHF cows in terms of age groups (primiparous vs. multiparous cows). Within the Jersey and PHF breeds for each year of the analysed period a balance of revenue and costs from raw milk production was prepared, while production indexes were calculated, i.e. total production cost of 1 l milk, net income from cattle production, net income from the production of 1 l milk, the value of milk production per cow and net income per cow. A more advantageous actual daily milk yield, daily milk yield expressed as FCM and VCM as well as the value of daily milk production were recorded for primiparous PHF cows in comparison to their Jersey peers. In that age group of cows in terms of milk composition, greater contents of fat, protein, solids as well as somatic cell count were found for primiparous Jersey cows. In the case of multiparous cows except for daily FCM and somatic cell count (means did not differ significantly), similar dependencies were recorded for the analysed parameters as those observed for primiparous cows. When comparing profitability indexes for raw milk production in the years 2014–2016 between the Jersey and PHF herds it was shown that in 2014 and 2015, despite lower average milk yields, net income from the production of 1 l milk was the greatest in the Jersey herd, while in 2016 a more advantageous value of this index was recorded for the PHF cows in relation to Jersey cows. In conclusion it may be stated that costs incurred for raw milk production are dependent on specific conditions in a given herd or farm, this it is a rational approach to continuously reduce outlays on milk production combined with improvement of production and functional traits in cows. If the total production costs per 1 l milk in the Jersey and the PHF herds are comparable, greater profitability of raw milk production is observed for Jersey cows. This results from the higher price for sale of milk coming from cows of this breed.
