Wpływ wielkości stada i wydajności mlecznej krów na koszty produkcji mleka

The study shows differences in the cost of milk production in farms specialized in dairy cattle breeding which ran farm accountancy (according to FADN standards) in 2005. The research was carried out using algebraic function of cost. It was stated that the unit of milk production is influenced both by scale of production (measured on the amount of herd) and milk yield. The increase of scale of production has been caused by decreasing at the beginning and thereafter by increasing of unit cost of milk production. It has been shown that higher milk yield, irrespective of scale of production, causes the decrease of unit cost. Bigger milk yield, irrespective of scale of production, causes decrease of unit cost.
