Analiza op?acalno?ci produkcji mleka w latach 2001-2012 na przyk?adzie RSP ?Przysz?o??” z uwzgl?dnieniem zmiany systemu utrzymania krów

摘要

The aim of the study was to determine profitability of milk production over several years in a herd of about 100 cows, taking into account changes in the housig system from the tethering to free stall in the “Przysz?o??” Farming Cooperative. The study considered costs and income obtained from milk production and assessed profitability of this direction of agricultural activity. The profit being an equivalent of net income was adopted as the final financial result. Among milk productivity indexes the following were calculated: cost of direct production of 1 l milk, total production cost of 1 l milk, profit generated by 1 l milk, profit per 1 cow and per 1 milking cow, the ratio of sale price to production cost of 1 l milk and production profitability index. The above mentioned parameters of milk production efficiency were calculated for the analysed years and for the period of tethering and free stall housing. Level of profitability of milk production in the “Przysz?o??” Farming Cooperative was varied, which was conditioned by decreasing production costs and the price of its sales each year. The most advantageous values of milk production profitability index were recorded in 2001 and 2005. With free stall housing system of cows milk production increased increasing the cost of its production at the same time. The main factors causing a reduction of milk production profitability in the free stall system in comparison to the tethering system were connected with significantly higher expenditure on fodder (mainly ready-purchased). The transition from the tethering management system to the free stall system resulted in relatively high values of milk production efficiency indexes at simultaneous reduction of labour consumption and considerable improvement of animal welfare.
