Sažetak
Base economic characteristics (total revenues, total costs, profit and profitability ratio) of the Slovak Pinzgau breed were calculated in this study. Under the actual production and economic conditions of the breed, production system is operated with loss (-457 € per cow and per year) and with negative profitability ratio (-20%). Optimisation of the production parameters on the level defined in the breed standard (5,200 kg milk per cow and year, 92% for conception rate of cows, 404 days of calving interval and 550 g in daily gain of reared heifers) and improved udder health traits (clinical mastitis incidence and somatic cells score) was of positive impact on the total revenues (+34%), on the effective utilisation of costs (+105%) and balanced profit of dairy systems. Next to the positive profitability of the system, higher quality and security of dairy milk products should be mentioned there. Moreover, direct subsidies as an important factor of positive economic result of dairy cattle systems has to be pointed as well. Subsidies should be provided to compensate the real biological limitation of the local breed farmed in marginal areas. However, improvement of the production parameters of the Slovak Pinzgau breed is recommended with the same attention to reach the economic sustainability of dairy production system. To reach economic sustainability of the breed from practical point of view, the farmer activity should be aimed especially to the enhanced herd management.
