Název v původním jazyce

Drinking water indicator evaluation in selected dairy cow farms with different management system in the Czech Republic

Popis výsledku v původním jazyce

The paper evaluates drinking water quality from selected dairy farms (n=30) in the Czech Republic. There were stated pH, conductivity, COD, colour, turbidity, Fe, ammonia ions, nitrites, nitrates, bacteria growing at 36 °C and 22 °C, coliform bacteria, Escherichia coli, macro and microelements. Nitrate content ranged between 1 and 40.7 mg L-1 with an average of 15.6 mg L-1. pH values varied from 5.71 to 8. Chloride conc. geom. means was 7.57 mg L-1. Ca average conc. 58.5 mg L-1, Mg content was 7.9 mg L-1. Cu, Pb, Cr and Ni limit values were not exceeded. Microbiological limit values were exceeded 18x for coliform bacteria, 10x for enterococci, 5x for E. coli. The microbiological colonies growing at 36°C exceeded limit 9x, those growing at 22°C 5x. Thedifference found between chloride concentration in organic (6.56 mg L-1) and conventional farm (18.2 mg L-1) was stat. significant (p < 0.05). A significant dependence was found in nitrate content, which decreased with increasing altitude
