Sažetak
Water quality for cattle and horse watering at a family farm was analysed in the study. Water samples were collected once per month from June to December from thermo drinkers connected to water network. The following water quality parameters were analysed: temperature, colour, pH, potassium permanganate consuming capacity, ammonium, nitrite, nitrate, chloride, aerobic mesophilic and coliform bacteria. Values of potassium permanganate consuming capacity and ammonium ions as chemical parameters which indicate the amount of organic substance in the water exceeded maximum permissible levels during the summer in the water for cattle and horse watering; nevertheless, significantly higher (p<0.05) concentrations were determined in the water for the cattle. Also, during the month of August increase in the nitrite concentration above the permissible levels was observed in the water for the cattle watering. In the water for both animal species positive coliform bacteria and increased number of meso philic bacteria above the permissible level were recorded during total study period. The number of mesophilic bacteria was significantly higher (p<0.05) in the water for the cattle watering during the summer, and in the water for the horse watering during the winter. Study results of the water quality suggest that the cattle preferred to drink from thermo drinker during the warmer period, while horses during the cooler period. Moreover, the values of the observed parameters of the water quality for the watering of both animal species point to the necessity of disinfection of the thermo drinkers and more regular cleaning.
