A year of sampling 62 troughs and 212 water samples on Central California dairy farms: 47% exceeded the 44 ppm nitrate guideline and 89% exceeded 15 CFU/100 mL E. coli – with nitrate traced back to groundwater and bacteria traced to the cattle themselves.
Water cup cleaning increased daily water intake by approximately 5 L and intake per drinking bout by approximately 2 L in lactating dairy cows, without affecting drinking frequency or milk yield.
132-farm survey in Egypt correlating eight water quality parameters (pH, TDS, hardness, chloride, nitrate, sulphate, TCC, TCFC) with cattle performance indicators (FCR for beef, FE for dairy). Nitrate emerged as the most influential predictor.
