DairyNZ Comment:

21 Dec 2016
  • Stock water supply becomes critical during summer. A recent DairyNZ measurement of water use on 35 farms found an alarming amount of water leakage. On half of the farms, leakage of greater than 21%, (and up to 50%), of stock drinking water was identified. In addition to the cost of pumping extra water that is never used, this reduces the effectiveness of using the water supply for preventative zinc dosing for facial eczema (FE). Water leakage is part of the explanation why another DairyNZ funded study showed that over 50% of the cows that were on farms supplementing with Zn, had a serum Zn level less than the level required to provide protection from FE. These results suggest that what is happening on many farms is not controlling the effects of exposure to facial eczema effectively. A plan for reducing the cost of FE exposure on your farm might initially involve some attention to the water reticulation system.
