Increasing water intake by addition of NaCl to mink feed

One of the biggest disease problems in June / July is connected with the urinary tract (Hansen et al., 2008; Clausen, 2006). It has been suggested that you can make mink kits drink more and thereby urinate more, by adding a surplus of salt (NaCl) to the feed. This should help to reduce the formation of urinary stones.
However, it should be noticed that to high amounts of NaCl can be toxic. The symptoms on NaCl toxicity is reduced feed consumption and body weight gain, a dark diarrhoea, rough coat, crusty nose and eyes, irritability in the early stage, and lethargy in the later stages. (Restum et al., 1995).
