Sodium-Bisulfate and Ammonium Chloride for Mink in the Growing Period

Over the years we have tested the addition of various acids and other compunds to the mink feed for their ability to lower the urinary pH, and thereby prevent cystitis and urinary calculi.
Urinary pH should preferably be in the interval of 6.0 to 6.6 (Case et al, 1995).
In the present trial we tested the long term effect of adding 0.5 % Na-bisulfate or 0.2 % ammonium chloride during the growing period.
