The influence of the pH of feed on the acid-base balance of mink.
The acid-base balance in small carnivores (mink, Mustela vison) was examined during 6 feeding periods, when the same animals were given different feeds during a prolonged time. The feeds consisted of normal farm feed to which different amounts of sulphuric acid-preserved feed and feed silaged with organic acids were added (Tables I--II). When the pH of the feed was decreased to below 5.5, the acid-base balance of the animals was changed and metabolic acidosis occurred (Tables III--V, Fig. 1). On neutralization of the acid-preserved feed a normal acid-base balance could be maintained. However, the growth of the animals was reduced after prolonged feeding with silage as they lost weight during the following periods (Table vii).
