Abstract
Marginal potassium supply results in a highly modified MH syndrome and is followed by a reduced K/Na ratio in muscle tissue and a linear association between the K/Na ratio and the metabolic acidosis. The results indicate a reduced anaerobic metabolism during MH.
Retention of Na, K, Mg, and Ca is only slightly different in MHS and MHR pigs fed the same diet. During low K supply renal potassium conservation is maximized and the partial depletion is a likely result of marginal supply as well as increased excretion during repeated stress episodes. A negative result of the halothane test in pigs considered susceptible to partial K depletion should consequently be interpreted carefully.
