The aim of the present study was to investigate whether oral potassium supplementation during food deprivation could stimulate rumen electrolyte absorption and maintain plasma electrolyte concentration. Eight goats were subjected to food deprivation in combination with intrarumen loads of potassium chloride or, as a control, mannitol in a change-over design. In addition, four KCI- and four mannitol-treated goats were given an extra KCI load towards the end of the experiment. Food-deprived goats which were given KCI maintained their plasma concentration of Na and CI, while plasma K concentration increased from 3.6 mM to 4.4 m.M. In control goats receiving mannitol during food deprivation, the plasma concentration (mM) decreased from 144 to 140 for Na, 105 to 100 for CI and from 3.8 to 3.6 for K, but concentrations were restored when these goats were given a load of KCI. The plasma renin activity was suppressed in food-deprived goats receiving KCI, while those given mannitol showed increased activity. It is suggested that the hyponatraemia which occurs in food-deprived ruminants is mainly caused by diminished K intake.
