Abstract

Stimulation of ileocaecal digesta flow by dietary fibre is related to a reduction of the dry matter concentration of the digesta. Levels of sodium bicarbonate, Na and K passing to the large intestine rise. With limited dietary Na, an equimolar intraluminal exchange of Na and K and high levels of aldosterone in the serum were found. Exogenous intravenous aldosterone moderately affected levels of Na and K in the caecum. The effect of angiotensine was limited.
