Colonic absorption and secretion of electrolytes as seen in five species of East African herbivorous mammals

Abstract

1. The camel, sheep, goat and donkey were equally efficient in recovering fluids from colonic contents. Zebu cattle were the least efficient. 2. Compared to other species, Zebu cattle demonstrated a reduced sodium and water absorption, and a net chloride secretion. 3. Volatile fatty acid absorption was most evident in the colon of Zebu cattle and the donkey. 4. With the exception of the potassium flux, the camel, sheep and goat demonstrated similar patterns of colonic electrolyte movement.
