Formatted abstract
In vivo electrolyte transport and water absorption from the caeca of dehydrated, low-NaCl diet hens are reported. In the absence of luminal glucose or acetate, net electrolyte transport rates and water absorption are small. When physiological concentrations of acetate (40 mM) are included in the perfusate, Na+ transport and water absorption increase significantly (P<0.01): 38±7 μeqNa+/caecum kg·h and 256±33 μl H2O/caecum · kg · h.A similar increase in water absorption occurs with the inclusion of 15 mM glucose in the perfusate (219±30 μl H2O/caecum · kg · h), however both net Na+ and Cl- absorption increase: 28±6 μeq Na+/caecum · kg · h and 21±5 μeq Cl-/caecum kg · h. These pronounced increases in electrolyte and water absorption are not accompanied by any significant increase in transmural potential difference. The data presented establish caeca as important sites in the recuperation of water and electrolytes in dehydrated, low-NaCl diet hens.
