ABSTRACT
The effect of dietary fibre on abomasal secretion and gastrin postprandial level was studied in
four sheep. Two isonitrogenous diets differing only in crude fibre content (LFD, 14% or HFD, 23%)
were used. Volume, hydrogen and chloride ion output, sodium concentration in pure abomasal juice
were higher in HFD treatment. Pepsin activity and pH was lower in that group, while both treatments
did not affect protein output and potassium concentration. Postprandial gastrin serum concentration
was elevated at 30, 60 and 120 min in HFD as compared to LFD group. Results suggest that fibre
stimulates abomasal secretion and elevates gastrin level.
