Abomasal secretion and gastrin blood level in sheepfed diets with different fibre content
TL;DRAbstract
The effect of dietary fi bre on abomasal secretion and gastrin postprandial level was studied in four sheep. Two isonitrogenous diets differing only in crude fi bre 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 fi bre stimulates abomasal secretion and elevates gastrin level.
