Neural and chemical control of abomasal secretion in sheep.
Abomasal secretion has been collected from Grosskopftype pouches prepared in five adult Karrakul ewes. Feeding caused a marked increase in volume, acidity and pepsin activity, whereas these factors were reduced by starvation. Both insulin-induced hypoglycaemia and electrical stimulation of the vagal nerve supply to the pouch increased the volume, total acid and pepsin secretion. It is concluded that vagal activity is an important factor in the control of abomasal secretion in sheep.
