The study were performed on 4 rams with the „small abomasum” created according to Pavlov’s method. They were fed at 8 o’clock, and the experiments started at 10 o’clock i.e. at the moment of the highest abomasal juice secretion. Before examinations the animals were fitted with an epidural catheter to the external jugular vein. After collection of 3 consecutive 20 min. initial samples of abomasal juice, propranolol at a dose of 1 mg/kg was intravenously injected and the next four samples of juice were collected. In each sample the volume (ml), acid output (mmol) and pepsin output (mA) 20 min.⁻¹ were tested. It was found that in fed sheep β-adrenergic receptors have a stable inhibiting influence on abomasal juice secretion. Removal of this effect by propranolol, of β-adrenergic antagonist, increased the level of secretion of abomasal juice in sheep.
