Role of neurotensin in the regulation of gastric motility in healthy conscious sheep

The goal of present study was to determine the effects of the intravenous (i.v.) administration of neurotensin (NT) on the ovine forestomach and abomasal motility in conscious sheep. NT injection at 0.3 nmol/kg slightly raised abomasal pressure, although the effect was not dose-dependent. A bolus i.v. injection of NT at 1 or 3 nmol/kg significantly inhibited the amplitude of cyclic ruminal contractions. NT injection did not alter omasal...
