Abstract
Intravenous adrenaline induced reticular extracontractions and rumination within 26 sec in hay-fed, and 184 sec in cube-fed sheep. Regardless of diet, pretreatment with cerebroventricular infusion of kappa-opioid-receptor agonists enhanced this reflex. Control of rumination may involve multiple opioid-receptors, since inhibition of the reflex occurred after mu- and delta-opioid-agonists. Key words: Sheep, rumination, opioid-peptides
