Normorphine and naloxone were administered via selective routes in sheep and goats. The results



with noimorphine indicate the presence ofboth (1) a central action depressing frequency and am-

plitude and, (2) a peripheral action



-

probably on the intramural plexus

-

depressing only the



amplitude of the cyclical reticulo-ruminal contractions.



Key words: Sheep, goat, normorphine, naloxone, forestomach motility
