Abstract
A technique for reversible re-entrant cannulation of the parotid duct in sheep is described. A tube is inserted into the excretory duct via the papilla, is brought through the cheek, and connected to a three-way stop-cock positioned on the neck. A return tube from the stop-cock is passed through the cheek at a point forward and dorsal to the first tube. Sheep were maintained with such unilateral parotid cannulae for 3 mo or shorter periods. Saliva flow rates are comparable with values reported using other techniques. Removal of the tubing reverses the animal to its previous normal functioning state. This is an advantage over previously described procedures. Key words: Cannulation; parotid gland; parotid secretion; salivation; ruminants
