Guhad, F. A., Hau, J.

Abstract

Three groups of adult male rats were housed under differentconditions (singly housed, paired with a female, and group housed). The animals were conditioned for the saliva collection by presenting a chocolate reward after session and saliva was collected by soaking filter paper discs (5 mm in diameter) with saliva directly in the rats' oral cavity.
