The influence of infantile handling, age and strain on alcohol selection in mice

Abstract

Male mice from three inbred strains (C57B1/10J, BALB/cJ and C3H/21bg) were assigned to infantile handling or control conditions. In a cross-sectional developmental design, handled and control mice were tested for two-choice selection of 10% (v/v) ethanol vs. tap water at 60, 90 or 120 days of age. The volume of fluid consumed from both tubes was recorded for fifteen days. In 60 day old mice, handling produced a trend toward increased total fluid consumption in the C57 mice and a trend toward increased ethanol selection in the BALBs. In 90 day old mice, there were trends noted toward handling-related decreased fluid consumption in BALBs. Also noted was a trend toward handling related increased ethanol selection in C57 mice. In 120 day old mice, a handling-related increase in alcohol selection was noted in the C3H strain.
