Abstract

Measured daily food and water intake during 24-hr food deprivation in 181 adult male rats of 15 inbred strains and 1 outbred stock of Rattus norvegicus. Strain differences in absolute and relative food intake were moderate but significant, whereas strain differences in absolute and relative water intake under both conditions were dramatic. During food deprivation, some strains showed little depression of daily water intake, while other strains consumed less than 20% of their usual ad lib intake. Both genetic and environmental explanations for the divergent patterns of water intake during food deprivation are presented. In light of such strain differences, generalizations about the drinking behavior or water intake regulation of the rat must be made with caution.
