There was no difference between rearing group, species or drinking condition in alcohol preference (A). There was no significant difference between rearing groups in alcohol consumption, but there was a significant difference between species (B), where meadow voles consumed less alcohol than prairie voles (p<0.05). There was a significant effect of drinking condition on alcohol consumption, where animals consumed less in the non-social condition than the social condition (p<0.005). There was no interaction between group or species and drinking condition. There was no significant difference between rearing group or species on alcohol volume consumed (C) or total fluid volume consumed (D), but there was an effect of drinking condition where less was consumed during the non-social period than in the social period (p<0.05).
