[Co-housing in the group with stable hierarchy is not aversive for dominant and subordinate animals].
Behaviour of individuals and their responses to external stimuli are controlled by the micro-social environment in which most mammals are subject to dominant-subordinate relations. Physiological (pain sensitivity, immunological data: thymus and spleen weight, first immunological response) and behavioural (locomotor activity, shuttle-box behaviour) signs were studied in dominant and subordinate male mice of linear hierarchy groups. No significant difference was found between both groups of sings in both groups of the animals. Housing of dominant with subordinate mice seems not to be aversive for both types of the animals.
