[Poststressor change in attractiveness of mice odourgens].

It was shown, that under physiological conditions, intact noninbred mice or high-inbred mice-testers in reaction of preference-avoidance prefer volatile components secreted by mice of a genetically identical group. After exposure to stress factors, mice release with urine the volatile components, which are more preferable by testers than the volatile secretion of intact mice indepedently of the genotype of mice.
