Shipping Male Mice
One of the problems often encountered with group-housed male mice is excessive aggression which can lead to negative affects both on the well-being of the animals and on the validity of experimental results. In order to minimize the risk of male aggressiveness, Inotiv is housing male mice as cage mates from weaning onwards and will not mix these with unfamiliar mice upon shipping. Nevertheless mice can show aggressive behavior upon arrival and housing at the customers facility due to differences in husbandry and hierarchy. It is therefore advisable to not mix male mice from different delivery boxes and to house them in small groups (three to five animals per cage) as this will reduce the incidents of stressful situations.
