There are different husbandry situations that lead to social isolation of male mice. Besides legal considerations, single housing has a negative impact on behavioural and molecular studies. We have implemented two strategies, the 'companion mouse' and just-weaned male grouping, to reduce the number of male mice housed singly in our facility. We have achieved a progressive reduction (42% in three years) without an increase in aggression.

实施减少单只雄性小鼠的策略。

有不同的饲养情况导致公鼠受到社会隔离。除了法律方面的考虑外，单一住房对行为和分子研究也有负面影响。我们已经实施了两种策略，即“伴侣鼠”和刚断奶的雄性分组，以减少我们设施中单独饲养的雄性小鼠的数量。我们实现了逐步减少（三年内减少了42％），而没有增加侵略性。
