The influence of environmental enrichment on the behaviour of the mouse has been studied in two inbred strains (C57BL and BALB/c). Male mice of each of the two strains were subjected to behavioural tests after being housed for two months either under standard housing conditions or in an enriched environment. The results of the behavioural test indicated that the C57BL mice housed in the enriched environment were more reactive and alert compared to mice housed in the standard environment. In the BALB/c mice results may be interpreted as if enriched environments lead to an increased level of anxiety. It is concluded that environmental enrichment has a strain specific effect on the behaviour of mice.
在两个近交系（C57BL和BALB/c）小鼠中研究了环境丰富化对其行为的影响。将两个品系的雄性小鼠分别置于标准饲养条件或丰富环境中饲养两个月后，进行行为测试。行为测试结果表明，与饲养在标准环境中的小鼠相比，饲养在丰富环境中的C57BL小鼠反应更灵敏、更警觉。对于BALB/c小鼠，结果可以解释为丰富环境会导致焦虑水平升高。得出的结论是，环境丰富化对小鼠行为具有品系特异性影响。
