Abstract

Aggressive and submissive behaviour was studied in CBA/Lac and C57BL/6J strains of mice during long-term intermale interaction with syngenic partners. It was shown that the aggressiveness of aggressive C57BL/6J animals was more expressive than that of CBA/Lac' ones. The structure of submissive behaviour of this strains' encounters was also significantly different. Prolonged-defeat experience changed the character of submissive behaviour of C57BL/6J, but not of CBA/Lac' ones. Aggression of dominant animals considerably decreased in both strains. It is suggested that CBA/Lac and C57BL/6J mice had different mechanisms of suppression of intermale aggression.

摘要

在与同基因伙伴进行长期雄性间相互作用期间，对CBA/Lac和C57BL/6J品系的小鼠的攻击性行为和顺从性行为进行了研究。结果表明，具有攻击性的C57BL/6J动物的攻击性比CBA/Lac动物的更明显。这两个品系相遇时顺从行为的结构也存在显著差异。长期失败经历改变了C57BL/6J的顺从行为特征，但未改变CBA/Lac的。在这两个品系中，占主导地位动物的攻击性均大幅降低。提示CBA/Lac和C57BL/6J小鼠具有不同的抑制雄性间攻击的机制。
