摘　　要：观察了分娩后哺乳雌性棕色田鼠(Microtus mandarinus)与配偶分离7 d、14 d2、1 d后对配偶与陌生雄鼠的行为反应。结果发现,在频次和持续时间上,与配偶分离7 d1、4 d2、1 d的雌鼠对配偶的攻击行为显著低于陌生雄鼠(P<0.05);对配偶的嗅闻及友善行为显著高于陌生雄鼠(P<0.05)。处于哺乳前、中、后期不同阶段的雌鼠对陌生雄鼠攻击水平没有显著性差异(P>0.05)。这些结果说明,在整个哺乳期,雌鼠能够识别配偶,对配偶的记忆不因分离时间的增加而减弱,而且对陌生鼠的攻击水平不会因哺乳阶段的变化而变化,维持高水平的攻击可能与其较强的母性行为有关。In a resident-intruder test, behavior response of lactating Mandarin Voles （Microtus mandarinus ） to strange males and their mates were observed after they were separated from their mates for 7 days, 14 days and 21 days since parturition. Manifested by frequency and duration, lactating females showed a less aggressive behavior to mates than to strange males （ P 〈 0.05）, in contrast, lactating females showed more amicability behavior and sniffling behavior to mates than to strange males （P 〈 0.05）. Aggression level had no significantly difference during early, middle and late lactating periods. These results suggest that Mandarin Vole females were capable of forming selective mate recognition and stranger-directed aggression during the whole lactating period. Although females were in different lactating phase, their aggression level to strangers had no obvious change, which may be related with their strong maternal behavior.
