A series of tests were conducted to determine whether infant degus (Octodon degus) will (a) show sensitivity to maternal olfactory cues and/or (b) discriminate between a novel adult lactating female and their mother. The pups showed no preferences when exposed to an array of different olfactory stimuli but did spend significantly more time in proximity with the novel lactating female than with their mothers. It is hypothesized that the communal rearing systems which are apparently characteristic of degus in the wild, coupled with the novelty of the lactating female, may account for these results.
进行了一系列测试，以确定幼小的八齿鼠（Octodon degus）是否会（a）对母体嗅觉线索表现出敏感性，和/或（b）区分陌生的成年泌乳雌性和自己的母亲。幼崽在接触一系列不同的嗅觉刺激时没有表现出偏好，但与陌生的泌乳雌性待在一起的时间明显比与自己的母亲待在一起的时间更长。据推测，野生八齿鼠明显具有的群居饲养系统，再加上泌乳雌性的陌生性，可能是导致这些结果的原因。
