This study describes infant socialization in captive parent-young units of the caviomorph rodent Octodon degus. Types of parent-young contact (huddling or squatting) and social interaction (body nosing and accompanying behaviors) are described and their ontogenetic trends examined between postnatal Days 1 and 46. Fathers spent less time than mothers in contact with the young. Mother-young contact decreased postnatally, whereas the amounts of mother-young and father-young social interaction, measured in terms of body-nosing exchanges, showed a continuous increase postnatally; sibling interactions also showed a continuous increase. Father-young interactions tended to be dominated by the father. Young reared with the father cohabiting huddled less with their mother, and engaged in less body-nosing, than young reared in the father's absence. Observations suggested that paternal control of the young may curb juvenile interactions. Young observed without their parents in an unfamiliar enclosure did not groom or "play" as in their home cage with parents present, but engaged in relatively more vocalizing, neck-nosing and forepaw-clasping.
本研究描述了豚鼠科啮齿动物八齿鼠圈养亲子单元中的幼崽社会化情况。描述了亲子接触的类型（蜷缩或蹲伏）和社交互动（身体嗅探及陪伴行为），并研究了出生后第1天至第46天之间它们的个体发育趋势。父亲与幼崽接触的时间比母亲少。母婴接触在出生后减少，而以身体嗅探交流衡量的母婴和父子社交互动量在出生后持续增加；兄弟姐妹间的互动也持续增加。父子互动往往由父亲主导。与父亲共同生活的幼崽与母亲蜷缩的时间更少，身体嗅探也更少，相比那些父亲不在身边长大的幼崽。观察表明，父亲对幼崽的控制可能会抑制幼崽间的互动。在陌生围栏中观察到的没有父母陪伴的幼崽，不像在有父母的家笼中那样梳理毛发或“玩耍”，而是更多地发出叫声、进行颈部嗅探和前爪抓握。
