Following vomeronasal organ removal or sham surgery at 4-7 days of age, male guinea pigs were tested for responsiveness to conspecific chemical uses as infants and again as adults. In the first experiment, vocalizations in response to soiled home cage bedding and male bedding were monitored twice prior to surgery and twice weekly for four weeks. Home cage cues elicited more vocalizations than did male bedding in both groups; however, there was no effect of vomeronasal organ removal. When tested as adults in a second experiment, animals without vomeronasal organs exhibited depressed investigative responsiveness and vocalizations to female genital smears. The data from the first experiment fail to indicate a role for the vomeronasal organ in infantile response to conspecific odor. However, the second experiment demonstrates that adult responses to similar odors are substantially depressed by an absence of the vomeronasal organ.
在4至7日龄时进行犁鼻器切除或假手术后，雄性豚鼠在婴儿期和成年期都接受了对同种化学信号反应能力的测试。在第一个实验中，在手术前对豚鼠对弄脏的饲养笼垫料和雄性垫料的反应进行了两次监测，术后四周每周监测两次。在两组中，饲养笼提示引发的叫声都比雄性垫料多；然而，犁鼻器切除没有产生影响。在第二个实验中，当作为成年豚鼠进行测试时，没有犁鼻器的动物对雌性生殖器涂片的探究反应和叫声减少。第一个实验的数据未能表明犁鼻器在婴儿对同种气味的反应中起作用。然而，第二个实验表明，成年豚鼠由于没有犁鼻器，对类似气味的反应会大幅降低。
