Effects of olfactory bulbectomy on social behavior in male guinea pigs were studied. Both brief-exposure pairing techniques and a group-living observation period were employed to test for disruption. During short-term testing sessions bulbectomized animals courted females less than but mounted them as frequently as control subjects. While the groups did not differ in fighting behavior during short-term tests, control subjects scent-marked more frequently. Subsequently, animals were observed as same-treatment pairs living continuously with females, and behavior was sampled over a 3-wk period. Under these conditions bulbectomized males, unlike controls, failed to form dominance orders, exhibited virtually no intermale aggressive activity, had markedly depressed sexual activity, and scent-marked rarely. It is concluded that olfactory bulbectomy profoundly alters the behavior of male domestic guinea pigs and that hose alterations are most evident when experimental subjects are observed in a species-typical group-living environment.
研究了嗅球切除对雄性豚鼠社会行为的影响。采用短暂暴露配对技术和群居观察期来测试行为破坏情况。在短期测试阶段，嗅球切除的动物向雌性求爱的次数比对照组少，但骑跨雌性的频率与对照组相同。虽然在短期测试中两组动物的打斗行为没有差异，但对照组动物标记领地的频率更高。随后，将动物作为同处理对与雌性持续生活在一起，并在3周内对行为进行采样。在这些条件下，与对照组不同，嗅球切除的雄性动物未能形成优势等级，几乎没有雄性间的攻击行为，性活动明显降低，且很少标记领地。得出的结论是，嗅球切除会深刻改变雄性家养豚鼠的行为，并且当在典型的群居环境中观察实验对象时，这些改变最为明显。
