通过一系列五个实验来检验关于影响家鼠（小家鼠）雄性和雌性每日排尿量的因素的假设。在代谢笼中收集24小时内的尿液。雄性家鼠的排尿速率是雌性的1.5 - 2.0倍。对于两性以及相同年龄的小鼠，每日平均排尿量随年龄增长而增加；每日排尿量与体重相关。发情期的雌性比间情期的雌性产生更多尿液。在怀孕期的后三分之二阶段，每日排尿量增加，并且在整个哺乳期都保持较高水平。在所测试的密度范围内，密度对两性的每日排尿量均无影响。阉割会降低雄性小鼠的每日排尿量，但雌性卵巢切除并不改变尿液产生的速率。优势雄性比从属雄性产生更多尿液，但雌性小鼠没有类似影响。这些发现对我们理解家鼠尿液的功能和生态用途具有潜在意义。
A series of five experiments was used to test hypotheses about factors affecting excreted urine output per day in male and female house mice (Mus domesticus). Urine was collected in metabolism cages over a 24-hr period. Male house mice excrete urine at a rate 1.5-2.0 times that of females. Daily average urine output increases with age for both sexes and for mice of the same age; urine output per day is correlated with body mass. Females in estrus produce more urine than females in diestrus. Urine output per day increases during the latter two thirds of pregnancy and remains high throughout lactation. Density does not influence urine output per day for either sex over the range of densities tested. Castration reduces urine output per day in male mice, but ovariectomy in females does not alter rates of urine production. Dominant males produce more urine than subordinate males, but there are no similar effects for female mice. The findings have potential implications for our understanding of the functional and ecological uses of urine by house mice.
