Three experiments were designed to test the effects of food deprivation during various phases of the reproductive cycle on fertility and fecundity of the dams and on the age of sexual maturation and body growth of their female progeny. Food deprivation consisted of removal of all food every other day. Animals were deprived of food either during the period prior to pairing, during the period between pairing and conception or during gestation. Both fertility and fecundity were affected by food deprivation in some, but not all manipulations. The female progeny of food-deprived females reached puberty significantly later than the progeny of non-deprived dams when the food deprivation occurred during the week prior to pairing and up until successful insemination after pairing with a fertile male, but not when food deprivation occurred at other times during the reproductive cycle. Body growth did not differ in the daughters of food-deprived dams across the treatments for any of the experiments.
设计了三个实验来测试在生殖周期的不同阶段进行食物剥夺对母鼠生育力和繁殖力以及其雌性后代性成熟年龄和身体生长的影响。食物剥夺包括每隔一天移除所有食物。动物在配对前、配对与受孕之间或妊娠期被剥夺食物。在某些但并非所有操作中，生育力和繁殖力都受到食物剥夺的影响。当在配对前一周直至与可育雄性配对后成功授精期间进行食物剥夺时，食物剥夺的雌性后代比未被剥夺的母鼠的后代显著晚达到青春期，但在生殖周期的其他时间进行食物剥夺时则不然。在任何一个实验的所有处理中，食物剥夺的母鼠的女儿的身体生长没有差异。
