Rats were submitted to protein-caloric deprivation during different periods of gestation. Maternal body weight gain, duration of pregnancy and number of offspring were evaluated. Rats of the control group (C) were fed ad libitum (protein 21%), and rats of the experimental groups were fed during all gestational period (D), during the first half (D1) or second half of pregnancy (D2) with a diet containing 1% of protein, and the intake was reduced to 50%. We concluded that malnutrition during pregnancy induced lower maternal weight (C greater than D1 greater than D2 greater than D) and lower number of offspring ( [C = D1] greater than D2 greater than D). No differences were observed in the duration of pregnancy in all groups studied.
在孕期的不同阶段，将大鼠置于蛋白质 - 热量剥夺状态。评估母体体重增加、妊娠期时长和子代数量。对照组（C）大鼠自由进食（蛋白质含量21%），实验组大鼠在整个妊娠期（D）、妊娠前半段（D1）或后半段（D2）喂食含1%蛋白质的饲料，且摄入量减少至50%。我们得出结论，孕期营养不良导致母体体重降低（C＞D1＞D2＞D）以及子代数量减少（[C = D1]＞D2＞D）。在所研究的所有组中，妊娠期时长未观察到差异。
