Pregnant rats, Wistar strain, were treated from day 11 of gestation with synthetic diets containing different amounts of protein. The Group of rats fed a severely deficient protein diet (4% of casein, 2% of lactalbumin) showed reduced hematocrit, hemoglobin, total protein and an expressive increase of gamma globulins compared with rats treated with normal or elevated protein levels. Weight gain during pregnancy was higher for rats which received a larger amount of protein; on the contrary those that were subjected to malnutrition had no weight gain and bore prematurely with high percent of foetal mortality.
选用Wistar品系的怀孕大鼠，从妊娠第11天开始用含不同蛋白质含量的合成饲料进行喂养。与喂食正常蛋白质水平或高蛋白质水平饲料的大鼠相比，喂食严重缺乏蛋白质饲料（4%酪蛋白，2%乳白蛋白）的大鼠组，其血细胞比容、血红蛋白、总蛋白降低，γ球蛋白显著增加。孕期摄入较多蛋白质的大鼠体重增加较多；相反，那些营养不良的大鼠体重没有增加，并且早产，胎儿死亡率很高。
