Abbreviations: AIN, AIN-93G; LP, low-protein, EW, early weaning; NW, normal weaning. Values are expressed as means ± SEM for 5–17 mice. Seventeen days after birth: *P ＜ 0.05 vs. AIN-93G, according to the Student's t-test. Twenty-one and twenty-eight days after birth: #P < 0.05 vs. LP-NW, ##P ＜ 0.01 vs. LP-NW according to the two-way analysis of variance (Tukey's test).
