Body weight gain (g) and growth rate (%) on different days during the preweaning period. Reference day was considered postnatal day, pnd, 9. Rats were exposed to a single episode of early maternal deprivation (24 h on pnd 9, MD) or not deprived (control group, Co). Data are expressed as mean ± S.E.M and were analyzed by a repeated measures two-way ANOVA, < 0.05. ^BGeneral effect of the neonatal condition. = 5 litters per experimental group.
