Age and weight at first oestrous and mating, together with body weight and mating outcome, in F1 generation female offspring whose mothers were nutritionally restricted during early (ER; n = 7) or late (LR; n = 11) pregnancy or fed ad libitum (control, C; n = 7). Group data (mean ±s.e.m.) were analysed using one-way analysis of variance (ANOVA) and Bonferroni post hoc comparison.
