The mean plasma concentrations of leptin during pregnancy
(0–26 days) were lower (p < 0.05) in all restricted groups (1.3,
1.7, and 1.9 ng/ml in R1, R2 and R3 groups, respectively) than in
control group (2.3 ng/ml). Group was not significant for insulin concentrations
although an interaction between time and group was
observed (p < 0.05)
