Change over time in mean values (±S.E.M.) of the occipito-nasal length (panel (A)), biparietal diameter (panel (B)) and thoracic and abdominal circumferences (panels (C) and (D), respectively) during the early postnatal development (0 to 30 days old) in piglets from control (group C; black dots with discontinuous lines) and sows treated with metformin during pregnancy (group METF; black dots with continuous line). Asterisks denote significant differences between groups (* p < 0.05; ** p < 0.01).
