Plasma vitamin C concentrations in parent animals on the day of mating and day of delivery. At mating, optimal sires and dams (full circles, n = 10 male, n = 9 female) and low sires and dams (open circles, n = 10 male, n = 7 female). At delivery, optimal dams (full circles, n = 9) and low dams (open circles, n = 8). Data are presented as individual points with group means ± SD. An asterisk indicates significance between bars linked with black lines; **** = p < 0.0001. Data were analysed using unpaired t-tests with Welch’s correction for heterogeneity of variance applied.
