a Measurements on offspring of high body condition score (HBCS) and low body condition score (LBCS) ewes. Area under the curve (AUC) calculations are from baseline. Data are shown as the mean ± standard error of the mean (SEM) except for basal insulin which is shown as the geometric mean (95% confidence interval [CI]). The number within indicates where n differs from column heading.
