A Initial weight (purple bars) and weight at independence (light blue stacked bars) of control and treatment pups. B Relative within-litter variance in pup weight in experimental litters (black, solid line) and in unmanipulated litters (gray, dashed line) in which no females were fed during pregnancy. All values and error bars are the mean ± standard error. n.s.: p > 0.05; *p < 0.05.
