Data are expressed as mean ± SEM with the number of dams/litters in parentheses. Values with different superscripts are significantly different from each other (p<0.05, one way ANOVA).

*

significant difference between D16 and D19 pregnant dams (p<0.05, t-test).

Organ weights and DEXA results were expressed as % of total body weight for NP females and of hysterectomised for pregnant dams.

§

skeletal muscle fat content was measured on samples pooled from 3-5 animals from each group.
