Values shown as means ± SE. Where n differs from column heading, it is given in parentheses. Leptin RIA used human insulin in standard curve; antibody efficiency may be different for pig leptin. Log fasting plasma insulin/log fasting plasma glucose × 100; higher values reflect higher sensitivity. HE, human equivalent; QUICKI, qualitative insulin-sensitivity check index.

^*Significant data previously published (18).

^†P < 0.05, glucose, maternal diet effect in males only; QUICKI, postweaning diet effect in females only.

^‡P < 0.05, QUICKI, sex effect.

^§P < 0.05, QUICKI, postweaning diet effect.
