Journal of Endocrinology (2000) 165, R1-R6 that half were permitted to consume 35% more feed during the second quarter of pregnancy. Leptin mRNA abundance in adipose tissue (P=0.015) and plasma leptin concentration (P=0.01) were higher in progeny from mothers provided with more feed. Body weight at birth was negatively correlated with the abundance of leptin mRNA in subcutaneous fat at 59 days of age (P=0.01). This study shows for the first time that maternal nutrition during pregnancy programs

Since nutrition during pregnancy can affect birth weight, the hypothesis that feed intake during pregnancy alters leptin expression in progeny was examined. Leptin mRNA was measured in subcutaneous adipose tissue and leptin protein was measured in blood plasma from 59 day old female pigs whose mothers were fed at the same restricted rate except R2
