Sex and breed-dependent organ development and metabolic responses in foetuses from lean and obese/leptin resistant swine.

The present study aimed to determine the effects of breed and sex on growth patterns and metabolic features of advanced-pregnancy foetuses exposed to the same environmental conditions. Thus, at Day 62 of pregnancy, swine foetuses from an obese breed with leptin resistance (Iberian breed) were compar...
