Protein or energy restriction during late gestation alters fetal growth and visceral organ mass: An evidence of intrauterine programming in goats

The objective of this study was to examine the effects of maternal protein or energy restriction during late gestation on postnatal fetal growth and visceral organ mass of goats. Eighty pregnant goats with similar age (2.0±0.3 yr) and body weight (BW, 20.0±1.0kg before pregnancy) were assigned to 3 dietary treatments during late gestation: control (CON), 40% protein restricted (PR) and 40% energy restricted (ER) diets until parturition, after which offspring received normal diets for nutritional recovery. Kids were killed and visceral tissues were harvested at birth and week 6. Maternal protein or energy restriction decreased (P
