Study design. Pregnant gilts were assigned either to a normal energy (NE, n = 9) or a high energy diet (HE, n = 5) diet throughout gestation. After birth(farrowing), piglets stayed with their moms throughout lactation period (21 days after birth). After weaning on day 21, piglets were assigned to postweaning diets. A total of eighteen piglets from NE gilts were assigned to post-weaning diets (10 to NE and 8 to HE). Twelve piglets from the HE gilts were assigned (6 each NE and HE) to post-weaning diets
