Utilization of SID Lys in a first parity sow as predicted by the InraPorc model. The sow is offered a gestation diet at a restricted level up to the last week of gestation. The gestation diet is then replaced by a lactation diet (with a higher SID Lys content), which is offered ad libitum during lactation. The gestation diet is offered again at a restricted level during the interval between weaning and conception.
