SID Lys requirements for sows estimated by the InraPorc and NRC models. Both models were parameterized to represent similar conditions. A second parity sow weighing 165 kg at service was fed 2.21 kg/d until 90 d of gestation and 2.61 kg/d thereafter until farrowing (13.5 pigs/litter, 1.4 kg birth weight). The body weight after farrowing was 210 kg and the sow consumed on average 5 kg/d during lactation (11.5 piglets weaned, 230 g/d weight gain during 21 d of lactation).
