SID Lys and SID Thr:Lys requirements for growing pigs estimated by the InraPorc and NRC models. Both models were parameterized to represent similar conditions and growth was simulated between 20 and 140 kg of body weight for a pig consuming 2.24 kg/d and with an average daily gain of 785 g/d. The feed intake (gamma function of maintenance) and protein deposition (Gompertz function) curves used in InraPorc were parameterized in the NRC model as third-order polynomials with similar shapes as the functions used in InraPorc.
