The total daily amino acid (AA) requirements for pregnant sows are based of Lys which is the first-limiting AA in swine diets. The SID Lys requirements are estimated by the NRC (2012) gestating sow model as the sum of those required for maintenance and protein retention divided by the efficiency of SID Lys utilization. The NRC (2012) gestating sow model assumed AA efficiency is constant across stages of gestation and parities; however, this does not reflect the change in metabolic demand of various age sows at different stages of gestation. Therefore, an experiment was conducted to evaluate the efficiency of …
