  1. 1Barrow lysine concentrations based on the equation: g/SID Lys:Mcal = 0.000146 × (BW, kg)2 - 0.0377 × (BW, kg) + 4.352.
  2. 2Gilt lysine concentrations based on the equation: g/SID Lys:Mcal = -0.00000094 × (BW, kg)3 + 0.000306 × (BW, kg)2 - 0.0435 × (BW, kg) + 4.414).
  3. 3Percentages are for diet containing 3,350 kcal ME/kg using NRC [23] nutrient values.
