FIGURE 2 Stable isotope infusion protocol. Before start of intravenous infusion and bolus feeding NaH¹³CO₃, l-[1-¹³C]-leucine, [¹⁵N₂]-urea, formula, and l-[²H₇]-leucine were primed at 5 µmol/kg, 40 µmol/kg, 15 µmol/kg, 15.2 mL/kg, and 40 µmol/kg, respectively. Formula refers to the diet of the group each piglet was assigned to. Vertical arrows indicate time points when blood samples were taken for tracer analysis.
