Outline of the tracer infusion and blood sampling protocols. After 15 min of blood sampling at baseline, pigs were fed at hourly intervals with intravenous infusion of NaH13CO3 for 2 h followed by a 6-h infusion of [1-13C]leucine. Blood samples were obtained every 1 h throughout the 8-h tracer infusion. One hour before the first feeding, an infusion of p-amino hippurate (PAH) was made and continued throughout the experimental period.
