A nitrogen balance and whole-body protein turnover experiment was conducted with 12 female pigs, 45 kg liveweight, given diets containing 5, 9 or 14% non-essential amino acids (NEAA) and 7% essential amino acids. Whole-body protein turnover was determined using the end product method after a single oral dose of 15N-glycine to a semisynthetic diet. Daily N intake was 1.45, 1.96 and 2,48 g/kg for the low, medium and high NEAA diets, respectively.
