Concentrations of free amino acids in longissimus dorsi homogenate sampled at the end of the phenylalanine kinetic study. A: Sum of N shuttles (Nshut = alanine, aspartate, glutamate), essential amino acids (EAA), nonessential amino acids (NEAA), and total amino acids (Total). B: Amino acids not oxidized within the muscle (NonOx = phenylalanine, histidine, methionine), branched-chain amino acids (BCAA = valine, isoleucine, leucine), and 3-methyl-histidine (3M-His). C: Ratio of essential to nonessential amino acids (EAA/NEAA). D: Individual essential amino acids. E: Individual nonessential amino acids. * Age effect with P < 0.05; † milk formula effect with P < 0.05 unless noted otherwise. Int represents interaction between age and milk formula (P < 0.05); n = 7 piglets per milk formula per age group for 28 observations.
