CON = basal diet; FMF = fermented mixed feed; EAA = essential amino acids; NEAA = non-essential amino acids; FAA = flavor amino acids.

^a,b Within a row, values with different superscripts differ significantly at P < 0.05. Data are expressed as means and SEM, n = 6.

¹FAA = glutamate + aspartate + alanine + arginine + glycine.
