Data are presented as mean ± SEM (n = 5). EAA = essential amino acids; NEAA = non-essential amino acids; SEM = standard error of means; TAA = total amino acids.

¹I, control group (18% CP); II, group of 15.0% CP + 0.6% calcium pyruvate; III, group of 13.5% CP + 1.8% calcium pyruvate.

^a–cValues within a row with different superscripts differ significantly (P < 0.05).
