The duodenal (A), jejunal (B) and ileal (C) mRNA expressions of fetal amino acid and peptide transporters in CON, RES, RES + ARG and RES + NCG groups on d 110 of gestation. Results are expressed as means ± SEM (n = 16 per group). CON, animals raised with 100% of nutrient requirements recommended by NRC (2007); RES, 50% of nutrient requirements recommended by NRC (2007); RES + ARG, 50% of nutrient requirements recommended by NRC (2007) and 20 g/d RP-Arg; RES + NCG, 50% of nutrient requirements recommended by NRC (2007) and 5 g/d NCG. a, b, c Means labeled with different letters indicate statistical significance (P < 0.05). SLC7A1 = solute carrier family 7 (cationic amino acid transporter, y+ system), member 1; SLC1A1 = solute carrier family 1 (neuronal/epithelial high-affinity glutamate transporter, system XAG), member 1; SLC7A7 = solute carrier family 7 (amino acid transporter light chain, y+ L system), member 7; SLC1A5 = solute carrier family 1 (alanine-serine-cysteine amino acid transporter 2), member 5; SLC15A1 = solute carrier family 15 (peptide transporter 1), member 1.
