doi: 10.1016/j.aninu.2026.01.006

Figure Lengend Snippet: Effects of Trp supplementation in low-protein diets on the relative gene expression in the jejunum of suckling piglets. Genes related to the (A) intestinal immune barrier, (B) intestinal physical barrier, (C) chemical barrier, and (D) antioxidant functions in the jejunum of piglets. Data are expressed as mean and SEM ( n = 8). Groups marked with different letters differ significantly at P < 0.05. CON, normal protein control group; LP + 0.21% Trp, low protein supplemented with 0.21% SID Trp group; LP + 0.39% Trp, Low protein supplemented with 0.39% SID Trp group. SEM = standard error of the mean; SID = standardized ileal digestible; Trp = tryptophan.

Article Snippet: The serum total antioxidant capacity (T-AOC; A015-2-1), the activities of total superoxide dismutase (T-SOD; A001-3-2), catalase (CAT; A007-1-1), and glutathione peroxidase (GSH-Px; A005-1-2), as well as the malondialdehyde (MDA; A003-1-2) content were measured using the corresponding commercial kits (Nanjing Jiancheng Bioengineering Institute, Nanjing, Jiangsu, China), following the manufacturer's instructions.
