Effect of dietary Zn source on the protein expression levels of Zn, amino acid, and small peptide transporters in the duodenum of broilers at 39 days of age. Values are means ± SE, (n = 7/8). Lacking the same letters (a and b) means significant differences, p < 0.05. ZnT1, zinc transporter 1; ZnT4, zinc transporter 4; ZnT5, zinc transporter 5; ZnT7, zinc transporter 7; ZnT9, zinc transporter 9; ZIP3, Zrt-irt-like protein 3; ZIP5, Zrt-irt-like protein 5; B0AT1, B-0-system neutral amino acid co-transporter; LAT1, L-type amino acid transporter 1; y + LAT2, y + L-type amino acid transporter 2; rBAT, b0,+-type amino acid transporter; PepT1, peptide-transporter 1; Zn-Prot M, Zn proteinate with moderate chelation strength (Qf = 51.6). The protein expression levels were calculated as the relative quantities (RQs) of the target gene protein to the β-tubulin protein.
