Data are presented as means with SD. Kynurenine and kynurenic acid concentrations in A liver, B colon, C serum, and D muscle. The mRNA expressions of E indoleamine 2,3-dioxygenase 1 (IDO1), F kynurenine aminotransferase1 (KYAT1), G KYAT2, H KYAT3, I KYAT4, J protein kinase AMP-activated catalytic subunit alpha 1 (AMPK), and K peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) in the muscle. Different lowercase letters on bars indicate significant differences among pig breeds (P < 0.05, Tukey’s post hoc test). TB, Taoyuan black; XB, Xiangcun black.
