Effects of dietary valine to lysine ratio during late gestation on regulation of valine metabolic enzymes. LV: total valine: lysine = 0.63: 1; MV: total valine: lysine = 0.73: 1; HV: total valine: lysine = 0.93: 1. a, b shows the relative protein expression of BCAT and BCKDH in mammary tissue of gilts at day 1 of lactation, n = 4. c, d shows the relative protein expression of BCAT and BCKDH in mammary tissue of gilts at day 21 of lactation, n = 4. BCAT: branched-chain aminotransferase; BCKDH: branched-chain α-keto acid dehydrogenase. All data with error bars represent the mean ± SEM. P¹ = linear, P² = quadratic. Means not sharing the same letter are different (P < 0.05)
