Cu = copper; Fe = iron; Mn = manganese; Mn-MHAC = manganese methionine hydroxy analog chelated; TFRC = transferrin receptor; TF = transferrin; FPN1 = ferroportin 1; DMT1 = divalent metal transporter 1; CUTC = cutC copper transporter; CTR2 = Cu transporter-2; CTR1 = Cu transporter-1.

^{a, b} Values in the same row with different superscript are significantly different (P < 0.05) by one-way ANOVA.

Data are means of 6 replicates of 12 broilers per dietary treatment.
