Copper levels and sources on mRNA expression of GSK-3β gene in broiler breast muscle. By the unfolding of the source vs copper level interaction: (A) Cu levels in mg/kg diet within the INO and ORG sources, (B) Sources within each Cu level. Mean values without equal letters (a-b) differ between groups (P < 0.05). GSK-3β, glycogen synthase kinase 3β; INO, inorganic trace minerals; ORG, organic trace minerals
