Copper levels and sources on mRNA expression of MDH gene in broiler liver. By the grouped means of the factors (Cu Level vs Source): (A) Cu levels in mg/kg of the grouping of sources (INO and ORG), (B) Sources of grouping of Cu levels. Mean values without equal letters (a-b) differ between groups (P < 0.05). MDH Malate dehydrogenase, INO Source inorganic trace minerals, ORG Source of organic trace minerals
