Copper levels and sources on mRNA expression of LPL gene in the broiler liver. By the unfolding of the interaction Cu levels vs sources: (A) Cu levels in mg/kg within the INO and ORG source, (B) Sources within each Cu level in mg/kg. Mean values without equal letters (a-b) differ between groups (P < 0.05). LPL Lipoprotein lipase, INO Source of inorganic trace minerals, ORG Source of organic trace minerals
