Fig. 12From: Broiler responses to copper levels and sources: growth, tissue mineral content, antioxidant status and mRNA expression of genes involved in lipid and protein metabolismCopper levels and sources on mRNA expression of CTR1 gene in broiler intestine. By the unfolding of the interaction Cu level vs source: (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). CTR1 Copper conveyor 1, INO Source of inorganic trace minerals, ORG Source of organic trace mineralsBack to article page
