Fig. 2From: 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 mTOR gene in broiler breast muscle. By the pooled means of the factors (Cu Level and 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 source groups (P < 0.05). mTOR, mechanistic target of rapamycin; INO, source of inorganic trace minerals; ORG, source of organic trace mineralsBack to article page
