<i>In ovo</i> trace element supplementation enhances expression of growth genes in embryo and immune genes in post‐hatch broiler chickens

Abstract

In ovo supplementation of Zn, I and Se did not improve the post-hatch growth, but increased growth-related gene expression. Iodine improved humoral immune gene expression whereas Zn and Se enhanced cell-mediated immune gene expression in broiler chickens. © 2015 Society of Chemical Industry.
