Effects of dietary supplementation with essential oil on the relative mRNA expression of genes. a and b were results of relative mRNA expression of genes related to tight junction proteins and immune response, respectively. Data are expressed as means ± standard deviation. a-c Treatments with no common superscripts differ significantly (p < 0.05). Control, hens received a basal diet; EO100, EO200 and EO400, hens received a basal diet supplemented with 100, 200 or 400 mg/kg oregano essential oil, respectively. L and Q represent the linear and quadratic effects of dietary essential oil supplementation dose assessed by regression analysis.
