Effects of dietary quercetin supplementation on the relative mRNA expression of immune response-related genes in jejunum (a-j) and ileum mucosa (k-t) of LPS-challenged laying hens. CON, laying hens fed with basal diet; LC, laying hens fed with basal diet and challenged with LPS; LQ, laying hens fed with quercetin-supplemented diet and challenged with LPS. Values are presented as mean ± SEM (n = 8). ^a-b means with different lowercase superscripts represent significant difference (P < 0.05).
