Effects of EO + OA on the intestinal integrity of weaned piglets. (A-D) Protein levels of ZO-1, occludin and claudin-1 in the jejunum (n = 3 replicates per group); (E) Relative mRNA expression levels of ZO-1, ccludino and laudinc-1 in the jejunum (n = 6 replicates per group). CON = piglets fed the basal diet with intraperitoneal saline injection; LPS = piglets fed the basal diet and injected intraperitoneally with lipopolysaccharide (LPS) to induce stress; EO + OA + LPS = piglets fed the basal diet supplemented with essential oils (EO) and organic acids (OA) and injected intraperitoneally with LPS to induce stress; ZO-1 = zonula occludens-1. ∗ means significant difference (P < 0.05).
