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; VH = villi height; CD = crypt depth.
a-c Means with different letter superscripts indicate significant differences (P＜0.05), while with no letter or the same letter superscripts indicate no significant differences (P＞0.05).
