Effects of dietary BAO supplementation on intestinal morphology in weaned pigs challenged with LPS. A Duodenal morphology, villus height, crypt depth, ratio of villus height to crypt depth. B Jejunal morphology, villus height, crypt depth, ratio of villus height to crypt depth. C Ileal morphology, villus height, crypt depth, ratio of villus height to crypt depth. Dates are presented as means ± SEM (n = 5). ^*P < 0.05; ^**P < 0.01. CON, corn-soybean meal basal diets group treated with saline; LPS, corn-soybean meal basal diets group treated with lipopolysaccharide; BAO + LPS, corn-soybean meal basal diets + 5 kg/t benzoic acid + 500 g/t essential oils group treated with lipopolysaccharide
