Effects of dietary BAO supplementation on mRNA expressions of inflammation levels in jejunum of weaned pigs challenged with LPS. A–N The mRNA expression levels of TNF-α, IL-1β, IL-6, IL-12, TGF-β, PBD-1, PBD-2, PBD-3, PBD114, TLR4, MyD88, IKKα, IKKβ and IκB. 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
