Effects of dietary BAO supplementation on jejunal antioxidant capacity and Nrf2 pathway in weaned pigs challenged with LPS. A–E The activities of MDA, T-AOC, SOD, GSH and GSH-Px. F–H The protein expression of P-Nrf2/Nrf2 and KEAP1. I–L The mRNA expression of HO-1, NQO-1, SOD and GSH-Px. Dates are presented as means ± SEM (n = 3 for protein expression; n = 5 for others). ^*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
