MDA: malondialdehyde; GSH: glutathione; MnSOD: superoxide dismutase. CON: broiler chickens fed a basal diet; BIS: broiler chickens fed a basal diet with 150 mg/kg bisdemethoxycurcumin; LPS: broiler chickens fed a basal diet with LPS injection; L-BIS: broiler chickens fed a basal diet with LPS injection and 150 mg/kg bisdemethoxycurcumin. Diet: 0 or 150 mg/kg bisdemethoxycurcumin treatment; Stress: saline or LPS challenge; D × S: interaction between bisdemethoxycurcumin treatment and LPS challenge. Data were expressed as means and SEM, n = 8 replicates per treatment and 10 birds per replication. Means within a row with no common superscript differ P < 0.05.
