Dietary organic acid supplementation improved productive performance, jejunal morphology, immune status, antioxidant- and inflammation-related gene expression, blood biochemistry, and meat quality of broiler chickens

Abstract

Highlights • Organic acid blend (OAB) improved finisher growth and feed efficiency.• OAB increased jejunal villus height and villus surface area.• OAB upregulated NFE2L2 and SOD1 and reduced TNFα expression.• OAB increased serum glucose, total protein, and albumin levels.• OAB improved meat quality by reducing water losses and increasing pH.
