Effect of β-glucanase and β-xylanase enzyme supplemented barley diets on nutrient digestibility, growth performance and expression of intestinal nutrient transporter genes in finisher pigs

•The agronomical conditions in which barley is grown affects its nutrient content.•These agronomical conditions also affected the feeding value of barley in pig diets.•Enzyme supplementation increased ADG and ADFI in low quality barley diets in pigs.•Enzyme supplementation increased nutrient digestibility of barley based diets.•Enzyme supplementation modified the expression of CD36, PEPT1 and SGLT1 gene.
