Effect of dietary xylan on immune response, tight junction protein expression and bacterial community in the intestine of juvenile turbot (Scophthalmus maximus L.)

The present study investigated the effects of dietary xylan on intestinal barrier function and bacteria community of turbot (Scophthalmus maximus L.). A 12-week feeding trial was conducted using three isonitrogenous and isolipidic diets containing 0%, 1.25% and 5% xylan, respectively. Dietary xylan at 1.25% significantly increased the gene expression of transforming growth factor β and tight junction protein Tricellulin, and decreased the...
