Values are expressed as mean ± SD (n = 6). Figures in the same column with different lowercase letters indicate significant differences among dietary treatments (). VH, villus height; VD, villus diameter; EH, enterocyte height; and LT, lamina propria thickness. Dietary codes: CT, control diet without phytase and microalgae; 500F, diet containing 500 FTU; 1,000F, diet containing 1,000 FTU; 2,000F, diet containing 2,000 FTU; and 10,000F, diet containing 10,000 FTU.
