Figure 1

Histomicrograph showing the histological structure of the middle segment of Nile tilapia intestine in the fish meal (a), T. molitor (b), fish meal/sodium butyrate (c), and both T. molitor/sodium butyrate (d). The intestinal wall (IW) intestinal villi (IV) showed apparent growth, mainly in group (d), in addition to immune cell infiltration (black arrow) in groups (b) and (d). Stain H&E. Bar = 100 µm.
