Improving Yellow Mealworm (Tenebrio molitor) Utilization with Sodium Butyrate in Nile Tilapia Diets: Effects on Growth Performance, Intestinal Histology, Antioxidative Response, and Blood Biomarkers

Figure 2

Histomicrograph showing the histological structure of the liver 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 hepatic (H) and pancreatic (black arrow) structures in all groups appeared normal without deterioration or vacuolation. However, the cosupplementation with T. molitor/sodium butyrate stimulated an apparent glycogen deposition within the hepatocytes (d). Stain H&E. Bar 100 µm.
