Effect of dietary Syzygium cumini on growth, immunological responses, and resistance against Aeromonas hydrophila infection in Pangasianodon hypophthalmus fingerlings (Sauvage, 1878)

), protein efficiency ratio (2.47 ± 0.06), and feed conversion ratio (1.34 ± 0.03) (P < 0.05). Pre-challenge, the haematological, biochemical, immune, and antioxidant parameters improved significantly in 1% JLM-fed group (P < 0.05). Post-challenge, the stress biomarkers, namely glucose, cholesterol, and triglycerides, and hepatic enzymes were significantly elevated (P < 0.05) in the control group compared to the JLM-fed groups. Furthermore, the cumulative survival was significantly higher in the 1% JLM-fed group (87.67 ± 5.7%) than in the control group (P < 0.05). In conclusion, dietary administration of JLM at 1% inclusion level enhances growth and health performance in P. hypophthalmus and is a potential feed supplement.
