摘要

Jackfruit (Artocarpus heterophyllus) seeds represent a sustainable functional feed resource enriched with high-quality nutrients and bioactive phytochemicals including phenolic acids, flavonoids, and stilbenes. The present study assessed the efficacy of dietary jackfruit seed extract (JSE) on growth performance, hematological indices, lipid metabolism, and antioxidant status of Anabas testudineus over a 90-day feeding trial. Four experimental diets were formulated to contain 00 (control), 5, 10, and 20 g JSE/kg diet. Growth performance parameters including weight gain (WG), average daily gain (ADG), specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency (FE), and protein efficiency ratio (PER) were evaluated alongside hematological indices, serum biochemical markers, lipid profile, and oxidative stress biomarkers such as Superoxide Dismutase (SOD), Catalase (CAT), reduced Glutathione (GSH), Malondialdehyde (MDA), and Conjugated Dienes (CD). Dietary supplementation with JSE significantly (P < 0.05) improved growth performance, with fish fed 20 g/ kg exhibiting the highest Weight Gain (WG) (6.1 ± 0.02), Average Daily growth rate (ADG) (0.11 ± 0.008), Specific Growth Rate (SGR) (0.14 ± 0.004), and Protein Efficiency Ratio (PER) (1.5 ± 0.06), accompanied by improved Feed utilization Efficiency (FE) (50 ± 6.05). Hematological parameters were significantly elevated in 10 g/kg and 20 g/kg JSE-fed groups, whereas serum aspartate aminotransferase (AST) (79.8 ± 4.8 and 79 ± 5.2) and alanine aminotransferase (ALT) (22.1 ± 4.2 and 22.3 ± 3.3) activities were reduced, indicating improved hepatic function. Lipid metabolism was favorably regulated, as evidenced by decreased Total Cholesterol (TC) (248 ± 19.3), Triglycerides (TG) triglycerides (156 ± 9.6), Low-Density Lipoprotein (LDL) (94.6 ± 7.5), and Very-Low-Density Lipoprotein (VLDL) (24 ± 4.9), along with increased High-Density Lipoprotein (HDL) (126 ± 6.2) levels. Furthermore, antioxidant capacity was markedly enhanced, reflected by elevated Protein Content, SOD, CAT and GSH activities, and reduced MDA and CD concentrations. According to second-order polynomial regression analysis of growth parameters against dietary JSE levels, fish performed best at a dietary JSE level of 17.65 g/kg. Collectively, these findings demonstrate that dietary JSE exerts significant growth-promoting, hepatoprotective effects, and effectively mitigates oxidative stress in the experimental fish.
