For this purpose, H. molitrix were distributed into six groups, namely T1, T2, T3, T4, T5, and T6. All treatments were assessed in triplicates. T1 was designated as the negative control treatment, receiving no Ni exposure or dietary supplementation, whereas T2 acted as the positive control treatment, exposed to sub-lethal concentrations of nickel chloride (NiCl<sub>2</sub>) at 3.6 mg/L. Groups T3-T6 received diets enriched with 1%, 2%, 3% and 4% P. nigrum extract, respectively and were also exposed to 3.6 mgL<sup>-1</sup> NiCl<sub>2</sub> toxicity. The findings of this investigation revealed that T2 exhibited decreased growth responses, characterized by a weight gain (WG) of 8.12 g, percentage weight gain (WG%) of 77.83% and specific growth rate (SGR) of 0.96. Additionally, T2 displayed altered hematological parameters such as reduced red blood cells (RBC: 1.3 × 10<sup>6</sup> mm<sup>-3</sup>) and hemoglobin levels (Hb: 5.8 g/100 ml), and increased white blood cell counts (WBC: 75.31 × 10<sup>3</sup> mm<sup>-3</sup>). Also, T2 showed reduced protein (13.14%), fat (2.15%), and moisture content (73.44%), hepatocyte degeneration, and Ni bioaccumulation in hepatic tissues. In contrast, T1 (control negative) and T3 (1% P. nigrum extract) demonstrated improved growth performance with WG of 18.49 g and 16.92 g, respectively.

Furthermore, liver histological analysis revealed that dietary supplementation with 1% P. nigrum extract (T3) effectively minimized the adverse effects of NiCl2 toxicity, characterized by a normal central vein structure and significantly reduced histological damage. In conclusion, the results show that 1% P. nigrum extract supplementation significantly ameliorates the adverse effects on carcass composition, elevates growth responses, enhances hematological indices, and mitigates the toxic effects of Ni on the histology of H. molitrix.
