Four iso-protein and iso-energy diets were prepared by using different dietary levels of U. dioica i.e., 0.5 g (T1), 0.75 g (T2), and 1.0 g/kg (T3) respectively, and the treatment TC (control) consist of the basal diet with 0% of U. dioica. The phytochemical analyses of U. dioica revealed the presence of flavonoids (25.39 μg/mL), alkaloids (30.21 μg/mL), tannin (2.97 μg/mL), terpenoid (6.15 μg/mL), glycosides (10.12 μg/mL), phenolic (25.16 μg/mL) and saponin was absent. The best result of growth parameters such as net weight gain (415±0.55 g), net length gain (4.20±0.04 cm), weight gain percent (85.65±0.40%), specific growth rate (0.30±0.01%), gross conversion efficiency (0.229±0.01%), feed conversion ratio (4.37±0.13) and condition factor (1.53±0.01) were recorded in treatment T3 in comparison with the other treatments. No mortality was observed in all the treatments resulting in a 100% survival rate. The haematological parameters (like haemoglobin level, total erythrocyte count, total leukocyte count, etc.) and serum biochemical parameters (including total serum protein, albumin, and globulin) showed better results in treatment T3.
