Abstract

This research examined the impact of incorporating cinnamon meal (CM), water cinnamon extract (CEX), and its combination on fish productivities, blood parameters and economic outcomes over 56 days. Five groups of fish were fed different diets: a control diet (D1), 1% cinnamon meal (D2), 1% water cinnamon extract (D3), combinations of 0.5% CM and 0.5% WCEX (D4), and 1% CM and 1% WCEX (D5). All diets were iso-caloric and iso-nitrogenous. Significant improvements in growth performances and feed utilization parameters were observed (P<0.05) in D5 (1% CM and 1% WCEX) compared to control or other treatments, with 100% survival in the D2, D4, and D5 groups, compared to 93.33% in D1 and D3. Feed conversion ratio improved with cinnamon-treated diets, and serum protein and globulin levels increased significantly, while cholesterol levels decreased. Body composition analysis showed a significant reduction in OM and CP, while DM, EE, ash, and GE content increased. The economic return improved in cinnamon-treated groups, though the percentage of profitable value decreased slightly. Diet costs were reduced, and net improvement over the control ranged from 2.32 to 8.82%. In conclusion, adding cinnamon meal and/or cinnamon water extract to fish diets impacted growth and feed efficiency positively, without negative effects.
