Effect of oral administration of Levamisole, Quil-A and Cinnamon in growth amount, hematological and immune parameters of Marmalade cichlid, Labeotrophus fuelleborni (Ahl, 1926)

The study evaluated the effects of Levamisole, Quil-A and Cinnamon on growth, hematological and immune parameters of marmalade cichlid. Fish (2.00 ± 0.02 g) were fed diets supplemented with 0.2% Levamisole, 0.5% Quil-A and 1% Cinnamon for 60 days and the control group was fed with basal diet. The highest weight gain and condition factor were observed in fish fed diet enriched with Levamisole followed by Quil-A. There was no significant difference between the three treatments in specific growth rate (SGR) (p>0.05). However, the SGR showed a significant difference in the control group (2.16 ± 0.02% day-1) compared to other treatments (p<0.05). No significant difference in survival rate was observed between treatments (p>0.05). The lowest FCR was recorded in fish fed diet enriched with Levamisole (1.74 ± 0.95). The highest levels of RBCs, hemoglobin and hematocrit were observed in Levamisole treatment, but the highest number of WBCs was recorded in Cinnamon treatment (16766700 ± 450.92 mL-1). The maximum level of lysozyme was also observed in Cinnamon treatment (8.84 ± 0.38 µg mL-1). While no significant difference was recorded in the levels of the basophil, eosinophil, and monocyte, the highest levels of neutrophils (25.00 ± 1.0%) and lymphocytes (78.33 ± 0.57%) were observed in Cinnamon treatment. So, the use of Levamisole significantly improved growth performance and hematological parameters, but immunological parameters were improved with fish fed diet supplemented with Cinnamon.
