Effect of curcumin and ginger extract on growth and biochemical indices in rainbow trout (Oncorhynchus mykiss)

In this experiment, the effect of curcumin and ginger hydroalcoholic extract on growth performance and biochemical indicators of blood in rainbow trout (Oncorhynchus mykiss) were examined separately and in combination. The experiment was designed in a completely randomized design with zero levels (control), 0.5% ginger hydroalcoholic extract, 0.5% curcumin and 0.5% curcumin composition + 0.5% ginger hydroalcoholic extract in 4 treatments with 3 repetitions and Run for 8 weeks. At the end of expriment, fish blood serum was used to evaluate biochemical factors. The results showed that growth indices improved in treatments containing ginger hydrochloric acid extract and curcumin compared to the control group and had a significant difference (P <0.05). Current singular have shown that incorporating concentrations of curcumin and ginger individually and in combination significantly increases salmon growth and feed intake, but the best performance in the group containing ginger and curcumin extracts was observed in blood biochemical indicators. There was no difference between glucose, alkaline phosphatase (ALP) and blood cholesterol in fish fed a control diet and diets fed different levels of curcumin and ginger extract and a combined diet (P <0.05). There was a significant difference in the amount of blood triglycerides and total protein in the control of control and treatment containing ginger extract compared to other treatments (P <0.05). Overall, the concentrations of curcumin and ginger individually and in combination improved growth and biochemical properties in rainbow trout.
