Effects of Echinacea purpurea and Allium sativum powdered extracts on growth indices, survival rate and liver enzymes in farmed Huso huso

Abstract

This study was performed to evaluate the effects of two types of powdered extract Echinacea purpurea and Allium sativum on growth indices and survival rate of Huso huso during a two-month period. For this purpose, 210 juvenile with an average weight of 27.74 ± 0.26 g were randomly placed in 21 half-ton fiberglass tanks in seven different treatments with three replications, including a control group and three experimental groups of different amounts of E. purpurea powder extract (T1, T2 and T3: 250, 500 and 1000 mg kg-1) and three experimental groups of different amounts of garlic powder extract (T4, T5 and T6: 250, 500 and 1000 mg kg-1). At the end of the experiment, a statistically significant difference was observed between the treatments in the mean final weight, mean final length, final biomass, final production, fish weight gain, mean daily growth, body weight gain increase, specific growth rate and daily growth rate (p0.05). The results showed that addition of 1000 mg turmeric powder extract per kg of food is more effective in improving growth indices.
