Abstract: (1662 Views) |
In this study, the effect of Ethylenediaminetetraacetic acid (EDTA) was evaluated on growth performance and body composition in beluga (Huso huso) juveniles. For this purpose, a total of 225 beluga juveniles with initial weight 38.47 ± 0.58 gr (Mean ± Standard Division) were fed with five treatments with three replications including 0 g/kg EDTA (Control, C), 5 g/kg EDTA (EDTA 5), 10 g/kg EDTA (EDTA 10), 15 g/kg EDTA (EDTA 15), and 20 g/kg EDTA (EDTA 20) for 8 weeks. At the end of the feeding trial, growth performance and body composition were investigated. The results showed that EDTA different levels have a significant effect on final weight, weight gain, and specific growth rate (p < 0.05). The highest final weight, weight gain, and specific growth rate were observed in EDTA10 and EDTA15 treatments. The lowest final weight, weight gain, and specific growth rate obtained in the control group. The results of body composition analysis at the end of the feeding trial showed that no significant difference was observed in protein, ash, moisture, lipid, and dray mater between treatments (p > 0.05). The present study showed that feeding fish with the 15 gr/ kg diet EDTA improved growth and health.
