| Due to the many effects of dietary nucleotide such as increasing the immune system, reducing stress, disease resistance, better growth and longer survival, the present study was designed and performed to investigate the effect of dietary nucleotide supplementation (ascogen) on hematological parameters and carcass composition of Siberian sturgeon (Acipenser baerii). Ascogen has optimal levels of RNA and nucleotides. In this regard, 450 fish (39.77 ± 10.24 g) were distributed in 15 tanks (300 liters). Fish were fed with 5 nucleotide treatments including control treatment (0 g/kg), treatment 1 (0.2 g/kg), treatment 2 (0.4 g/kg), treatment 3 (0.6 g/kg) and treatment 4 (0.8 g/kg) was selected in 3 replications for 63 days. Fish were fed about 3% of body weight in 4 meals. At the end of the period, it was determined that the fish were fed with treatments 3 (0.6 g/kg) and 4 (0.8 g/kg) in terms of hematological indices and treatment 4 (0.8 g/kg) in terms of carcass composition had better performance than other treatments. Therefore, treatments 3 (0.6 g/kg) and 4 (0.8 g/kg), especially treatment 4 (0.8 g/kg) had the most positive effect and nucleotides were able to induce their positive effects in fish and improved conditions and increased efficiency. |
