Aims: The objective of this research was to investigate the effects of three commercial prebiotics A-Max, Celmanax and Ultra (each of 0.5, 1 and 1.5 g/kg diets) on growth, feed performance and blood biochemical compounds of beluga juvenile.
Materials & Methods: 900 fish with average weight of 21.5± 0.89 gr feeding was performed in 9 treatments (which on with three replicate) for 60 days. Control treatment was without supplementation. Fish were fed to satiation triple daily of 5% body weight. At the end of this period, the feed and growth performance were measured.
Findings: There was a significantly higher final body weight in ultra 0.5 (90.00± 21.78 g) compared with control (37.50± 9.60 g). The highest and lowest of food conversion were in treatments control and ultra (0.5), respectively. The results showed that the highest Fat and protein efficiency ratio was obtained in Ultra 0.5 (2.19± 0.77 and 7.37± 2.60) and lowest in control. Generally, the best treatments were in groups: Celmanax (dose of 0.5), A-Max (dose of 1.5) and Ultra (0.5). In addition, after determining the proper dose, blood samples were collected fish in the above-mentioned treatments. Based on the results of blood biochemistry parameters, there were no significant difference AST, ALP and ALT activity, so that the highest amount was obtained in the control. There were no significant differences in protein and cortisol experiment groups.
Conclusion: The results showed that the use of prebiotics in juvenile sturgeon diet has positive effects on feed performance and blood biochemical parameters.
