Abstract :
Abstract[1] The present research was conducted with the purpose of evaluating the effect of protexin probiotic commercial product on some growth parameters and body compositions of the Siberian sturgeon for 8 weeks. The experiment was performed using one control treatment and three experimental treatments with three replications. This commercial product was used at three levels of 0.5, 1 and 1.5 g/kg diet. The fishes were fed three times a day with 8-hour intervals. The results showed that this probiotic product had not statistical significant differences on feed parameters such as food conversion ratio (FCR), specific growth rate (SGR), body weight increase index (BWI) and condition factor (K) (p >0.05). The results was shown statistical significant differences on crude protein and lipid levels in the fish carcass (p <0.05). The highest crude protein levels were observed in experimental treatments 1 and 2 which had significant statistical differences with those of the control treatment and treatment 3 (p <0.05). The highest crude lipid levels were observed in the control treatment and treatment 3 and had significant statistical differences with those of experimental treatments 1 and 2 (p <0.05). This experiment revealed that protexin probiotic product did not have any statistical significant differences on the growth parameters of the Siberian sturgeon, but increased nutrition levels in the fish carcass which could be valuable for fish farmer in terms of improving the quality of its meat. *- Corresponding Authors; Email: kathy.mahmoudi@gmail.com
