Abstract :This research was carried out to determine that the effects of diets containing 30% hazelnut meal and different proportions of phytase enzymes on the growth performance of Siberian sturgeon insert ignore into journalissuearticles values(Acipenser baerii); insert ignore into journalissuearticles values(initial mean weight, 960.23 ± 0.55 g);. The trial diets consisted of feeds supplemented with 0.25 g kg-1 insert ignore into journalissuearticles values(G2);, 0.50 g kg-1 insert ignore into journalissuearticles values(G3);, and 1.00 g kg-1 insert ignore into journalissuearticles values(G4); phytase enzyme, and with no enzyme added to the control group insert ignore into journalissuearticles values(G1);, respectively. Experiment groups were performed in 3 replicates and trials were carried out for 90 days. As a result, adding phytase enzyme to feeds contain 30% hazelnut meal was found to have a positive effect on the weight gain insert ignore into journalissuearticles values(WG, g);, the protein efficiency ratio insert ignore into journalissuearticles values(PER);, feed conversion ratio insert ignore into journalissuearticles values(FCR);, and specific growth rate insert ignore into journalissuearticles values(SGR, %);. Growth performance was found to be more successful in all groups fed feeds supplemented with phytase enzyme compared to the G1 group insert ignore into journalissuearticles values(P<0.05);. The G4 was the best group than the others statistically insert ignore into journalissuearticles values(P<0.05);. In terms of the digestibility effect of enzyme added groups, the highest total digestion rate insert ignore into journalissuearticles values(77.14 ± 0.07%); was obtained in the G4 enzyme group and the lowest total digestibility insert ignore into journalissuearticles values(74.32 ± 0.02%); was estimated in the G1.
