Description:
Probiotics are widely used in modern aquaculture. The aims of this study were to investigate the effect
of probiotic bacteria of Bacillus subtilis strain on growth parameters of rainbow trout and to determine
the best application rate of this bacterium. The results of this research will be widely used in
improving the production of this valuable species and creating new perspectives in breeding
conditions and increasing its nutritional value. In this study, the effect of Bacillus subtilis IS02 in a
completely randomized design with four different treatments including: T_1 probiotic supplementationfree, T_2 containing 10^6
, T_3 with 10^7
and T_4 with 10^8 CFU/g of B. subtilis in diet for 30 days on some
growth parameters (WG, SGR, FCR, PER, LER, PPV, LPV, CF, VFI, FE, DGI) was investigated.
Data analysis was performed using one-way ANOVA and Bonferroni test. The results showed that T_4
treatment with a concentration of 10^7 CFU/g had a significant effect (p=0.001) on the increase of
protein value (PPV), but no significant effect was observed in other parameters of growth (p〉 0.05).
