This study aimed to evaluate the effect of additives used in tilapia feed and represented by TechnoMos® prebiotic (Saccharomyces cerevisiae) and BetaPlus® probiotic (Bacillus subtilis and Bacillus licheniformis) on the growth and biochemical composition of biological material. The analysis of the results obtained on the principal growth indicators shows a positive correlation between the applied feeding regime and the biomass gain. In the first experimental stage, there was an upward trend of biomass gain depending on the feeding regime applied, obtaining values between 1439 ± 18.29 g in the control variant (V0) and 1774.61 ± 47.65 g in the experimental variant with synbiotic (V3). In the second experimental stage, the biomass gain obtained varied from 3286 ± 15.05 g in the control variant to 4078.52 ± 69.84 g in the synbiotic variant. Biochemical analysis of tilapia muscle tissue showed an increase in the content of proteins, lipids in biomass of the samples fed with the probiotic Betaplus® correlated with the increase in biomass weight, compared to the control variant. In conclusion, the analysis of growth indicators shows the beneficial effect of symbiotic variant through their synergistic action and the influence of probiotic applied on improving biomass gain and biochemical composition.
