The research has followed the effects of the feeding bio-additives Actigen, SelPlex and Yea-Sacc-1026 on the quality of the Siberian sturgeon (Acipenser baerii) meat. The experiments were carried out on a number of 108 Siberian sturgeons distributed in four groups, each with 27 individuals per group. In the experimental group 1 (1E), probiotic Actigen was added 0.08% to the fodder in the combined fodder, 0.03% organic selenium (SelPlex) was added to the experimental group 2 (2E), and to the third experimental group (3E) probiotic Yea-Sacc-1026 in proportion of 0.2% was added. The experimental period lasted 68 weeks, from 1st of July 2016 to 2nd of November 2017. At the end of the experiment control slaughters were made, 5 sturgeons from each group, the meat quality being determined but also its chemical composition. In terms of slaughter yield, equal values have been found between the experimental and control groups, the differences being not statistically represented. The administration of bio-additives (Actigen, SelPlex and Yea-Sacc 1026) resulted in a decrease in water content in experimental groups, 1E (Actigen) 28.71%, 2E (SelPlex) 26.39% and 3E (Yea-Sacc 1026), while the control (C) has 31.20%. The average percentage of crude protein of the 3E (47.31%) increased by 11% compared to the control group (36.29%) and by 6.5% compared to the experimental groups 1E and 2E. The highest gross fat value was observed in 2E group (31.75%) exceeding the control group score (30.27%), while the 3E group has shown the lowest value (23.3%) followed by experimental group 1E with 26.33%. The crude ash content did not show statistically represented differences between the experimental groups and the control group.
