Optimization of cultivation of hybrids of Russian and Siberian sturgeon when using the "Abiotonic" feed additive in the diet

Abstract

The results of the research work on feeding the biologically active additive "Abiotonic" showed that the best growth and development indicators were distinguished by sturgeons of the 2 experimental group, who received 1.0 ml of "Abiotonic" per 1 kg of live weight. The gross increase of one individual during the experiment in this group exceeded the control values by 6.96 %, the average daily increase by 7.1 %, and the relative increase by 9.53 %. Hybrids of the 2 experimental group exceeded the indicators of individuals from the control group in biological carcass length by 9.23 %, in head size by 5.58 %, carcass length by 11.79 %, tail stem length by 8.04 % and tail fin length by 8.56 %. Feeding the feed additive "Abiotonic" did not have a negative effect on the development of the internal organs of sturgeons, they did not have pathological changes in development. The costs of compound feed, crude protein and energy in the experimental groups receiving the feed additive "Abiotonic" with compound feed were 2.0 - 7.9 % lower than the control data.
