Abstract
A study of the feed additive “Faybramax Plus”, which is a metabiotic for the management of fish autoflora and comprehensive prevention of bacterial infections, was conducted on sterbel yearlings with an initial weight of
130 g. The experience takes place in swimming pools. The water supply in the pools was carried out from a well. The conditions of detention corresponded to the technology of fish farming. The duration of the experiment was 60 days. The number of fish in the group was 150. The control group 1 received a full-fledged combo feed; group 2 was given a full-fledged compound feed + 0.3% of the feed additive “Faybramax Plus”; Group 3 consumed full-fledged compound feed + 0.6% of the feed additive “Faybramax Plus”; group 4 was fed full-fledged compound feed + 1.0% of the feed additive “Faybramax Plus”. It was found that when using the studied feed additive, the live weight of fish in the experimental groups increased by 1.9–6.0% at the end of cultivation. The protein content in the body of sterbel was higher compared to the control by 1.8–7.5%. The cost of the resulting products (increase) compared with the control, it decreased by 4.87–13.78% per group. Profit when using the feed additive “Faybramax Plus” increased by
345.11–1,068.23 rubles per group. The level of profitability increased by 2.71–7.66% per group compared to the control. As a result of the conducted research, it was found that the use of the feed additive “Faybramax Plus” produced by the company SYMBIO is most effective in a percentage ratio of 0.6% by weight of feed, as a result of which the level of profitability increases by 7.66%.
