Abstract

The increase of the level of fat-soluble vitamins in the diet of fish, and, first of all, vitamins E and A, with a pronounced antioxidant effect, is a necessary condition for elevation of their resistance and reproductive function. The same concerns the trace elements, especially selenium and zinc, with pronounced antioxidant effects, which are part of the active centers of antioxidant enzymes such as superoxide dismutase and glutathione peroxidase. As a result of our previous researches, the positive effect of supplements of fat-soluble vitamins and trace elements in the diet of carp females was found on their reproductive function, antioxidant and immune status of the organism, on the resistance and growth rate of their offspring. In this regard, the development of a biologically-active supplement to the diet of carp females based on vitamins and trace elements in the pre-spawning period is relevant in the scientific and production prospective. Thus, the purpose of our research was to study the effect of different amounts of vitamins A, D3, E and trace elements selenium, zinc and iodine on the reproductive capacity of female carp and on lipid metabolism in their eggs and this year young.

A comparative study of the effect of two different amounts of vitamins and trace elements as a supplement to carps in the pre-spawning period on indicators was conducted in the aquarium conditions. The highest fertility rates were observed in the fish of the first experimental group who received a supplement containing 2500 IU of Vitamin A as well as 5 mg / kg of potassium iodide, 40 mg / kg of zinc sulfate and 0.3 mg / kg of sodium selenite. Feeding at pre-spawning period to females carp with vitamin-mineral supplement containing Trivit in the amount of 5000 IU of vitamin A, as well as 10 mg / kg of potassium iodide, 60 mg / kg of zinc sulphate and 0.5 mg / kg of sodium selenite led to the increase in the content of total lipids in their eggs. As a result, we propose to develop a vitamin-mineral supplement for female carp on the basis of the following compounds tested: Trivitis in the amount of 2500 IU of vitamin A, 5 mg / kg of potassium iodide, 40 mg / kg of zinc sulfate, 0.3 mg / kg of sodium selenite.
