Study of the effectiveness of the use of bioflavonoids in the composition of production feeds on the sturgeon physiological state

Abstract

The appearance of new preparations with antioxidant properties allows us to improve the technology of fish feeding and increase the pro-oxidant-antioxidant balance. Due to the fact that an important criterion for choosing a feed additive is environmental safety, natural bioantiooxidants of flavonoid nature, in particular dihydroquercetin, isolated from larch wood, are of interest. It is known that dihydroquercetin has capillaroprotective, lymphokinetic and other properties, but it has a low solubility in water (about 1 g/l), which probably limits its pharmacological activity. In a recent study, it was found that the use of dihydroquercetin (DHA) in a composition with plant polysaccharides increases its pharmacological effect, which is associated with an increase in solubility. One of these commonly used polysaccharides is arabinogalactan, also isolated from larch. The scientific and practical significance of the work consists in testing the effectiveness of bioflavonoids in the composition of production feeds for sturgeon fish as sources of antioxidants, immunostimulants and prebiotics.

Potential Use of Fennel (Foeniculum Vulgare) as Fish Immunostimulant: Article Review

“…(2024) Based on the results of the literature study in Table 1, it is known that fennel plants contain various bioactive compounds, but the compounds that are always mentioned in all the literature are flavonoids. According to Ponomarev et al, (2021), flavonoids are low molecular weight substances that are often found in vascular plants. These compounds are found in all parts of plants, especially in photosynthetic cells and have a wide spectrum of action as antioxidants, enzymatic inhibitors, precursors of toxic substances, protection against ultraviolet radiation, and also participate in energy conversion.…”

Feed additive for fishdiet with antioxidant and immunostimulating effect

“…In recent years, much attention has been paid to the use of natural food additives in aquaculture. Studies on the effect of certain antioxidants in the enrichment of fish diets are conducted by both foreign and domestic scientists [4][5][6][7][8][9][10]. At the same time, there is a positive effect on productivity, metabolic processes of fish and the immune status of fish.…”
