The The appropriateness of the use of soy isoflavone feed preparation in poultry farming for adjusting mineral metabolism

Abstract

Mineral substances take part in all metabolic processes of the poultry organism, are catalysts of metabolism; its productivity, quality and safety of poultry products, profitability and profitability of the industry depend on the efficiency of mineral metabolism. To activate osteogenesis, the choice of isoflavones is justified, since the wide spectrum of biological action of polyphenols allows for a systemic corrective effect on organs and systems, significantly increasing the nonspecific resistance of the body to endo- and exogenous factors. According to the developed technology, a feed prepara-tion of soy isoflavones EXSO was obtained, its effect on the main indicators of mineral metabolism in the body of laboratory animals was determined, and the prospects for its use in poultry farming were outlined. It was established that the chemical composition of EXSO is represented by a wide range of water-soluble substances: peptides, amino acids (32-38%), sugars (42-46%), vitamins, phenolic compounds, macro- and microelements, isoflavones genistein and daidzein. A significant number of proteolysis inhibitors in the prep-aration, which have anti-inflammatory properties, prebiotics (raffinose and stachyose), which eliminate the phenomenon of dysbiosis and allow you to use the potential of normobiota to enhance the osteobiotic effect. In vivo, it was established: the introduction of the preparation of soy isoflavones EXSO into the body increases the activity of alkaline phosphatase (a biochemical marker of osteoblasts) in the blood serum: starting from the 8th day of use, at a dose of 300 mg/g, and also on the 24th day at a dose of 150 mg/kg and by the end of the observation, the activity level is significantly higher than the corresponding indicators in the control group. The introduction of EXSO reduces the calcium content in the blood on the 14th day at a dose of 300 mg/kg and on the 34th day at a dose of 150 mg/kg, which indicates an intensive course of mineralization processes in the body. Daily administration of EXO significantly shortened the period of bone densification: at a dose of 150 mg/kg – 30 days earlier, and 300 mg/kg – 40 days earlier than in the control group. It is recommended to include EXSO feed preparation in poultry diets without increasing the calcium content in the feed.
