A comparative study of feed protein solubility in vitro under conditions of different origin: wheat, corn, soya, sunflower meal, gluten and seeds of galega, leaves of galega, galega’s hay that was harvested in the budding phase — beginning of flowering. It has established a significant influence on the type of feed grade protein solubility. According to research conducted found that the solubility of the studied protein feed is in the range from 7.4 % to 69.0 %. The highest solubility of the protein in sunflower meal was 69.0 %, the lowest rate found in the study of gluten 7.4%. The index of protein solubility of galega seed is 50.0 % in leaves of galega — 40.0 %, part — 37.0 % of its total. The research results indicate that relates to gluten feed with low solubility, protein Galega orientalis (La) — with medium and soybean and sunflower meal — with a high degree of solubility of protein. It has found qualitative assessment of the content of biologically active substances in plant organs Galega orientalis (La). There are the highest content of flavonoids and saponins in rosette leaves and ascorbic acid in the organs of plants and petals. The high content of tannins found in the petals of Galega orientalis (La). In the roots of the plants studied contained a high content of water-soluble coumarins and polysaccharides. Phytochemical studies of the plant Galega orientalis (La) indicates the absence in it of cardiac glycosides and antrahlikozydiv. Prospects of further research this issue.
