Study of protein solubility in feed of different origins and content of biologically active substances in vitro
Journal Title: Біологія тварин - Year 2014, Vol 16, Issue 3
Abstract
A comparative study protein solubility of feed of different origin: wheat, corn, soya, sunflower meal, gluten and seeds of galega, leaves of galega, galega’s hay harvested in the budding phase (beginning of flowering) has been conducted in vitro. We have established a significant influence on the type of feed grade protein solubility. According to research conducted it has been found that the solubility of the studied protein feed ranges between 7.4 % and 69.0 %. The highest solubility of the protein was in sunflower (69.0 %), the lowest rate was found in gluten (7.4 %). The index of protein solubility in galega seed is 50.0 %, in galega leaves — 40.0 %, in hay — 37.0 % of its total amount. The research results indicate that gluten belongs to feed with low protein solubility, Galega orientalis (La) belongs to feed with medium solubility of protein, soybean and sunflower meal has a high degree of protein solubility. A qualitative assessment of the content of biologically active substances in Galega orientalis (La) plant organs has been found. There is the highest content of flavonoids and saponins in rosette leaves and ascorbic acid in the organs of this plant and petals. The high content of tannins has been found in the petals of Galega orientalis (La). The roots of the studied plants contain high level of water-soluble coumarins and polysaccharides. Phytochemical studies of the plant Galega orientalis (La) indicate the absence in it of cardiac glycosides and antraglycosides. Prospects of further researches of this issue are highlighted.
