The article provides the results of research on the amount of total lipid and phospholipid in blood serum and liver of pedigree hens of breed Shaver-579 at a period of intensive eggs laying. A direct interdependence of the total lipid and phospholipid amount in blood and liver of hens and the amount of vitamin A that has been spent in feeding, which points out a tight correlation of this vitamin’s amount in blood with the processes of metabolism of lipid and phospholipid in tissue, is established. Increasing of the unsaturated fatty acids level in total lipids amount of the liver of experimental hens along with the simultaneous decreasing of saturated fatty acids level has been noted.
