Species peculiarities of lipid and fatty acid composition of liver and egg yolk in Japanese quails and laying hens have been studied. In results of our study was determined that total lipids content in liver of Japanese quails and laying hens was almost same, but in egg yolk less by 20,96 %.It was established less level of phospholipides, mono- and diacylglycerols and higher content of triacylglycerols in total lipids composition in liver of Japanese quails, as compared with liver of hens. In egg yolk of Japanese quails was observed higher triacylglicerols level and less free cholesterol content. It was established higher palmitic acid level among saturated fatty acids anh higher content of oleic and linolenic acids among unsaturated fatty acids in composition of liver total lipids of Japanese quails. In liver of laying hens was observed higher level of stearic, linoleic and arachidonic acids. It was shown higher relative content of saturated and polyunsaturated fatty acids in egg yolks lipids of Japanese quails. Oleic acid level was higher in egg yolk of laying hens.
