Results of species peculiarities of lipid metabolism in turkeys and geese study are presented in article. It was established that total lipids content in liver of turkeys was 1,9 times higher than such of geese and was almost same in egg yolks of both species. In composition of liver total lipids of turkey relative and absolute content of mono- and diacylglycerols, free cholesterol and absolute content of phospholipids, unesterified fatty acids and triacylglicerols was greater than in geese. In egg yolk of turkeys, as compared with geese, was observed higher level of free cholesterol, triacylglicerols and cholesterol ethers and less content of phospholipids and mono- and diacylglicerols. Study of lipid peroxidation products content was shown the increasing level of lipid hydroperoxides and TBA-reactive substances in liver and only TBA-reactive substances in egg yolk of turkeys, as compared with geese.
