[The dynamics of the secretion of linoleic acid as a component of the lipid classes with milk and their metabolism in the body of cows].

The paper is devoted to the questions of metabolism of the lipid classes and essential fatty acids in the ruminant organism and secretion of those acids with milk. The lipid classes, such as triacylglyceroles, phospholipides and cholesterol ethers, containing linoleic acid and others acids of that family, their function, structure, quantity and transport in the organism are characterized. The physiological lactation standards (duration, breed, season and diurnal variations) are described more exactly.
