[Metabolism of linoleic acid given with the feed in the calf liver]

Calves were fed with the whole milk substitute containing different amounts of linoleic acid--0.70, 1.44 and 3.65 per cent from the total energy content of the ratio--for the 1st, 2nd and 3rd groups, respectively, beginning from the 2nd to the 60th day of life. The feeding of different amounts of linoleic acid has no significant effect on the lipid content and the ratio of different type of lipids as well as on prostaglandins E2 and F 2 alpha contents. The increase of linoleic acid quantity in the liver lipids of calves occurs parallel to that of its uptake. During the liver homogenates incubation in the medium containing [1-14C] linoleic acid 0.15-0.22 per cent of the label are found in the composition of 14CO2, 85.7-85.9 per cent--in lipids, 13,9-14,6 per cent--in prostaglandins.
