ABSTRACT
Two groups of nine hens were fed a control diet or a diet supplemented with 7.5 g/kg CLA preparation
for 5 weeks. Eggs were collected in the last week and their fatty-acid (FA) profile in yolks determined.
Dietary CLA resulted in increased contents of saturated FA and CLA isomers, especially cis-9,trans-11 and
tt CLA, decreased the content of mono- and polyunsaturated FA. The increased content of CLA isomers and
reduced content of arachidonate in egg yolks can be considered beneficial for human health
