Abstract

The aim of this study was to evaluate the effect of genotype and housing system of hens on fatty acid composition of egg yolk. Total 64 eggs of two genotypes (Lohman LSL and Czech hen) reared in cages and litter system were compared. Results of the study showed that the highest values of saturated, monounsaturated and polyunsaturated fatty acids had Czech hen housed on litter. Whereas, Lohmann LSL housed on litter had the lowest values. Significant effect of genotype was determined in all fatty acids and the effect of housing system in C15:0, C20:4, C22:2 fatty acids and PUFA (n-6/n-3). The interaction between genotype and housing system was significant only in C24:1 and C22:2 fatty acids.
