ABSTRACT
The study was conducted on 90 thirty-week-old Messa H-43 layers divided into 3 groups. The
control group was fed a diet without oil seeds, while the RLP and RLP+E groups were given a diet
containing a mixture of 00 rapeseed, linseed, and evening primrose seed. Vitamin E, 200 mg/kg, was
added to the RLP+E diet. After 4 weeks, egg quality, fatty acid content, and the lipid oxidation level
were determined. Half of the collected eggs were examined the next day and the second half, after 20
days of storage at 12°C. No effect of feeding was found on egg quality. Eggs from groups RLP and
RLP+E had less saturated fatty acids and more polyunsaturated fatty acids. Egg weight and albumen
quality decreased and yolk content increased during storage, irrespective of the diet. Changes in fatty
acid content in yolk during storage were found. Diet and the storage had insignificant effect on
oxidation of yolk lipids.
