The research was conducted on 120 laying hens of Tetra SL provenience, which were divided into two experimental groups (K and P), with 60 laying hens in each group (12 replications, 5 hens per replication). The control group was fed standard diet, while laying hens of experimental groups were given modified diet supplemented with 5% of oil mixture, 0.5 mg/kg organic selenium, 200 mg/kg lutein and 200 mg/kg vitamin E. Portion of n-3 PUFA was significantly better in designed eggs than in

Content of selenium, lutein and vitamin E in designed eggs was statistically significantly higher than in conventional eggs (P<0.001). The content of selenium in egg yolks in conventional eggs was 0.053 μg/g and in designed eggs 0.143 μg/g, and in egg whites 0.387 μg/g and 0.662 μg/g, respectively (P<0.001). Lutein content increased from 12.44 μg/g inconventional eggs to 104.95 μg/g in designed eggs, while vitamin E increased from 12.5 μg/g to 19.82 μg/g egg yolk. Sažetak U istraživanju je korišteno 120 nesilica provenijencije Tetra SL, podijeljenih u dvije pokusne skupine (K i P) sa 60 nesilica po skupini (12 ponavljanja po 5 komada). Kontrolna skupina konzumirala je standardnu smjesu dok su nesilice pokusne skupine dobivale modificiranu smjesu u koju je dodano 5% mješavine ulja, 0,5 mg/kg organskog selena, 200 mg/kg luteina i 200 mg/kg vitamina E. Udio n-3 PUFA bio je značajno bolji kod dizajniranih jaja u odnosu na konvencionalna jaja (3,76% i 1,69%, P<0,001). Omjer n-6/n-3 PUFA u pokusnoj skupini bio je za više od dva puta povoljniji nego u kontrolnoj skupini (5.91 vs. 13,34; P<0.001). Sadržaj selena u Original scientific paper μg/g, odnosno 0.387 μg/g i 0.662 μg/g (P<0.001). Sadržaj luteina povećan je od 12.44 μg/g kod konvencionalnih jaja na 104.95 μg/g dizajniranih jaja, a vitamina E također je povećan od 12.5 μg/g na 19.82 μg/g žumanjka.
