Cilj ovog rada je bio da se utvrdi uticaj sistema gajenja (podnog i organskog) i genotipa kokoši nosilja (Isa Brown hibrid i New Hampshire rasa) na sadržaj holesterola u jajima. U sedam navrata tokom jednogodišnjeg proizvodnog ciklusa (24, 32, 40, 48, 56, 64 i 72. nedelja starosti nosilja) uzeto je po 15 jaja iz sve četiri ogledne grupe, i na zbirnim uzorcima je utvrđen sadržaj holesterola. Na osnovu dobijenih rezultata, može se zaključiti da su jedinke iz podnog sistema gajenja imale manji sadržaj holesterola u jajima u odnosu na organski gajene kokoši nosilje, dok se uticaj genotipa na ovu osobinu ne može sa sigurnošću definistati.

On seven occasions during the one-year production cycle (24, 32, 40, 48, 56, 64 and 72 weeks hen's age), 15 eggs from all four experimental groups were taken, and cholesterol content was determined on pooled samples. Based on the obtained results, it can be concluded that laying hens from the floor rearing system had lower cholesterol content in eggs compared to organic, while the effect of genotype on this trait cannot be defined with certainty.
