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.
The aim of this study was to determine the effect of the rearing system (floor
and organic) and the genotype of laying hens (Isa Brown hybrid and New
Hampshire breed) on the cholesterol content in eggs. 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.
