UTICAJ SISTEMA GAJENJA I GENOTIPA KOKOŠI NOSILJA NA SADRŽAJ HOLESTEROLA U JAJIMA

Abstract

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.
