Sažetak
The objective of this study was to compare egg and major egg components’ weight, as well as yolk to albumen ratio, laid by hens of two commercial breeds (Hy-Line and ISA Brown) and a Croatian local breed, Hrvatica. Eggs were collected from different production systems: Hy-Line-enriched cage housing, ISA Brown-aviaries housing, ISA Brown-free range raising, Hrvatica hen-free range raising (organic production). The heaviest eggs were laid by theHy-Line hens from enriched cage housing (70.06 g), while Hrvatica hens laid significantly the lightest eggs (51.01 g). The eggs from Hrvatica hens had significantly the lowest albumen percentage (53.30%) and highest yolk percentage (33.96%). Consequently, the yolk to albumen ratio was the highest for Hrvatica hen eggs (0.609), which is on average 44.6%, 52.6% and 36.8% higher in comparison to eggs from cage housed Hy-Line, aviaries housed ISA Brown and free-ranged ISA Brown hens, respectively.
