Sažetak
The aim of this study was to assess the performance and technological values of eggs of Czech Hen and Oravka breeds housed on litter. The assumption was that the genotype of hens affects their performance, egg weight, and parameters of yolk, albumen and eggshell quality. A total of 30 pullets of Czech Hen breed and 30 pullets of Oravka breed in the age of 17 weeks were included in to the experiment. Environmental conditions corresponded to the standard requirements for laying hens in observed type of housing system. Hen day egg production, egg yield, daily feed consumption per hen, feed consumption per egg and egg weight, egg shape index, proportion and index of yolk and albumen,yolk colour and Haugh units score were monitored in the experiment. From the parameters of eggshell, proportion, thickness, strength and colour of eggshell were observed. Performance parameters of laying hens weren't affected by the genotype of hens. Czech Hen breed showed insignificantly the higher value in all indicators. The significantly (P ≤ 0.01 and P ≤ 0.001) better values of eggshell quality parameters were detected in Czech Hen breed. We found out that Czech Hen breed had also statistically significantly lighter colour of eggshell. There were no significant interbreed differences in egg weight, proportion of yolk and albumen. The egg shape index was significantly higher in Oravka. Index of yolk and albumen was also significantly (P ≤ 0.001) higher in Oravka. Haugh units score, that reflect the quality of the eggs, were found significantly (P ≤ 0.001)higher in Oravka too. On the other hand, yolk colour was detected significantly (P ≤ 0.001) darker for the Czech Hen.
