Popis:	In this experiment the effects of different housing systems on physical indicators of egg yolk and egg albumen quality of table eggs were studied. Hens of laying hybrid Lohmann Brown Lite were housed in two different housing systems, in enriched cage or on floor housing system. In both systems, the hens were kept under standard bioclimatic conditions. Eggs (n = 1080) were collected from the first phase of the laying cycle, at monthly intervals, at the age of laying hens 30-42 weeks. Egg weight (g), egg specific weight (g.cm-3), egg shape index (%), eggshell weight (g), eggshell percentage (%), and average eggshell thickness (µm) were evaluated. In the indicators of the whole egg quality was statistically significantly higher (P
