Abstract
Chicken eggs are biologically high value foods and the human organism utilises their nutritional value at a high percentage. The aim of this paper is to determine the influence of poultry housing system on egg quality. The study included the determination of egg quality from egg laying hens of different ages, originating from free, floor and cage systems, to a total of 60 samples. Free range eggs weighed the most (averaging 59,35 g) and in comparison to cage raising system, measuring higher egg index (75,29 : 74,30) and a thicker shell (0,44 : 0,43 mm). The water amount was highest, and the protein amount was lowest in free range eggs. Eggs from the aspect of their production characteristics and quality in terms of chemical composition recorded higher values in conventional cages in comparison to free range, while eggs originating from free range and enriched cage systems recorded higher values from a poultry welfare standpoint.
