The objective of this study was to compare egg quality and yield in laying hens of two different housing systems indoor and free range.
In this study, 120 H&N (Nick-Chick) white egg layer pullets were used. They were divided to equally two groups free range and indoor housing system. Indoor birds were individually caged while free range birds were allowed to access free range grass paddock (red clover+ fescue + brome grass area, 4 m2/1 bird) plus floored area with wooden shavings. Standard feeding regimen was applied on experimental laying hens. Their egg traits were recorded during the period of 21-46 weeks old. Housing system has a significant effect on layer final body weight (P˂0.01). Free range group was higher than indoor group about total egg/month, hen/house and hen % when egg yield compare to the groups. Egg weight was higher in indoor group (59.04-60.22 g), but shell thickness (0.38-0.37 mm) and yolk index (46.07-44.91) were higher free range system (P˂0.01). Housing systems have not significant effects on other egg characteristics such as shell ratio, shape index and albumen index.
