Production and Quality Traits of Layers kept in Free Range Housing System
Kemal University, Agriculture Faculty, Animal Science Department, 31060, HATAY/
The objective of this study was
to compare egg quality and yield in laying hens of two different housing
systems indoor and free range.
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.
