Short note: Laying hens may have lost important genes
Published online by Cambridge University Press: 01 August 2011
Extract
The intensive genetic improvement of laying hens has created a hen with an enormous laying capacity when producing in cage systems. In later years, however, it has been obvious that genes or gene combinations which facilitate the birds' ability to interact with other hens in a flock are lost or suppressed due to the narrow breeding goal which has been maximum egg yield in cage systems.
