This finding has significant implications, especially for the broiler industry where, up until now, genetic selection has been predominately based around growth rates and feed conversion post-hatch. This approach has led to some problems in fast growing broilers, such as skeletal issues. If factors in yolk are responsible for the development of certain phenotypes, then knowledge of those factors may pave the way for specific (and targeted) manipulation of the diet of broiler breeder hens to alter yolk composition and improve broiler health outcomes.
