Every hatchery’s labor of removing male chicks after pulling hatch is likely to come to an end, all things are equal with a worldwide acceptance of genetic engineering in poultry breeding and not necessarily imposing the consumption of GMOs on individuals.
What is New?
Gene Editing is the new game-changer. Research on genetic modification could produce a layer breed that only produces non-GMO layer hens, reducing the number of male chicks or possibly eliminating male chicks which are one headache on breeder farms and hatcheries worldwide.
“We can introduce a trait which stops embryogenesis at a very early stage, all-male embryos will cease to develop and will no longer hatch. Excluding male eggs from the incubators will save 50% of the space and energy, thus benefiting sustainability.”
How Genetic Engineering will Change the Breeding Game in Poultry?
The ZZ:ZW sex chromosomal system determines sex in chickens and other animals. Females have a pair of distinct chromosomes (ZW), whereas males have two similar chromosomes (ZZ), unlike the XY sex chromosomal system in humans.
The researchers used genetic engineering to construct a breeding flock of hens with a fatal embryonically inducible gene on the maternal Z chromosome. Male embryonic development is inhibited very early in development when the gene is activated by blue light exposure.
