How do livestock farms benefit from genome editing?

Animal breeding could become more efficient with an approach that combines DNA-editing techniques with new reproductive technologies.


Technologies to edit the DNA of animals known as genome editing could improve animal welfare and performance while reducing the environmental footprint of livestock production.


Genome-editing tools are precise and cost-effective and could technically be applied on the farm, scientists say.


Toolkit for breeders


Using genome editing is becoming simpler thanks to the emergence of three cutting-edge reproductive technologies, known as surrogate sire technology, zygote transduction with recombinant adeno-associated virus, and zygote electroporation.


Livestock breeders could soon apply genome editing on the farm by using these new tools, which mobilise genome editing for the first time.


Risks of unintended edits have been significantly reduced in the latest genome-editing technologies. Unintended edits are detected by comprehensive screening methods and, once identified, they can be eliminated using standard breeding strategies.
