CRISPR-edited pigs resist deadly swine fever, offering safer, more sustainable farming.
Gene-edited pigs resistant to classical swine fever have been developed using CRISPR technology, altering the DNAJC14 protein to block viral replication.
Tested at the UK’s Animal and Plant Health Agency, the edited pigs showed no illness or virus presence after exposure, unlike unedited controls.
The breakthrough, led by the University of Edinburgh’s Roslin Institute, could reduce mass culling, improve animal welfare, and lower farming costs.
The same modification may protect cattle and sheep from related viruses.
Regulatory approval for gene-edited livestock is pending in England, though similar animals are already approved in the U.S., Japan, and Brazil.
No adverse effects have been observed in multiple generations, and the technology is being considered for commercial use.
