flag CRISPR-edited pigs resist deadly swine fever, offering safer, more sustainable farming.

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