Highly pathogenic avian influenza and porcine reproductive and respiratory syndrome impose major disease and economic burdens on poultry and swine production. Paula Chen and Kiho Lee examine gene editing as a way to reduce susceptibility and improve animal health. Chen presents genome-editing approaches to preventing poultry disease; Lee discusses improving the genetic value of pigs through gene-editing technology. The programme connects these strategies to the continuing challenges posed by viral outbreaks, evolving PRRS variants and debate about vaccination as a control measure.
