Gene Editing Could Improve Heat Tolerance


The detrimental health, well-being, and productivity effects of heat stress in dairy cattle could one day be partially solved through gene editing.


The currently experimental technology removes an undesirable genetic trait in an animal and replaces it with a more favorable one at the genome level, known among researchers and regulators as an “intentional genomic alteration” (IGA). It is possible to introduce traits within a species, and between species.


In the case of heat stress, two approaches are being taken by researchers to help cattle cope:
