Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.

One of the major turning points in this plant history is undoubtedly the appearance of angiosperms (flowering plants) towards the early Cretaceous. The first dinosaurs lived in a plant universe that is noticeably different from the one we know today because it is dominated by ferns, cycads, conifers and plants that are now extinct.
