摘要：
Disclosed is a cold-resistant and lean-type transgenic pig and a preparation method therefor, which relate to the field of genetic engineering. By transferring a mouse uncoupling protein 1 gene into the genome of a pig, a transgenic pig is obtained which can not only resist the cold but also have an increased lean meat rate by reducing fat deposition. Simultaneous improvement of two important production traits of pigs through the site-directed single gene manipulation not only lays a foundation for the application and basic research of genetic editing for big animals, but also provides with breading researchers a new way of thinking for improving traits of livestock.
