China's Mutant Pigs Could Help Save Nation From Pork Apocalypse

(Bloomberg) — Inside a fortress-like megafarm on the outskirts of Beijing, dozens of pink-and-black pigs forage and snooze, unfazed by the chilly spring air. These experimentally bred hogs are fortified with a gene for regulating heat, buffering them against northern China’s hypothermia-inducing winters.

The gene that researcher Jianguo Zhao inserted into the pigs’ DNA is among dozens of examples of genetic engineering underway in China—and in rival laboratories across the world—to create super pigs. For years, the quest was for better-tasting, stronger, and faster-growing swine. Now, in the wake of a devastating global outbreak of African swine fever, the more crucial need is to safeguard food security, and keep hogs alive. 

“The most burning question for scientists is how to make the pig more healthy,” says Zhao, 45, who heads a 20-strong group of researchers and technicians at the state-run Chinese Academy of Sciences’ Institute of Zoology in Beijing, where he’s become a superstar in the world of swine genomics.
