'Strong pig' clones developing well

SHENZHEN, Guangdong - Six piglets cloned from an animal famous for surviving more than a month trapped under the rubble of the Wenchuan earthquake are developing at a steady pace, say scientists.

Du Yutao, who is leading the project, said the piglets are lively and growing day by day at the Beijing Genomics Institute's experimental base in Huizhou, Guangdong province.

"After several weeks of being taken care of by the staff here, each piglet weighs more than 6 kilograms," the doctor told China Daily on Monday.
