幻灯片 3Will cloned pigs in China receive global acceptance?
(Reuters)—Chinese geneticist Du Yutao peers at an ultrasound(超声波)monitor scanning the underbelly of a pregnant sow(母猪)—one of China's latest technological tools to feed its people better.
----
幻灯片 4The 20 odd hogs(食用猪)at this farm in Guangdong province in southern China are no ordinary pigs, but rather surrogate(代用品)sows carrying cloned piglets.
Du's colleagues are cloning pigs at a laboratory an hour's drive from the farm.
They remove DNA from skin cells taken from the ear of a prized male pig and transfer them into pig egg cells cleared of their nuclei(细胞核). The resulting embryos(胚胎)are surgically implanted into surrogate sows.
----
幻灯片 5“Now we import valuable male pigs from Denmark and the United States. They are costly to buy, transport and influential to a lot of disease during transportation，” said Du, head of cloning and genetic engineering at the Beijing Genomics Institute.
“With this technology, we can import small numbers of pigs and mass produce them in China.”
And international experts believe China can take a leading role in promoting the eventual acceptance of cloned animals and even transgenic—or genetically modified(GM)—produce.
