'Good fat' sheep cloned in China

2012-04-24 10:26

Hong Kong - Chinese scientists have cloned a genetically modified sheep containing a "good" type of fat found naturally in nuts, seeds, fish and leafy greens that helps reduce the risk of heart attacks and cardiovascular disease.

"Peng Peng", which has a roundworm fat gene, weighed in at 5.74kg when it was born on March 26 in a laboratory in China's far western region of Xinjiang.

"It's growing very well and is very healthy like a normal sheep," said lead scientist Du Yutao at the Beijing Genomics Institute (BGI) in Shenzhen in southern China.

Du and colleagues inserted the gene that is linked to the production of polyunsaturated fatty acids into a donor cell taken from the ear of a Chinese Merino sheep.

The cell was then inserted into an unfertilised egg and implanted into the womb of a surrogate sheep.

Safety concerns

"The gene was originally from the C elegans [roundworm] which has been shown [in previous studies] to increase unsaturated fatty acids which is very good for human health," Du said.

China, which has to feed 22% of the world's population but has only 7% of the world's arable land, has devoted plenty of resources in recent years to increasing domestic production of grains, meat and other food products.

But there are concerns about the safety of genetically modified foods and it will be some years before meat from such transgenic animals finds its way into Chinese food markets.

"The Chinese government encourages transgenic projects but we need to have better methods and results to prove that transgenic plants and animals are harmless and safe for consumption, that is crucial," Du said.

Apart from BGI, other collaborators in the project were the Institute of Genetics and Developmental Biology at the Chinese Academy of Sciences, and Shihezi University in Xinjiang.

The US is a world leader in producing GM crops. Its Food and Drug Administration has already approved the sale of food from clones and their offspring, saying the products were indistinguishable from those of non-cloned animals.

US biotech firm AquaBounty's patented genetically modified Atlantic salmon are widely billed as growing at double the speed and could be approved by US regulators as early as this year.

    The meat also gives you a healthy cool coat. No bleating about the bush...

    Can't they clone some rhinos with huge horns?

    fat from China. I believe it can change a racist way of thinking.south africa needs it to cure some racists who think they are better and superior because of the colour of their skin

      Bafana, when you see two turds, you will still have a racist utterly stupid remark to make..

    Maybe they can also clone Rhino horn. It wil save our animals.
