China is cloning Pigs on an ‘industrial scale’
BBC hat ‘nen faszinierenden Artikel über die weltgrößte „Cloning Factory“ in China, die im Jahr 500 geklonte Schweine „produziert“.
The first shed contains 90 animals in two long rows. They look perfectly normal, as one would expect, but each of them is carrying cloned embryos. Many are clones themselves. This place produces an astonishing 500 cloned pigs a year: China is exploiting science on an industrial scale.
To my surprise, we’re taken to see how the work is done. A room next to the pens serves as a surgery and a sow is under anaesthetic, lying on her back on an operating table. An oxygen mask is fitted over her snout and she’s breathing steadily. Blue plastic bags cover her trotters.
Two technicians have inserted a fibre-optic probe to locate the sow’s uterus. A third retrieves a small test-tube from a fridge: these are the blastocysts, early stage embryos prepared in a lab. In a moment, they will be implanted.
