On the evening of January 18, 2002, a pregnant cow became the focus of the media on a cattle farm in Cao County, Shandong Province. This cow is about to undergo a broken belly production, giving birth to China's first cloned cow "Committee". Unfortunately, the "committee" died a few hours after its birth. The photo set published today is the story of the birth of the first cloned cattle in China, and many of the contents are exposed for the first time.
On January 19, 2002, the day after the birth of the first cloned cow, the "Commissar", another cow was preparing to break the belly. At that time, The Guiyi Group cattle farm in CaoXian County, Shandong Province, transplanted a total of 135 heads, successfully conceived 27 heads, and finally 12 were left after partial miscarriage. This project is a collaboration between the Institute of Zoology of the Chinese Academy of Sciences and the Animal Embryo Research Center of Wulidun in Caoxian County. The first 12 cloned cattle were born, and 5 survived.
On the afternoon of January 19, 2002, the cloned cattle "Koko" was born through a broken abdomen. Koko also had a bad condition after his birth, but after a long period of oxygen infusion and infusion rescue, he finally succeeded in surviving.
On the afternoon of January 19, 2002, the newly born cloned bovine family tried to open its eyes.
Chen Dayuan, a scientist who presided over the large-scale somatic cloning of cattle, visited the newborn cloned cattle at the scene.
The cloned cattle family has a super high standard of treatment, the single room has heating, and three people are responsible for the care.
China's first surviving cloning of the bovine family, its survival marks a major breakthrough in the actual operation of China's cloning technology.
The cloned cattle come from this very simple laboratory in a rural cattle farm.
Researchers are preparing for experiments. The birth of the first cloned cow greatly boosted the confidence of the researchers, who were ready to do larger experiments.
A cow waiting to conceive.
Cao County, Shandong Province, is a well-known cattle breeding county in the country, and Guiyi Group is the largest local cattle breeding enterprise, and the stock of cattle usually exceeds 10,000 heads, which provides a solid foundation for large-scale cattle cloning experiments.
There are many loudspeakers in the cattle farm, and light music is constantly played, which is said to have been learned from Europe and is helpful for cows to produce milk.
After the birth of the cloned cattle, the Guiyi Group cattle farm launched a cloning technology cooperation project with local cattle farmers accordingly. Almost every family raises cattle in the local area, and obtaining a high-yield cow is the desire of every family, and once the cloning technology is used, the gender milk quality of the cow is not a problem.
A local cattle farmer, leading his own cows to the Cattle Farm Institute, decided to try out the new technology with his cattle.
Inside the cattle ranch, several cows are huddled in a narrow wall hole peeking out. What's going on out there? In fact, don't say that they don't understand, maybe humans don't fully understand!
On February 27, 2002, the cloned cattle project in Cao County, Shandong Province, passed the acceptance of the expert group and was confirmed to be another major breakthrough in the field of life science and biotechnology in China.
