Scientists of the Institute of Cattle Breeding in Japan's Gifu Prefecture successfully obtained a clone from a frozen bull cell that died 16 years ago
It is noteworthy that for the 13-year-old life of the bull Yasufuku - the founder of the local breed of cows - from him was born 30 thousand calves. Currently, almost all the head of the Hidagyu breed are its descendants.
Scientists from the Research Institute of Cattle Breeding managed to grow a testicle cell with the help of a new technology, then isolate the nucleus from it with the DNA information carrier and replace the core with the core of the unfertilized ovum of the cow.
The first bull clone was born in November 2007, and he and his two brothers who were born last year are alive and distinguished by excellent health. "The fact of creating healthy animals from cells frozen in the era of imperfection of this technology is truly impressive, which gives hope for the possibility of restoring the extinct and exterminated animal species," the Institute's scientists believe.
The success of Japanese scientists can have not only scientific but also industrial significance. After all, till now the biggest problem of cloned animals was considered their high mortality in the first months after birth.
And on the eve of the working group of the government committee on food safety, considering the safety of using meat of cloned animals for food, concluded that "clones of pigs and cows are no different from those born naturally." The main conclusion of the commission was the conclusion that if a cloned animal survives to 6 months, its further development and health is no different from ordinary cows and pigs.
Thus, if the safety of cloned beef and pork is confirmed by the food safety committee, then this year it is possible to expect the receipt of such meat for sale. At present, 557 cows and clone bulls were born in Japan, but only 82 survived.
