Japan's Kyodo News Agency quoted ishikawa Prefecture in Japan on the 14th as saying that the world's first somatic cloned cow "Noto" raised at the Livestock Production Test Site of the Comprehensive Research Center for Agriculture and Forestry (The county's Baodashi Mizu town) died at the age of 19 years and 10 months. Or die of old age, the detailed cause of death is under investigation.

According to the prefecture, Noto would lie sideways in the barn from around the 4th of this month, requiring infusions to supplement nutrition. He had been able to feed himself before, but the situation suddenly deteriorated on the afternoon of the 14th, and the veterinarian in charge of care confirmed his death at about 4 p.m.

Born in July 1998, Noto is the world's first cloned cow to use adult bovine somatic cells. Jointly researched by Ishikawa Prefecture and University, the technique of Dolly, a cloned sheep born in the United Kingdom, was used. Kaga, who was born as twins, is still housed at the test site.

After the births of Noto and Kaga, several somatic cloned cows were born in various parts of Japan, but most of them died or were miscarried in a short period of time. Both Noto and Kaga have given birth to calves. Surveys on whether somatic cloned cattle have a longer or shorter lifespan than regular cattle are said to be under way recently.

The lifespan of ordinary cattle is generally about 20 years. The person in charge said: "(Noboru) is very tenacious and has survived longer than expected. We have tried our best to do the best, and it is a pity that we did not live to be 20 years old."
