Currently, it is under threat of extinction, because according to the existing international classification, a breed with a uterine stock of less than 1000 breeds has a threatening status, its size is insufficient to compensate for genetic losses.
However, the preservation of the Yakut cow is of universal importance, because it is the only aboriginal breed of livestock that can survive in extreme climatic conditions, which means that it has incredibly strong immunity that does not suffer from such popular diseases as tuberculosis and leukemia.
The reason for this is long-term adaptation and natural selection. Its unique genes can allow humanity to survive in the event of a global pandemic of livestock, when most breeds can not fight the epidemic of a deadly disease due to the weakness of their immunity.
