Sweatblood horses, really different

The Khan's Blood Horse, produced in the Akhal Oasis between the Kopet Mountains and the Karakum Desert in Turkmenistan, is one of the oldest horse breeds in the world, bred over 3,000 years.
There are three purebred horses in the world: the sweatblood, the Arabian and the English horse. Of these, the sweatblood is the purest horse breed, and both the Arabian and English horses have the blood and genes of the sweatblood. According to horse history experts, the sweatblood is actually the Akhaltskin horse that still runs in Turkmenistan.
The Akhaltsekin horse has flourished from ancient times and has never broken its bloodline. There are Akhaltsekin horses in Turkmenistan, Russia, Kazakhstan and Uzbekistan, with a total population of about 3,000 horses, of which more than 2,000 are in Turkmenistan.
