Russian Trotter

Horse

The Russian Trotter or Métis Trotter was developed in Russia to create a horse with a faster trotting speed than the older Russian Orlov Trotter. 156 Standardbred stallions and 220 mares were imported from the United States between the years of 1890 and 1914. Being the fastest trotter in the world, the Standardbred was crossed with the Orlov Trotter, producing at first animals who were faster but of lower quality. Further breeding produced a larger trotter of better quality. Further infusions of Standardbred and Orlov Trotter were added to the best offspring, and periodic infusions of both breeds are still added to this day.
