Jutland horse 405 stud farms were devoted to their breeding in Denmark, but since that time, population numbers have dwindled. Though numbers dropped, a 2008 study of the 716 Jutland horses in the Danish studbook at that time concluded that little risk of the Jutland becoming extinct existed due to inbreeding or low genetic diversity. The study, which also included populations of the Knabstrupper and Fredericksborg breeds, theorized that the greatest loss to genetic diversity for horses in Denmark would be through the extinction of the Jutland breed, because of its genetic distance from the other two native breeds.

Jutland horse the Jutland being used by Viking raiders in what is now Great Britain. The first written record is from the 12th century, when they were popular as war horses. Some infusion of bloodlines from other breeds occurred in the 18th century, but the modern Jutland type only began about 1850 with the addition of blood from several other breeds, mainly draft horses. A stud book was created in the late 19th century, and the Jutland population grew to a maximum around 15,000 by 1950. Numbers subsequently declined, and as of 2011, only an estimated 1,000 horses remained. The Jutland is
