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 Felding's Kamp med Risen"", in which mythic hero Svend Fælling goes on a pilgrimage to Rome and on his journey encounters a giant. Other horses prove too shy or too weak to enable him to confront the giant, so Svend obtains a Jutland horse from a passing miller, who claims that it is strong enough to carry 15 skippund.
