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 ...
The Belgian Draft Horse is one breed in which JEB occurs Junctional epidermolysis bullosa ( JEB ) is an inherited disorder that is also known as red foot disease or hairless foal syndrome . [ 1 ] JEB is the result of a genetic mutation that inhibits protein production that is essential for skin adhesion. [ 2 ]
It is a genetic dominant condition, though not all horses who inherit the gene will show clinical signs of being affected and the environmental triggers are not well understood at present. An estimated 7% of all Quarter Horses carry this gene. There are two forms, both linked to the same genetic variant. Affected horses may exhibit one or both ...
Hereditary equine regional dermal asthenia (HERDA), also known as hyperelastosis cutis (HC), is an inherited autosomal recessive connective tissue disorder. It develops from a homozygous recessive mutation that weakens collagen fibers that allow the skin of the animal to stay connected to the rest of the animal.
This inherited disease is characterized by violent muscle twitching and substantial muscle weakness or paralysis among affected horses. HYPP is a dominant genetic disorder ; therefore, heterozygotes bred to genotypically normal horses have a statistic probability of producing clinically affected offspring 50% of the time.
A genetic test for WFFS was made commercially available in 2013. Approximately 9–11% of Warmblood horses are carriers, with lower carrier frequencies in Thoroughbreds and Knabstruppers. [2] Horses that are heterozygous for WFFS are phenotypically normal, so genetic testing is necessary to prevent breeding carriers.
Images from the 9th century show a horse similar to the Jutland being used by Viking raiders in what is now Great Britain. A stud book was created in the late 19th century, and the Jutland population grew to a maximum of around 15,000 by 1950. Numbers subsequently declined, and as of 2011 it is estimated that there are only about 1,000 horses ...
Degenerative suspensory ligament desmitis, commonly called DSLD, also known as equine systemic proteoglycan accumulation (ESPA), is a systemic disease of the connective tissue of the horse and other equines. It is a disorder akin to Ehlers–Danlos syndrome being researched in multiple horse breeds.
