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 ...
Myosin-heavy chain myopathy (MYHM) is a genetic muscle disease found primarily in the American Quarter Horse and crossbred horses with significant Quarter Horse bloodlines. It was added to the AQHA genetic testing panel in 2022. [ 1 ]
One study found from a group of visually inspected registered Paints, 18% of breeding stock solids and 35% of bald-faced horses were actually frames. [9] However, over one-quarter of Paints registered in the "overo" category were not frames, and conversely, 10% of horses registered as tobiano also carried frame genetics. [ 9 ]
The movement of horses at an animal welfare charity's farm has been suspended after a mare tested positive for a highly infectious respiratory disease. A recent arrival at World Horse Welfare's ...
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.
Twilight, the Thoroughbred mare who was the first horse to have its genome fully sequenced. The horse genome was first sequenced in 2006. The Horse Genome Project mapped 2.7 billion DNA base pairs, [1] and released the full map in 2009. [2] The horse genome is larger than the dog genome, but smaller than the human genome or the bovine genome. [2]
Phillip Sponenberg of the Virginia–Maryland Regional College of Veterinary Medicine, an expert on horse breeds, observed that, physically, the horses conform to the Colonial Spanish Horse type. [9] Genetic studies have also revealed that the herd exhibits a high degree of genetic diversity, [11] and BLM has acknowledged the genetic uniqueness ...
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 ]
