Marbach stud, Horse stud farm in Gomadingen, Germany.

Marbach stud is Germany's oldest state stud farm, run by Baden-Württemberg in Marbach, part of Gomadingen, with additional facilities in Offenhausen and St. Johann. It keeps about 520 to 600 horses, including Württemberger warmbloods, Black Forest Horses, Arabians, Thoroughbreds and Haflingers. The stud is known for its Arabian breeding and the annual stallion parade.

The stud was founded around 1477 by Count Eberhard V as a private breeding operation and converted to a state-run facility in 1573 to improve local horse breeding. This transformation made it a major center for equine development in the region.

The annual stallion parade, held over two weekends in September and October, presents stallions and mares of several breeds, among them Württemberger warmbloods, Black Forest Horses and Arabians. The stud also runs courses in riding and driving and trains instructors.

The facility operates riding and driving schools that train around 600 students yearly. Visitors can explore the grounds and observe horses in their daily routines throughout the property.

The stallion Bairactar, King Wilhelm I's personal mount, was a founding sire of the Württemberg Arabian line; his prepared skeleton is kept in the stud museum at Offenhausen. The Egyptian stallion Hadban Enzahi, imported in 1955, has a monument on the stud grounds.
