Part-Arabian

In the modern era, crossbreeding has been popular to combine the best traits of two different breeds, such as color, size, or ability to specialize in a particular equestrian discipline.

Thus, in the modern era, the desire to recognize and acknowledge Arabian breeding in non-purebred horses has led to the formation of partbred sections in many purebred Arabian registries in order to record the pedigrees of crossbreds.

Some registries, particularly those for sport horses and various warmbloods, have an open or partially open stud book that still allows some infusions of Arabian blood as well as that of other breeds, sometimes based on a documented Arabian pedigree, sometimes on a pedigree plus a studbook selection process.

Some breeds, such as the Thoroughbred, acknowledge Arabian ancestry with named, documented horses in their stud books, but no longer accept new infusions of Arabian blood and the breed is considered a purebred in its own right.

In some breeds, such as the Percheron, Arabian influence is considered highly probable, but dates back hundreds of years and thus is difficult to conclusively prove as pedigree records cannot be linked to individual animals.
