Is there a difference between the Dun Factor Horse, the SMR horse and the Sulphur Horse

According to D. Philip Sponenberg, DVM, PhD, of Virginia-Maryland Regional College of Veterinary Medicine and Technical Coordinator, American Livestock Breeds Conservancy: "The three main tools for evaluating horses (for Spanish descent) are the history behind the individual horse, the appearance of the horse, and the blood-type of the horse." During August 1993, Dr. Sponenberg came to Utah and inspected thirty-four Sulphur horses that the BLM had adopted out to various individuals. His subsequent evaluation states: "The Sulphur Herd Management area horses that are present as adopted horses in the Salt Lake City area appear to be of Spanish phenotype. The (Sulphur) horses were reasonably uniform in phenotype, and most of the variation encountered could be explained by a Spanish origin of the population. That, coupled with the remoteness of the range and blood-typing studies, suggests that these horses are indeed Spanish. As such they are a unique genetic resource, and should be managed to perpetuate this uniqueness.

A variety of colors occurs in the herds, which needs to be maintained. Initial culling in favor of Spanish phenotype should be accomplished, and a long term plan for population numbers and culling strategies should be formulated. This is one population that should be kept free of introductions from other herd management areas, as it is Spanish in type and therefore more unique than horses of most other BLM management areas." He later states: "The horses removed during the last few years from the Sulphur Herd Management Area are Spanish in type. The fact that the horses were so consistently Spanish type is evidence that these horses have a Spanish origin," This evaluation therefore establishes the Sulphur horses as Spanish in appearance.
