The NAERIC-member equine rancher horses fall under three distinct types:
- NAERIC Light Horses (Quarter Horses, Paints, Appaloosas and Standardbreds)
- NAERIC CanAm Sport Horses (Thoroughbred stallion to a draft-cross mare)
- NAERIC Draft Horses (Percherons, Belgians, Clydesdales, and Spotted Drafts)
The NAERIC says that the foal produced as a result of PMU pregnancies are in high demand because there are a limited number of reputable breeders who have these foal breeds available.
