 Regulation and control of racing in the United States is highly fragmented.Generally, a state government entity in each American state that conducts racing will license owners, trainers and others involved in the industry, set racing dates, and enforce drug restrictions and other rules.Pedigree matters and the registration of racing colors, however, are the province of The Jockey Club, which maintains the American Stud Book and approves the names of all Thoroughbreds.
