Article 2 - Thoroughbred Racing and Breeding
225 - Registration of Race Horses.

§ 225. Registration of race horses. The true name, sex and age, and
also the pedigree, unless such pedigree is unknown, of every horse,
mare, gelding, colt or filly shall be registered with the jockey club,
United States trotting association, American quarter horse association,
the national steeplechase and hunt association or such other entity as
the commission may designate before it shall be eligible to compete in
any race conducted under a license or franchise of the commission and
such name shall continue to be its true name unless and until the same
shall be changed according to the rules and regulations of such
organization. The class to which any such animal belongs for the purpose
of the entry or competition in any race shall be determined by the
public performance thereof in former contests or trials of speed, as
prescribed by the printed rules of the person, association or
corporation sponsoring such race. No horse, mare, gelding, colt or filly
shall be eligible to compete in any race, unless it is first
microchipped and registered with the jockey club, United States trotting
association, American quarter horse association, the national
steeplechase and hunt association or such other entity, as applicable
and as the commission may designate. The commission may request that all
microchip information be provided and available to the commission as
necessary pursuant to this chapter.
