La. Rev. Stat. § 4:165.1

If, at any race meeting, the number of accredited Louisiana bred races falls below seventy-five percent of those scheduled, the purse committee of the Louisiana Thoroughbred Breeders Association may authorize the association conducting that meeting to offer Louisiana bred preferred races on a daily basis as substitute or extra races on the program of that association until the number of accredited Louisiana bred races reaches ninety percent of those carded. Conditions and purses of any such race shall be approved prior to offering such races by both the Louisiana Thoroughbred Breeders Association purse committee and the racing association offering such race. Purse supplements offered from Louisiana Thoroughbred Breeders Association funds for Louisiana bred races shall not be awarded to non-Louisiana bred horses earning purse monies in such races, but shall be retained by the association for reuse as purse supplements in other races scheduled for Louisiana bred horses. Breeder awards shall be awarded to Louisiana bred horses earning purse monies in such races in the same manner and under the same conditions as other accredited Louisiana bred races. For purposes of future races, a winner of an accredited Louisiana bred preferred race shall be considered the winner of an accredited Louisiana bred race of the same type.
