From TWHBEA Master Breeder Profile of J. Mac Carter
J. Mac Carter began his breeding program in the 1950s after
purchasing a farm on Midland Road just outside Murfreesboro
with the intention of turning it into a dairy, which he did.
The farm became home to what was, in its time, the best
producing dairy herd in Rutherford County. It was J. Mac
Carter’s ability to study the production records of cows
that gave him the idea that the same principles might work
with horses. It was his belief that somewhere within the
complicated and baffling laws of nature there is a definable
pattern of genes that will produce superior products that
led Carter to produce a string of royally bred and
unquestionably talented Tennessee Walking Horses.
He started his breeding program with a band of mares by
Midnight Sun, Merry Go Boy and Miller’s Wilson Allen, which
he out crossed with other prominent walking horse families.
The first broodmare of significance Carter purchased was
Shadow’s Nookie by Goy Boy’s Shadow and out of Jay’s
Traveler, who was also the dam of the successful show mare
Midnight Mystery. When Carter bought Shadow’s Nookie she was
in foal to The Impala and the next spring she gave birth to
Impala’s Shadowette, the dam of 1973 World Grand Champion
Delight Bummin’ Around, Delight’s Tramp, Delight’s Vamp and
Over the years Carter continued to gather a herd of
outstanding broodmares, and his reputation as a breeder of
great horses was solidified. Other horses produced by the J.
Mac Carter breeding program include Delight’s Double Clutch,
Bum’s Storm Cloud, Ebony’s Hacksaw, Time To Deal, Delight’s
Delightful and Delight’s Caper.
