At the beginning of his three-year-old year, Secretariat was syndicated for a record-breaking $6.08 million (equivalent to $ million in ), on the condition that he be retired from racing by the end of the year. Although he sired several successful racehorses, he ultimately was most influential through his daughters' offspring, becoming the leading broodmare sire in North America in 1992. His daughters produced several notable sires, including Storm Cat, A.P. Indy, Gone West, Dehere and Chief's Crown, and through them Secretariat appears in the pedigree of many modern champions. Secretariat died in 1989 due to laminitis at age 19.

Content:  Secretariat was officially bred by Christopher Chenery's Meadow Stud, but the breeding was actually arranged by Penny Chenery (then known as Penny Tweedy), who had taken over the running of the stable in 1968 when her father became ill. Secretariat was sired by Bold Ruler and his dam was Somethingroyal, a daughter of Princequillo. Bold Ruler was the leading sire in North America from 1963 to 1969 and again in 1973. Owned by the Phipps family, Bold Ruler possessed both speed and stamina, having won the Preakness Stakes and Horse of the Year honors in 1957, and American Champion Sprint Horse honors in 1958.

When Secretariat first retired to Claiborne Farm, his sperm showed some signs of immaturity, so he was bred to three non-Thoroughbred mares in December 1973 to test his fertility. One of these, an Appaloosa named Leola, produced Secretariat's first foal in November

Content:  major stakes winners, including: Ultimately, Secretariat officially sired 663 named foals, including 341 winners (51.4%) and 54 stakes winners (8.1%). There has been some criticism of Secretariat as a stallion, mainly because he did not produce male offspring of his own ability and did not leave a leading sire son behind, but his legacy is assured through the quality of his daughters, several of whom were excellent racers and even more of whom were excellent producers. In 1992, Secretariat was the leading broodmare sire in North America. Overall, Secretariat's daughters produced 24 Grade/Group 1 winners. As a broodmare sire, Secretariat's most notable progeny were: Through Weekend Surprise and Terlingua

Inbreeding to Secretariat has also proven successful, as exemplified by numerous graded stakes winners, including two-time Horse of the Year Wise Dan, as well as sprint champion Speightstown. Secretariat's paddock at Claiborne Farm bordered three other stallions: Drone, Sir Ivor, and Hall of Fame inductee Spectacular Bid. Secretariat did not pay much attention to Drone or Sir Ivor, but he and Spectacular Bid became friendly and occasionally raced each other along the fence line between their paddocks.

Although Somethingroyal was unplaced in her only start, she had an excellent pedigree. Her sire Princequillo was the leading broodmare sire from 1966 to 1970 and was noted as a source of stamina and soundness. Her dam Imperatrice was a stakes winner who was purchased by Christopher Chenery at a dispersal sale in 1947 for $30,000. Imperatrice produced several stakes winners and stakes producers for the Meadow. Prior to foaling Secretariat at age 18, Somethingroyal had already produced three stakes winners: Sir

Content:  Secretariat was sired by Bold Ruler, who led the North America sire list eight times, more than any other stallion in the 20th century. He also led the juvenile (two-year-old) sire list a record six times. Before Secretariat's Triple Crown run, Bold Ruler was often categorized as a sire of precocious juveniles that lacked stamina or did not train on past age two. However, even before Secretariat, Bold Ruler actually had sired 11 stakes winners of races at 10 furlongs or more. Ultimately, seven of the ten Kentucky Derby winners in the 1970s can be traced directly to Bold Ruler in their tail 
Title: Lady's Secret
Content:  Lady's Secret was sired by U.S. Triple Crown champion Secretariat and out of Great Lady M., a daughter of Icecapade who was a half brother to Ruffian. Lady's Secret was also closely related to Ruffian on her sire's side since Secretariat and Reviewer (Ruffian's sire) shared a sire in Bold Ruler. Lady's Secret was bred by Robert H. Spreen at Lucas Farm in Oklahoma. Spreen sold her for $200,000 to Mr. and Mrs. Eugene Klein (former owner of the San Diego Chargers), and she was prepared for racing by Hall of Fame trainer D. Wayne Lukas. She was a small horse, weighing no more than about 900 pounds.
Title: Secretariat (film)

The film chronicles the life of Thoroughbred race horse Secretariat, winner of the Triple Crown in 1973.

Filming took place on location in Louisville and Lexington, Kentucky, and around Lafayette and Carencro, Louisiana. The film premiered in Hollywood on September 30, 2010, and was released in the United States on October 8, 2010, by Walt Disney Studios Motion Pictures.
