Secretariat

Greg and I watched the movie Secretariat Saturday. I really liked it. You can't help but fall in love with that horse. Watch it if you never have.

If you saw the movie, this information might be interesting to read. Makes you love him even more.

*from Wikipedia*

In the fall of 1989, Secretariat was afflicted with laminitis, a painful and often incurable hoof condition. When his condition failed to improve after a month of treatment, he was euthanized on October 4 at the age of 19. Popular both as a Triple Crown champion and in retirement, Secretariat was mourned by millions and buried at Claiborne Farm in Paris, Kentucky, given the rare honor of being buried whole; usually only the head, heart, and hooves of a winning race horse are buried, and the rest of the body is cremated.

A necropsy revealed that his heart was significantly larger than that of an ordinary horse. An extremely large heart is a trait that occasionally occurs in Thoroughbreds, linked to a genetic condition passed down via the dam line, known as the "x-factor." The x-factor can be traced to the historic racehorse Eclipse, who was necropsied after his death in 1789. Because Eclipse's heart appeared to be much larger than other horses, it was weighed, and found to be 14 pounds (6.4 kg), over twice the normal weight. It is believed Eclipse passed the trait on via his daughters, and pedigree research verified that Secretariat traces in his dam line to a daughter of Eclipse. In the 20th century, the heart of Phar Lap was weighed and also documented to be 6.35 kilograms (14.0 lb), or essentially the same size as that of Eclipse.

At the time of Secretariat's death, the veterinarian who performed the necropsy, Dr. Thomas Swerczek, head pathologist at the University of Kentucky, did not weigh Secretariat's heart, but stated, "We just stood there in stunned silence. We couldn’t believe it. The heart was perfect. There were no problems with it. It was just this huge engine." Later, Swerczek also performed a necropsy on Sham, who died in 1993. Swerczek did weigh Sham's heart, and it was 18 pounds (8.2 kg). Based on Sham's measurement, and having necropsied both horses, he estimated that Secretariat's heart probably weighed 22 pounds (10.0 kg), or about two-and-a-half times as large as that of the average horse.
