Making a baby horse is easy, right? Take a mom and a dad and 11 months later, you get a foal. In today's age of artificial insemination, embryo transfer, surrogates, and cloning, it's not necessarily that simple. In this two-part blog series, I'll give an update of some famous Thoroughbred offspring and explain some techniques that the breeding industry is not allowed to use.
The Jockey Club
North America's official registry for the Thoroughbred, including racehorses, is The Jockey Club. Over 30,000 horses per year are added to The American Stud Book; there are 445,000 names in active use in the book.
According to The Jockey Club, in order to be eligible for registration, foals need to be "genetically typed and qualified by parentage verification." Only foals that were bred via live cover (the stallion bred the mare naturally) are eligible. The same mare that was bred must give birth to the foal. Cloning, artificial insemination, embryo transfer, or other forms of genetic manipulation are not allowed.
Every Thoroughbred's birthday is January 1st – so breeders make every effort to have foals born as close to, but after, that date as possible. What a nightmare it would be to have a foal born on December 31st and turn a year old the following day! (Thoroughbred races are run by age – this would be a major disadvantage.)
Famous Foals
Every year from January through late spring, announcements are made of new foals of racing champions. Here's a sampling of 2010's news so far:
- Curlin (2008 and 2009 Horse of the Year) sired his first filly, born January 12, 2010 in Kentucky
- Big Brown (Kentucky Derby winner) sired his first filly, born January 12, 2010 in Kentucky
- Barbaro (Kentucky Derby winner; heroically fought tragic leg break but died) was going to have a full sister born this year, but she was aborted by her dam (mother) on December 24, 2009
