It's Friday, I'm a Judge! Breed: Thoroughbred

Welcome back to another Friday judging clinic! This week, we're returning to the land of Thoroughbreds. I last covered this in a mini breed post, so the text regarding the breed standard is going to sound the same - I'm not one to reinvent the wheel, so I copied and pasted my previous work. 

As always, my personal judging history and credentials can be found on my About Me page. 

Unlike most breed registries, the Jockey Club does not have a specific breed standard for Thoroughbreds. Foals are eligible to register based on their parents, so long as certain conditions are met (both parents are registered, foal was conceived naturally and not through AI or embryo transfer). That being said, there are still ideal characteristics to look for in a Thoroughbred's conformation. They're bred for racing, so their form should follow function. 

With this in mind, these are the characteristics to be looking for: 

  • Small, expressive head with a straight profile 
  • Long slender neck, prominent withers, deep chest 
  • Long sloping shoulders
  • Sloping and muscular croup 

Standard taken from Rousseau, Élise. Horses of the World. Princeton University Press, 2017, p 48.

Like with our Quarter Horses, there can be some wiggle room in the body type. A race fit Thoroughbred is going to look different from an active stud, or a Thoroughbred in a second career.

Let's look at our class! 

Thoroughbred mare
Horse A: Strapless
Thoroughbred stallion
Horse B: Cigar
Thoroughbred stallion
Horse C: Smarty Jones

Take a minute and evaluate the three models. Where is form following function? Is every horse necessarily in race fit condition here? When you're ready, my placings can be found under the jump. ↓
