Stepping into the world of horses can feel like entering a whole new environment, filled with unique terms and long-standing traditions. If you’ve ever found yourself wondering what words like “stallion,” “filly,” or “rig” really mean, you’re not alone.
The horse community uses specific vocabulary to describe different aspects of horses, which can be a little confusing at first. But don’t worry, learning these terms is part of the journey!
Below, you’ll find definitions of the main gender terms used to describe horses, along with other important terms related to age and role. Whether you’re new to horses, a lifelong animal lover, or just curious, understanding these terms makes the horse world easier to navigate and even more fascinating.
Horse Genders
There are three main gender terms used for horses: mare, gelding, and stallion. While all horses are biologically male or female, these specific terms help us understand more about their age and reproductive status.
Mare
A mare is an adult female horse, usually over the age of four. Mares are known for their nurturing nature and often play crucial roles in both riding disciplines and breeding programs. They’re the matriarchs of the horse world!
Gelding
A gelding is a male horse that has been castrated. This process typically makes them more even-tempered and easier to handle than stallions. Geldings are popular choices for riders of all levels because of their calm and reliable demeanor. Most of my riding school horses here at Willowbrook are geldings.
Stallion
A stallion is an intact (not castrated) male horse over four years old. Stallions are often admired for their strength and spirit but can be more challenging to manage due to their natural instincts. They are commonly used for breeding purposes to pass on desirable traits.
Other Horse Gender Terms
Beyond the main gender terms, there are other gender-related terms you might come across in the horse world. These terms often relate to age or specific roles in breeding and can give you more insight into a horse’s background or purpose.
Foal
A foal is a young horse of either gender that’s less than one year old. These little ones are full of energy and curiosity as they explore the world and learn from their mothers.
Filly
A filly is a female horse under the age of four. As they grow, fillies begin training and learning the skills they’ll need as adult horses, whether that’s racing, jumping, or simply being a delightful companion.
Colt
A colt is a male horse under the age of four. Like fillies, colts are in training and full of youthful exuberance. They might be groomed for future roles as riding horses or, occasionally, as breeding stallions.
Weanling
A weanling is a young horse that has recently been weaned from its mother, usually around six months old. This term applies to both genders and marks the foal’s first step towards independence.
Yearling
A yearling is a young horse between one and two years old, regardless of gender. Yearlings are still growing and developing, but they’re beginning to look more like adult horses as they mature.
Stud
A stud refers to a stallion used specifically for breeding. The term can also denote a breeding farm, as in “stud farm,” where stallions and mares are brought together.
Broodmare
A broodmare is a mare that is used for breeding purposes. These mares are selected for their excellent traits, such as good temperament or athletic ability, which they can pass on to their offspring. Broodmares are the cornerstone of any breeding program.
Rig
A rig, also known as a ridgling or cryptorchid, is a male horse with one or both testicles undescended. Rigs can exhibit stallion-like behavior and may require special veterinary care. Understanding this term is important for proper horse management and health.
FAQs
Can mares and geldings be kept together?
Yes, mares and geldings are often kept together and typically get along well. Since geldings are castrated, they’re less likely to show aggressive or mating behaviors, making mixed-gender groups manageable.
What’s the difference between a stud and a stallion?
A stallion is an intact male horse, while a “stud” is a stallion that is actively used for breeding. The term “stud” can also refer to a breeding farm.
Why are many riding horses geldings?
Geldings are popular as riding horses because they’re typically calmer and easier to manage than stallions, which can be more territorial or aggressive. Gelding reduces hormonal behaviors, making them safer and more predictable for various riding disciplines.
Do fillies and colts behave differently as they grow?
Yes, fillies (young females) and colts (young males) can exhibit different behaviors. Colts may show more boisterous or assertive behavior due to developing hormones, while fillies can display more reserved or cooperative behavior.
