What Is a Filly Horse? Age & Gender

Ever found yourself wondering what exactly a filly horse is? 

Understanding the term can be quite straightforward once you know the basics. Here at Bet442, we’ll dive into the age and gender specifics that define a filly horse. Stick around to become more knowledgeable about this fascinating equine terminology.

What Is a Filly In Horse Terms?

In horse terms, a filly refers to a young female horse. Specifically, this term is used to describe a female horse that is under four years old. After reaching the age of four, she is then referred to as a mare.

It’s important to know that the classification depends purely on age and gender. For racing and breeding purposes, distinguishing between fillies and mares helps in organising competitions and understanding the horse’s development stages.

Additionally, recognising a filly’s stage of growth can provide insights into her physical and behavioural characteristics, which may differ from those of older horses or males.

Filly Horse Gender & Age

A filly is a term specifically used in horse racing and breeding to define a young female horse. To be classified as a filly, the horse must be female and under four years old.

In simpler terms, filly is just a designation of age and gender. Once a female horse reaches the age of four, she is then known as a mare. This distinction helps in various aspects of horse racing and breeding, ensuring clear communication and understanding.

Understanding the term’s significance can also be valuable for those interested in horse racing, as different competitions may have categories based on the horse’s age and gender.

Being aware of these categories can improve your knowledge and appreciation of the sport.

Filly vs Colt: What’s The Difference?

When delving into horse terminology, it’s important to distinguish between a filly and a colt.

A filly is a young female horse under the age of four. On the other hand, a colt is a young male horse, also under four years old. After reaching four years, a colt is often called a stallion if left intact, or a gelding if castrated.

Understanding these terms is essential for anyone interested in horse racing or breeding. Knowing whether a young horse is a filly or a colt can help you better appreciate their development and the specific categories they may race in.

How Does a Filly Become a Mare?

A filly becomes a mare simply with the passage of time. Once a female horse reaches the age of four, she is no longer referred to as a filly. Instead, she gains the title of mare.

This transition is based purely on age. The change from filly to mare does not involve any specific physical or behavioural changes, though older horses may naturally be more experienced or trained in certain activities.

In horse racing and breeding, knowing at what point a filly becomes a mare is essential for understanding categories and eligibility for different races or breeding purposes. The distinction helps to ensure that horses compete against others of similar age and development stages.
