Why do mares kick or squirt when in heat?

Introduction to Mares in Heat

Mares, like most female mammals, undergo a reproductive cycle known as the estrus cycle. During this cycle, they experience hormonal changes that make them receptive to breeding. Mares in heat can display a range of behaviors that may seem unusual or even alarming to their owners.

Understanding the estrus cycle and the behavioral changes that accompany it can help horse owners anticipate and manage these behaviors, ensuring the safety and well-being of both horse and handler.

The Estrus Cycle: What Happens to Mares?

The estrus cycle of a mare typically lasts 21-23 days and is characterized by a series of hormonal changes that prepare the mare for breeding. During the cycle, the mare’s ovaries produce and release eggs, and her uterus undergoes changes to support pregnancy.

The estrus cycle is divided into several phases, including proestrus, estrus, metestrus, and diestrus. The most noticeable behavioral changes occur during the estrus phase, also known as “heat.” During this phase, the mare may exhibit a range of behaviors, including restlessness, vocalization, and a heightened interest in other horses.

Behavioral Changes in Mares During Estrus

Mares in heat may display a range of behaviors that can be challenging for their handlers. These behaviors can include restlessness, vocalization, increased aggression, and a heightened interest in other horses.

One of the more common behaviors associated with mares in heat is kicking. Mares may kick at other horses or objects, including their handlers. This behavior can be dangerous and requires careful management.

Why Do Mares Kick When in Heat?

Mares kick when in heat for a variety of reasons. One common reason is that they are responding to the discomfort or irritation of having their reproductive organs touched or manipulated. This can occur when a veterinarian is performing a reproductive exam or when a stallion is attempting to breed with the mare.

Another reason mares may kick when in heat is that they are attempting to establish dominance over other horses. Mares in heat may become more aggressive and territorial, particularly towards other mares.

Understanding the Kicking Behavior of Mares

To understand why mares kick when in heat, it is important to consider the context in which the behavior occurs. Kicking can be a natural response to discomfort or irritation, but it can also be a learned behavior that is reinforced when the mare is successful in driving away a perceived threat.

It is also important to consider the individual mare’s temperament and past experiences. Some mares may be more prone to kicking than others, and past negative experiences can contribute to a mare’s tendency to kick.

Common Triggers of Kicking in Mares

Several factors can trigger kicking behavior in mares. These can include pain or discomfort in the reproductive organs, fear or anxiety, and attempts by other horses to breed with the mare.

Handlers should be especially cautious when performing reproductive exams or handling mares in heat, as these activities can trigger kicking behavior.

How to Manage Kicking Behavior in Mares

Managing kicking behavior in mares requires a combination of training, management strategies, and, in some cases, veterinary intervention. Handlers should work with their veterinarian to ensure that the mare’s reproductive health is being properly managed, and any underlying medical issues are being addressed.

Training techniques, such as desensitization and positive reinforcement, can also be effective in reducing kicking behavior in mares. Handlers should avoid punishing or reinforcing the behavior, as this can make it worse.

Why Do Mares Squirting Urine When in Heat?

Another behavior commonly associated with mares in heat is the squirting of urine. This behavior, known as “winking,” is caused by contractions in the mare’s reproductive tract and is a sign of sexual arousal.

Mares may also squirt urine as a way to signal their receptiveness to breeding to other horses.

Understanding the Urine-Squirting Behavior of Mares

Mares squirting urine when in heat is a natural behavior that is a sign of sexual arousal. While it may seem unusual or even alarming to some handlers, it is not typically a cause for concern.

However, if a mare is excessively squirting urine or is experiencing other symptoms of reproductive issues, such as discharge or discomfort, veterinary intervention may be necessary.

Conclusion: Dealing with Mares in Heat

Mares in heat can be challenging for their handlers, but understanding the behavioral changes that accompany the estrus cycle can help manage these behaviors effectively.

Handlers should be vigilant in managing kicking behavior and should work with their veterinarian to ensure that their mare’s reproductive health is being properly managed. With proper training, management strategies, and veterinary care, mares in heat can be safely and effectively managed.
