How Long Can A Mare Delay Labor

**How Long Can a Mare Delay Labor?**

If you’re a horse owner or breeder, you may find yourself wondering, “How long can a mare delay labor?” It’s a valid question, as the duration of labor in mares can vary. While most mares give birth within 10-15 minutes after their water breaks, there are instances when labor can be delayed for several hours or even a day. In this article, we will explore the factors that can cause labor delay in mares and what you can do to help them.

Causes of Labor Delay in Mares

There are several factors that can contribute to labor delay in mares. Understanding these factors is crucial in managing and assisting the mare during labor.

Inexperienced Mares

First-time or inexperienced mares may take longer to go into labor and deliver their foals. This is because their reproductive systems are not yet fully developed, and they may require more time to prepare for giving birth. It’s important to be patient and vigilant when dealing with an inexperienced mare, as they may need assistance or intervention if labor is excessively delayed.


Stress can have a significant impact on a mare’s ability to go into labor and deliver her foal. Factors such as changes in environment, transportation, or noisy surroundings can all contribute to stress. If a mare feels threatened or insecure, her body may delay labor as a protective mechanism. It’s essential to create a calm and comfortable environment for the mare, especially during the final stages of pregnancy, to minimize stress and promote a timely delivery.

Hormonal Imbalance

Hormonal imbalances can disrupt the normal progression of labor in mares. The release and regulation of hormones, such as oxytocin and prostaglandins, play a crucial role in initiating and sustaining labor contractions. If there is an imbalance in these hormones, it can lead to a delay in labor. Consulting with a veterinarian to assess and address any hormonal issues is vital for a successful foaling.

Positional Abnormalities

Sometimes, a foal’s position or presentation in the birth canal can cause labor delay. A foal in an abnormal position, such as breech or transverse, may face difficulties in passing through the birth canal and initiate labor. These positional abnormalities can prolong the birth process and may require intervention to correct the position of the foal and facilitate delivery.

Assisting the Mare in Labor

While it’s crucial to allow nature to take its course during labor, there may be instances when intervention becomes necessary. Here are some ways to assist a mare experiencing labor delay:

Veterinary Assistance

If a mare is significantly overdue or showing signs of distress, it’s essential to contact a veterinarian for assistance. A veterinarian can perform an examination to determine the cause of labor delay and recommend appropriate interventions. They may administer medications to stimulate contractions or help reposition a foal if necessary.

Provide a Calm and Quiet Environment

Creating a calm and quiet environment for the mare during labor can help alleviate stress and promote a more natural progression of labor. Minimize disturbances and loud noises, ensuring the mare feels safe and secure. This comfortable atmosphere can help stimulate the release of hormones necessary for labor to progress.

Physical Support

In some cases, physically supporting the mare during labor can be beneficial. This can include gently guiding or repositioning the foal, providing counter-pressure during contractions, or assisting with manually breaking the amniotic sac if it hasn’t ruptured naturally. However, it’s crucial to have prior knowledge and experience in assisting with equine labor or seek professional help to avoid causing harm to the mare or foal unintentionally.

Frequently Asked Questions

Now, let’s address some frequently asked questions regarding labor delay in mares:

Q: How long is labor supposed to last in mares?

A: On average, the duration of labor in mares can range from 10-30 minutes after the water breaks. However, it is not uncommon for labor to be delayed for several hours or even a day in some cases.

Q: Can labor delay be dangerous for the mare and foal?

A: Labor delay can be potentially dangerous for both the mare and foal. Prolonged labor can lead to exhaustion and fatigue in the mare, increasing the risk of complications. Additionally, the foal may experience distress or oxygen deprivation if the labor is excessively delayed.

Q: When should I seek veterinary assistance for labor delay?

A: If a mare has been in labor for an extended period, such as several hours without any progress, or if she shows signs of distress or abnormal behavior, it’s crucial to contact a veterinarian for assistance. They can assess the situation and provide appropriate interventions if necessary.

Final Thoughts

Labor delay in mares can be a cause for concern, but it’s essential to remain calm and patient during the birthing process. Understanding the various factors that can contribute to labor delay and knowing when to seek assistance can make a significant difference in the health and well-being of the mare and foal. By providing a supportive and stress-free environment, along with timely veterinary intervention if needed, you can help ensure a safe and successful foaling experience.
