Welcoming a new foal into the world is an exciting journey for any horse owner. However, caring for a pregnant mare can feel overwhelming, especially if you’re unsure what to expect. From spotting early signs to ensuring your mare stays healthy throughout her pregnancy, understanding the process is key to supporting her and her unborn foal. Let’s explore the signs, stages, and essential care tips for your pregnant mare.

🩺 Vet Recommendations

Pregnancy in mares, or gestation, typically lasts around 11 months, or 340 days on average. During this time, your mare’s health and nutrition are critical to her well-being and the development of the foal. Proper prenatal care can reduce complications and set the stage for a healthy delivery.

Here are some general veterinary recommendations for managing a pregnant mare:

  • Schedule regular veterinary check-ups to monitor the mare’s health and the foal’s development.
  • Ensure your mare is up to date on vaccinations, especially rhinopneumonitis (equine herpesvirus) at 5, 7, and 9 months of pregnancy.
  • Provide proper nutrition, including quality forage and any recommended supplements.
  • Maintain a clean and safe environment to minimize stress and prevent injuries.

With a solid care plan, you can help your mare navigate her pregnancy safely.

⚠️ What to Watch For

Recognizing the signs of pregnancy in a mare can sometimes be tricky, especially during the early stages. Some mares may not show obvious physical changes until later in gestation. Here are key signs to look for:

  • Changes in behavior, such as increased calmness or irritability.
  • Weight gain and a noticeable enlargement of the abdomen over time.
  • Development of the udder, typically in the last month of pregnancy.
  • Milk secretion or “waxing” on the teats in the final weeks or days before foaling.

If you suspect your mare is pregnant, a veterinarian can confirm this through ultrasound or hormone testing as early as 14–16 days post-breeding.

📋 Care Tips

Caring for a pregnant mare requires attention to her unique needs at each stage of pregnancy. Here’s how you can support her throughout the journey:

Early Pregnancy

During the first few months, the focus should be on maintaining your mare’s general health. Continue her regular diet and exercise routine, but avoid excessive stress or strenuous activities.

Mid-Pregnancy

As the pregnancy progresses, your mare will need additional calories and nutrients to support the growing foal. Ensure she has access to high-quality hay, and consult your vet about adding grain or supplements if needed. Regular deworming and dental care are also essential during this stage.

Late Pregnancy

In the final trimester, your mare’s energy and nutritional needs will increase significantly. Transition her to a specialized mare and foal feed if recommended by your vet. Limit intense exercise but allow for light movement to promote circulation and muscle tone. Begin preparing a clean, quiet foaling area well in advance of her due date.

✅ Do’s and Don’ts

Here are some additional do’s and don’ts to keep in mind when caring for a pregnant mare:

  • Do provide free access to fresh, clean water at all times.
  • Do monitor her closely for any signs of discomfort or illness.
  • Do consult your vet about any changes in her diet or routine.
  • Don’t expose her to other horses that may carry infectious diseases.
  • Don’t overfeed, as excessive weight gain can lead to complications.

By following these guidelines, you can help ensure a smooth and healthy pregnancy for your mare.

💡 Expert Advice

Every pregnancy is unique, and it’s important to tailor your care to your mare’s individual needs. Work closely with your veterinarian to develop a care plan that supports both your mare and her foal. Regular communication with a trusted vet can help you address any concerns early and ensure the best outcome for your mare’s pregnancy.

As the foaling date approaches, familiarize yourself with the signs of labor and be prepared to assist if needed. While most mares deliver without complications, knowing when to call a vet can make all the difference in an emergency.

FAQs

Q: How can I tell if my mare is in labor?
A: Signs of labor include restlessness, sweating, frequent urination, and lying down and getting up repeatedly. During the second stage of labor, you’ll notice strong contractions and the appearance of the foal’s front legs.

Q: Should I separate my pregnant mare from other horses?
A: Yes, it’s a good idea to separate your mare from other horses in the final weeks of pregnancy to reduce stress and prevent injury. Provide her with a quiet, clean space where she feels safe.
