Pregnant Mare Leaking Clear Fluid

Pregnant mares may leak clear fluid from their vulva during the latter stages of pregnancy. This is known as ‘waxing’ and is most common within two to three weeks of their due date. The fluid is typically clear but can sometimes be tinged with a slight yellow hue or contain traces of mucus.

It often has a sweet smell and should not have any odor that could indicate infection or illness in the mare. If there are any changes in color, smell, or amount of discharge, it’s important to contact your veterinarian right away, as this could be an indication of pre-term labor or other health concern related to the pregnancy.

If you have a pregnant mare, it is important to be aware of the signs that she may be leaking clear fluid. This can indicate that the foal is preparing for delivery and should not be ignored. If your mare’s udder begins to swell or if you notice any damp spots on her underside, this could mean she is leaking colostrum or amniotic fluid.

This can happen anywhere from two weeks before labor up until right before birth and is a sign that it’s time to get ready for the big day! If you went to know more about pregnant mare leaking clear fluid, keep reading!

Why is My Mare Leaking Clear Fluid?

If your mare is leaking clear fluid, it may be due to a condition known as “clear mucus discharge,” which occurs when the uterus becomes irritated and produces an excessive amount of clear mucus. This can be caused by a variety of things, including infection, hormonal imbalance, or simple irritation from over-exertion or trauma. If left untreated, this type of discharge can lead to serious health complications for your mare.

It’s important to have her examined by a veterinarian so they can accurately diagnose the cause and provide appropriate treatment. Treatment often includes antibiotics and anti-inflammatory medications along with rest and proper nutrition to help restore balance in the body. In some cases, surgery may also be necessary in order to remove any blockages that could be causing irritation or infection.

What is the Clear Fluid from Pregnant Mares Teats?

The clear fluid from pregnant mares teats is known as colostrum, and it is a thick, yellowish liquid produced in the first few days after foaling. This fluid contains antibodies that can protect the newborn foal against infection and disease. Colostrum also provides essential nutrients to help support the growth and development of the young foal.

It helps stimulate motility of the gastrointestinal tract, which aids in digestion, absorption, and utilization of food nutrients by providing immunoglobulins (IgG), enzymes, proteins, vitamins, minerals, and other components necessary for healthy development.

Does a Mare Have Discharge Before Foaling?

Yes, a mare will typically have discharge before foaling. This is usually clear or white in color and may be quite watery. It can also appear as an accumulation of thick mucus-like material around the vulva and tail head area.

The discharge may start up to 24 hours before the birth and increase in amount as the time for foaling approaches. Paying attention to signs such as this can help you anticipate when your mare is about to give birth.

How Long Does a Mare Start Dripping Milk Before Foaling?

Mares usually start to drip milk anywhere from 2-7 days prior to foaling. During this time, the mare’s udder will become increasingly swollen and full of milk, making it easier for her to nourish her newborn shortly after birth. This is an important signal that a mare is close to giving birth and requires careful monitoring by owners or veterinarians.

If a mare has not started dripping milk within seven days of the expected foaling date, it could be an indication of potential health issues with the pregnancy, and professional veterinary advice should be sought immediately.

Pregnant Mare Behavior

Pregnant mare behavior can vary significantly depending on the stage of their pregnancy. During the early stages, they may be more alert and energetic than usual, as well as display increased appetite levels. In later stages of pregnancy, however, mares may become more lethargic due to carrying additional weight and developing a larger abdominal area.

It is important for owners to provide extra support during this period by offering adequate nutrition and plenty of rest.

Pregnant Mare Keeps Lifting Tail

When a pregnant mare lifts her tail, it is often the first sign that she is in labor. This behavior can be seen when contractions start, and the horse will lift her tail as a way to help pass the foal through the birth canal. It is important for owners of pregnant mares to watch out for this behavior and contact their veterinarian if they see it occurring.

Pregnant Mare Udder Development

Mare udder development during pregnancy can be an indicator of how close the mare is to giving birth. As the mare gets closer to her due date, the teats will begin to swell and fill with milk in preparation for foaling. The size and shape of the udder may also change slightly as colostrum production begins; colostrum is a nutrient-rich fluid that contains antibodies that are important for newborn foal health.

Mare Dripping Milk Not Pregnant

Mare dripping milk is a condition in which lactation occurs despite the mare not being pregnant. This is usually due to hormonal imbalances or excessive pituitary stimulation and can occur at any time of year with no signs of pregnancy present. Treatment for this condition may include hormonal balancing medications and avoidance of stressors that could trigger further production.

In some cases, surgical removal of the mammary glands may be necessary in order to stop lactation completely.

Normal Mare Non-Pregnant Mare Teats

Normal mare teats consist of two glands per side, located beneath the skin in the area just below her abdomen. Each gland has an opening for milk to flow through and is referred to as a “teat cistern.” The number of openings can vary between breeds, but typically each teat has two orifices.

In non-pregnant mares, these teats will not be enlarged or filled with fluid as they may be during lactation. It is important that a mare’s udder stays clean and dry at all times, which helps maintain good health and prevents infection.

Do Mares Teats Swell When in Season

Mares typically experience a period of heat or estrus every 21 days, and during this time, their teats may swell as they prepare to lactate. This swelling is caused by an increase in hormones and the mare’s body preparing for a potential pregnancy. Swelling is not painful but can be uncomfortable for the mare, so it’s important to monitor her closely during these times and provide extra care if needed.

Horse Udder Swollen on One Side

A horse udder swollen on one side could be a sign of several medical issues, including mastitis, an infection of the udder that can cause pain and discomfort. If you notice your horse’s udder is swollen on only one side, it is important to consult with your veterinarian so they can diagnose and treat the issue as soon as possible.


This blog post has explored the common occurrence of pregnant mares leaking clear fluid. It is important to note that this should not be cause for alarm, as it is a normal part of the pregnancy process and does not indicate any kind of health problem with the mare or her foal. However, if your pregnant mare is displaying other signs of distress, such as increased discharge, decreased appetite, or general lethargy, then you should contact your veterinarian immediately.

No matter what, though, always keep an eye out on your pregnant mare and ensure she receives regular check-ups throughout her term to ensure her safety and that of her unborn foal. Thank you for reading our post about pregnant mare leaking clear fluid.
