What Does A Pregnant Horse Look Like? (Question)

Tell-tale tummy. Perhaps the most obvious sign of pregnancy is a swollen abdomen, and this is of course a good indication, however mares do not always have an overly enlarged belly. The gestation period itself is almost a year, therefore mares can retain their normal shape well into their pregnancy.


  • One of the latest signs that your horse is pregnant will be changes to her udders. A few weeks before your mare foals, you will begin to notice her udders fill with milk. There may be other visible changes to the appearance of her udders and teats as she nears delivery.

When does a horse start showing pregnancy?

After about three months the foal will be developing rapidly and start to look like a small horse. After about six months, the mare may start to be visibly pregnant. Mares that have foaled before may show an expanding belly sooner than a maiden mare.

How can you tell if your horse is pregnant at home?

8 Signs That Your Horse is Pregnant

  1. Absence of An Estrus Cycle May Indicate a Horse Is Pregnant.
  2. Changes in Behaviour & Responses Can Indicate Pregnancy.
  3. Elevated Progesterone Levels Are a Sign a Horse Is Pregnant.
  4. Bloated Stomach Can Be a Sign of Pregnancy.
  5. Changes to Mare’s Udders Can Indicate a Horse Is Pregnant.

Will a pregnancy test work on a horse?

The small size of miniature horses makes it impractical to pregnancy test them by traditional methods used for full-size mares such as manual palpation via the rectum, or with ultrasound technology using a rectal probe.

How do you tell if your mare is having a colt or filly?

On an open mare (or a gelding) the nail is not supposed to move. On a mare that is going to have a stud colt, the nail will swing back and forth in a straight line. If she’s going to have a filly, the nail will swing around in a circular motion.

How do you know if a horse is about to give birth?

The visual signs of a mare’s readiness to foal are:

  • Udder distension begins 2-6 weeks prior to foaling.
  • Relaxation of the muscles of the croup 7-19 days prior to foaling; relaxation around the tail head, buttocks, and lips of the vulva.
  • Teat nipples fill 4-6 days prior to foaling.
  • Waxing of the teats 2-4 days before.

Can a mare be pregnant and not look pregnant?

Mares that are pregnant have a roundness and a palpable springiness to their abdomen. The mammary glands should develop starting at 4-6 weeks before due date. However, mares that have had multiple foals may look pregnant even when they are not. The equine pregnancy is 330-400+ days.

How far along is my pregnant mare?

A typical adult horse female (mare) goes into labor (foals) around 330-345 days after mating. As we can see, the average horse pregnancy length is equal to 338 days (that is, a little over 11 months ). However, we need to remember that large horses’ pregnancies tend to last longer than the ones of tiny ponies.

How much does it cost to see if a horse is pregnant?

If no pregnancy is detected, she should be coming back into heat very soon and you can repeat the expenses from that point to try again. Plan for about $100-$125 for the pregnancy check cost, and then another subsequent check of the same expense at about 30 days to confirm the heartbeat.

Can you use a fetal Doppler on a horse?

Due to substantial differences in fetal anatomy, MCA cannot be visualized in the equine fetus, but the carotid artery, from which MCA originates, can be assessed by Doppler ultrasonography at multiple sites, including the internal carotid branch, in close proximity to where MCA branches off.

Will a pregnant mare accept a stallion?

Yes, a pregnant mare will sometimes allow a stallion to mount.

What to Expect When Your Mare is Expecting

The basics of equine reproduction and horse pregnancy include mating, the horse gestation period, and foaling, to name a few concepts. A mare (a female horse) may only give birth to one foal every calendar year. It is possible for a mare to start producing afoalat when she is 18 months old, but it is healthier if the mare is at least four years old since she will have grown to her maximum size by then. After her twenties, a mare may continue to have offspring into her thirties again. Despite the fact that horses may mate and give birth without the assistance of a veterinarian, many issues can be avoided by having the stallion assessed before breeding and the mare checked and cared for appropriately during the pregnancy.

Average Gestation Period

When it comes to horses, the gestation period is normally between 330 and 345 days, or 11 months. A breeder’s ability to recognize if a mare is more likely to foal earlier or later than the norm is essential for success in the breeding industry. Ponies have a shorter gestation time than horses, which is typical. A natural environment is one in which the stallion will breed the mare throughout the summer months, and the foals will be born the following year, often during the spring and early summer months.

Mastiff mares are classified as seasonally polyestrous, which indicates that they go into heat (estrus) and are receptive to a stallion at regular intervals during the spring and summer.

Breeders that seek to modify the reproductive cycle in order to have foals born earlier in the year (as is routinely done in the Thoroughbred racehorse industry) will employ artificial illumination to replicate the longer days of spring and summer, rather than natural lighting.

This enables mares to be mated earlier in the year, resulting in a foal being born sooner the following year.

Checking For Pregnancy

Mares may not display any obvious indicators of pregnancy during the first three months of their pregnancy, other from the absence of an estrus cycle. After about two weeks have passed since the breeding event, an ultrasound can be used to confirm the pregnancy. Two to three months after conception, blood and urine tests can be performed to confirm the pregnancy. If the mare is six weeks into her pregnancy, a veterinarian may be able to personally feel the little embryo in her uterus via rectal palpation.

Horse twins are extremely unusual, yet they have the potential to cause the mare to miscarry.

As a result, it is frequently suggested to “pinch off” one embryo at a time.

It is not uncommon for a mare to miscarry her pregnancy, and it is advised to repeat an ultrasound, blood, or urine test after around three months.

Things like seeing how a mare shakes her head, the expression in her eyes, or the way a needle moves when held over her tummy are not reliable indicators of whether or not she is in foal.

Later Stages of Gestation

By the time the foal is three months old, it will be growing swiftly and beginning to resemble a miniature horse. After around six months, the mare may begin to show signs of pregnancy. Mares that have already given birth may exhibit signs of an enlarged stomach sooner than a virgin mare. With each passing month, the mare’s belly will continue to swell in anticipation of the foal’s due date in the spring of 2019. The mare’s udder will begin to grow and begin to produce sticky yellowish fluid around two weeks before the due date of the baby.

  • If the yellowish fluid is allowed to ferment, it will transform into the first milk or colostrum.
  • It is possible that her stomach will appear to lower as the foal aligns itself for delivery.
  • The mare will look restless shortly before giving birth, and she may paw the ground and examine her flanks (similar tocolic symptoms).
  • The mare may lie down and rise up several times, but she will give birth while lying down on the ground.
  • At this point, the foal is usually born within a few minutes of being born.
  • The mare or foal may sustain an injury or develop another problem during the birthing process, and this will require expert assistance.
  • If you have any reason to believe your pet is unwell, contact your veterinarian immediately.

How to Tell if Your Mare is Pregnant and Why It’s Important

By the time the foal is three months old, it will be growing swiftly and beginning to resemble a tiny horse. The mare may begin to show signs of pregnancy after around six months. Compared to a virgin mare, a horse that has previously given birth may exhibit signs of a growing belly sooner. With each passing month, the mare’s belly will continue to swell in anticipation of the foal’s due date in the spring. The mare’s udder will begin to grow and to produce sticky yellowish fluid around two weeks before the due date of the pregnancy.

  1. If the yellowish fluid is allowed to ferment, it will eventually develop into the first milk or colostrum.
  2. In preparation for giving delivery, her stomach may appear to decrease.
  3. It is common for the mare to get restless in the weeks before giving birth, pawing the ground and checking her flanks (similar tocolic symptoms).
  4. The mare may lie down and get up several times, but she will give birth while lying down on the floor.
  5. When the foal is thus young, it is usually born within a few minutes.
  6. The mare or foal may sustain an injury or develop another problem during the birthing process, and this will require expert assistance.
  7. If you have any reason to believe your pet is unwell, contact your veterinarian immediately for advice and treatment.

Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet’s needs and circumstances.

How to Tell If Your Mare is In Foal and Why It’s Important

In order to be certain your mare is in foal and that the pregnancy is healthy, you must have her inspected by a veterinarian, ideally one who has experience with horse reproduction in general. Approximately fourteen to eighteen days after the mare has been bred, this procedure should be carried out. The veterinarian can now establish whether or not the mare is pregnant twins at this time. Re-absorption and spontaneous abortions in horses are caused by twin pregnancies, which are a common occurrence.

Despite the fact that it appears harsh, the likelihood of a mare successfully delivering vigorous twin foals is quite low.

Because you’ll know whether or not the pregnancy is healthy early on and how far along it is, you’ll be able to tell if things are proceeding properly or if there are indicators that an abortion may be necessary.

Care and Feeding for Pregnant Mares

You want to know whether your mare is in foal as soon as possible since your feeding and management of her care may need to vary somewhat if she is. The best hay or pasture, as well as salt and minerals, will be necessary for your mare’s nutritional needs. If your pasture grass contains fescues, you may want to consider removing the mare and allowing her to graze somewhere else instead. In order to protect your mare from pasture bullies who might damage her and make the foaling process more difficult for her, you may wish to isolate her from them.

The development of the fetus can be affected by some immunizations and parasite control drugs.

Having your mare thoroughly inspected by a veterinarian does cost money, but the expense is insignificant when compared to the entire cost of raising a foal—or the cost of losing a foal or the mare in the first place.

It is true that rearing a foal might be one of the more expensive methods of producing another horse!

Improper Assumptions About Mare Pregnancy

  • People have a tendency to believe that nature will take care of everything. This does not always result in the greatest possible conclusion. Preventing potential health concerns that might impair the reproductive health of your mare, as well as the health and longevity of your foal, can be accomplished by providing correct care early in the pregnancy. There are a variety of traditional ways for determining whether or not your mare is carrying a foal. To determine whether your mare is pregnant, you should not place a threaded needle, ring, nail, or string on her tummy. This is not a reliable means of establishing whether your mare is pregnant. Another technique involves paying attention to how the mare shakes. It indicates that she is in foal if she shakes only her head and neck and not her entire body. It is hypothesized that mother is protecting her foal by not moving it too much. They are not accurate
  • The absence or presence of a heat (estrus) cycle is also not a reliable sign of pregnancy in women. Despite the fact that they are in foal, some mares will appear to be going through a heat cycle. Some mares, particularly during the fall and winter months, may not exhibit an evident heat cycle
  • Nevertheless, this is not uncommon. It is hard to tell whether or not a mare is pregnant early on merely by looking at her. Some mares, particularly those who have never given birth to a foal, may not’show’ at all during the pregnancy. Others have a well-sprung barrel that makes them appear to be in foal all of the time, which is not the case. Because they’ve had multiple foals in the past, or because the mare has a hay belly that causes her tummy to seem swollen, this may be the case. Even late in the pregnancy, not all mares exhibit clear indicators of being in labor or bearing a foal. It is possible that some mares will appear fatter and have milk pouring down their back legs for several weeks before giving birth, while others will not. Some will show extremely obvious indicators that they are in or about to foal, while others will show no signs at all. There have been instances in which a mare’s owner was completely unaware that the mare was in labor until the foal was born.

If you have any reason to believe your pet is unwell, contact your veterinarian immediately. Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet.

Six Signs That Your Horse Might Be Pregnant

The 5th of August, 2015, is a Wednesday. Breeding horses is a really fulfilling experience, and whether you are breeding for profit or for pleasure, it is critical that you be aware of the symptoms to watch for in a foaling mare in order to provide your horse with the care it need throughout pregnancy. In horses, the typical pregnancy period can last between 320 and 362 days, with ponies having shorter gestation periods than horses.

The majority of mares will give birth within 330-345 days following a successful conception; however, even if a mare is an experienced broodmare, it is not always simple to discern if she is pregnant. Continue reading to learn about the six symptoms that your mare could be pregnant:

i. Moody mares

It is possible to determine whether your mare has conceived by returning her to a stallion for two weeks after covering and seeing how she behaves. The probability that she is not in foal is increased if she is attentive to the stallion, displays her rear and raises her tail like she does during heat. It is true that refusing to be sired does not always result in pregnancy, but most mares who have conceived will refuse to accept the overtures of a stallion if he approaches them.

ii. Heat rising

Because mares are polyestrous (go into heat several times a year), they are only ever in heat when they are in heat during the breeding season, which is often in the spring and summer. In general, she goes through a heat cycle every 21 days, during which she will display indications like as raising her tails while in touch with geldings, opening and shutting her vulva, and occasionally squirting pee. If your mare is displaying these indicators, it is doubtful that she is pregnant; nevertheless, there is such a phenomenon as silent heat, which occurs when a mare ovulates as usual but will not stand for a stallion to cover her during her period.

iii. Tell-tale tummy

A big abdomen is perhaps the most evident indicator of pregnancy, and this is, of course, a favorable signal; nevertheless, mares do not always have an excessively enlarged stomach. Because the gestation period is over a year long, mares can maintain their usual form for the duration of their pregnancy.

iv. Shake it off

The hypothesis of shaking is one of the most common wives’ stories for verifying a mare’s pregnancy, and it has been around for quite some time. When a mare is pregnant, it is believed that she will simply shake her head and neck, rather than her entire body, in order to protect her unborn foal.

v. Feeling fine

A veterinarian can discover signs of horse pregnancy through a rectal examination performed on the animal. If done within three weeks of the mare’s covering, the vet will insert his hand in the rectum to palpate the uterus and assess its size, shape, and whether or not the ovaries have swollen in any way.

vi. Scan to be safe

An ultrasonic scan is the only method to be absolutely confident that a successful covering has been performed. This procedure can be performed by a veterinarian as early as 16 days into the pregnancy to identify the presence of a heartbeat, although it is more commonly performed between 55 and 70 days to confirm the gender of the foal.

Is Your Horse Pregnant? 8 Clear Signs to Tell

Posted at 7:45 a.m. hinHealth,Horse Care,Horse Training No matter if you’re breeding your horse to make money or for enjoyment, the process can be both demanding and rewarding. It is critical to be aware of some of the most frequent indicators that your horse has conceived in order to continue to offer them with the best possible care throughout the course of their pregnancy. What is the best way to know whether a horse is pregnant? There are several symptoms that your horse is pregnant that you should be aware of.

The use of an ultrasound can be used to confirm a pregnancy as early as 2 weeks after conception, however many owners prefer to wait until the pregnancy is further along before paying for an ultrasound exam.

The more familiar you are with your horse’s regular habits and responses, the easier it will be for you to spot these frequent indicators of pregnancy in your horse.

8 Signs That Your Horse is Pregnant

A horse’s gestation period is normally between eleven and twelve months in length! As a result, it is possible that your horse will not show pregnant for several months, if at all. As a result, it is critical to notice some of the other indicators of pregnancy in order to make the necessary adjustments to your horse’s food, activity, and living conditions.

Absence of An Estrus Cycle May Indicate a Horse Is Pregnant

When your mare conceives, the lack of an estrus cycle is frequently one of the first signals you will notice that she is pregnant. In fact, the fact that your mare has not gone into heat during the first three months of her pregnancy may be the most telling evidence that she is pregnant. When you are breeding your horse, you should be paying great attention to their estrus cycle and keeping track of when your mare is in heat, among other things. When your horse becomes pregnant, you will be able to breed her as a result of this.

It is crucial to remember that some horses may continue to show indications of estrus even after they have given birth to a foal.

Changes in BehaviourResponses Can Indicate Pregnancy

Although this is by no means a scientific indicator, a change in your mare’s demeanor or responsiveness to stallions may be an indication that she is pregnant. In most cases, mares get cranky or flirty when a male horse comes close by, especially if she is in heat at the time. Your horse may be pregnant if you discover that she is uninterested in a male partner. As you get more familiar with your mare’s regular behaviors, you will be able to spot these shifts in behavior much more quickly and effectively.

It is possible that your mare will become irritable or restless as she proceeds through the late stages of her pregnancy.

Elevated Progesterone Levels Are a Sign a Horse Is Pregnant

Progesterone levels may also be measured by a blood test, which can indicate whether or not your horse is in heat. Throughout their pregnancy, the majority of mares will have high progesterone levels in their blood. This is simply one of a number of blood tests that an equine reproductive expert may run to establish whether or not your mare has conceived if she is pregnant. The results of blood testing are not always accurate, as mares who are not pregnant have been observed to exhibit increased levels of progesterone in their bloodstream.

Bloated Stomach Can Be a Sign of Pregnancy

When your mare is in foal, you may notice that her stomach begins to appear swollen, even if she appears to be in good health. Typically, however, you will not discover visual indications of pregnancy until at least six months after conception has taken place. It’s crucial to remember that, much like people, each mare will carry her foal in her own way, making each birth unique. However, although some mares may begin to show visual indications of pregnancy during the first several months of their pregnancy, others may not look pregnant to the untrained eye until only a few days before giving birth!

Several cases, in fact, have come to my attention in which the mare’s owner was unaware that she was pregnant until the mare was in active labor.

Changes to Mare’s Udders Can Indicate a Horse Is Pregnant

Changing udders will be one of the most recent indicators that your horse is pregnant, so keep an eye out for them. You will notice that your mare’s udders are filling with milk a few weeks before she gives birth to her babies. As she gets closer to giving birth, she may notice additional noticeable changes in the look of her udders and teats. For whatever reason, you missed the previous symptoms of pregnancy and now see these changes in your mare’s udders, you must call an equine reproductive veterinarian as soon as possible since your mare is only a few weeks away from becoming a mother.

Changes in Movements Can Indicate Pregnancy

Many equestrians feel that mares who are pregnant will modify their movements. While this is the least scientific technique of knowing if your mare is in foal, it is the most widely used. For example, they will refrain from making any rapid or abrupt movements. In an effort to safeguard the foal, it is also usual for a pregnant horse to avoid moving her body throughout the birthing process. It is critical to search for any other symptoms that your horse is pregnant in addition to the ones listed above.

It is also possible that your horse will appear sluggish during the first month of her pregnancy and the final few months before foaling.

After all, she is the one who is responsible for bearing the foal!

Ultrasound Scan Is The Best Indicator That a Horse Is Pregnant

To be certain if your mare is in foal, a veterinarian must do an ultrasound scan on her to determine whether or not she is pregnant. Even as young as two weeks after fertilization, this procedure might be performed. If you are confident in the various indicators of pregnancy that your mare has showed, you can also choose to delay doing the first ultrasound until several months following conception. During the fourth month of pregnancy, an ultrasound can reveal the gender of the foal. In order to avoid disappointment, many owners opt to wait until this point before requesting an ultrasound exam.

Lack of Clear Signs That a Horse Is Pregnant

Horse owners frequently find that their mare is in foal only a few hours before the foal is born, which is more common than you may think. Because some mares do not show many indicators of pregnancy, or because the owner does not anticipate pregnancy to be the reason of their mare’s unusual behavior, it is possible that the mare is not pregnant. While it is improbable that this would happen if you purposely bred your mare, it is crucial to be prepared for the potential. It’s also crucial to realize that false pregnancies in horses are rather prevalent, as is the case with humans.

The best course of action if your horse is experiencing one or more of these typical pregnancy indications is to have them evaluated by an equine reproductive specialist in order to ascertain their current reproductive status.

Caring for a Pregnant Horse

Despite the fact that horses in the wild have historically mated, carried, and delivered foals on their own, a little additional care and attention will guarantee that they remain healthy during their pregnancy. Many parts of your horse’s care will stay the same at the start of her pregnancy, as will be the case throughout her pregnancy. You may expect your horse to eat her regular feed, exercise as usual, and be ridden until she is around 6 months pregnant, with the exception of the first month.

  • The majority of horse reproductive specialists recommend that you maintain a modest level of exercise during the month following conception since those are the most essential weeks for the survival of the foal.
  • Daily exercise, on the other hand, should be continued because it is one of the most effective strategies to prepare her for a safe and fruitful birth.
  • The majority of foals acquire around one pound per day throughout the months leading up to their birth.
  • When your mare is pregnant, she is more vulnerable to sickness and disease than she would be otherwise.
  • While this might be taxing on you as the owner, it is unquestionably the most effective approach to safeguard the safety and health of your mare and her foal.

What You Should Know About Equine Pregnancy.

If this is your first mare to give birth to a foal and you do not have experienced aid to rely on in your family or community, get expert advice before making any decisions that might put both the mare and the foal in danger. The majority of horses give birth to single foals without incident, however mares who are pregnant with twins, those who have health difficulties, and horses that are bred at later ages are at higher risk of complications. Once a mare becomes pregnant, a veterinarian should do frequent ultrasounds during the pregnancy, as well as check blood tests throughout the pregnancy and right before birth – since anything may go wrong at any time during the process!

When you expect your mare to foal, it is critical to have a veterinarian on call, not only for the welfare of the mother, but also for the good of the foal.

Signs a horse is pregnant

  • She is consuming more calories and fluids than normal. It’s possible that your horse will have a different appetite. She may have restlessness and sleep less than usual, which might result in some concern in their attitude as a result of it. Her udders swell and begin to fill with milk
  • Changes in conduct and the ability to get quickly upset
  • She’s skipping her menstrual cycle
  • All sorts of horses are pregnant at some point, and the most prevalent indicator is when their bellies become more extended as a result of the growing size of the foal inside them. Later in the pregnancy, you will be able to see the foal moving around in her tummy.

Gestation period and stages of pregnancy.

Have you ever had a horse that you were convinced was pregnant, only to find out later that it wasn’t? You are not alone in your feelings! It is critical to understand what is typical during pregnancy and what can suggest a more serious problem. During their gestation period, horses are pregnant for around 11 months, which is divided into three parts. In a horse’s pregnancy, the first stage is defined as the period between conception and 60 days following ovulation. While the embryo is at this stage of development, it travels through the uterus and attaches itself to the uterine lining.

  1. You may notice a slight increase in hunger, but that is about all you will experience.
  2. Stage 2: The second stage of a horse’s pregnancy lasts from day 61 to day 270 and is the longest stage of the pregnancy.
  3. The foal is growing slowly yet steadily in its mother’s womb, but she is safe to ride at this point.
  4. Horses might find it difficult to maintain their condition at this period, so they must be well-fed and provided with a comfortable space to relax.

Colostrum, which is a thick, yellow secretion produced by mares during the third trimester of pregnancy and which includes antibodies that foals require to protect themselves, is produced.

Changes in your mare shortly before giving birth?

Horses begin to exhibit significant changes and behave in a different manner in the hours coming up to delivery of the foal. Here are some things to keep an eye out for as your horse gets closer to delivery:

  • Because of this, the mare’s behavior becomes increasingly agitated and apprehensive. Extraordinary perspiration on her flanks and neck
  • Twitching her tail repeatedly while glancing back at her tummy with an anxious expression on her face She’s pacing around her stall
  • Getting out of bed and getting back up
  • Urination that is both irregular and profuse
  • She is kicking at the inside of her stomach.

Labor progression in horses

Understanding labor in horses is a difficult concept to grasp. Horses go through distinct phases of labor, and being aware of these stages is critical for the safety of the mother and unborn foal, as well as the comfort of the horse during this time. Stage One: During the first stage of labor, the mare becomes agitated and kicks at her stomach. In addition, she lies down and gets up frequently, urinates excessively, and begins to sweat. While this stage is in progress, horses can wander around, but they appear to be in distress.

Stage Two: This is the stage in which the foal is released from the protection of its mother’s womb.

Stage Three: The placenta should be expelled within three hours of the foal’s birth, although it is usually considerably sooner, sometimes as soon as fifteen minutes, depending on the circumstances.

When a foal is born, you should expect to see the following during the first three hours after birth:

  • The foal stands within one hour
  • The baby feeds within two hours
  • It swallows colostrum from its mother (which contains antibodies). The placenta has been removed

What does a mare need after giving birth?

Typically, a mare doesn’t require much attention after giving birth; nonetheless, a horse owner should give the mare plenty of time to recuperate after the delivery and ensure that she has access to enough food and water to sustain herself. For her health and safety, she must get sufficient care throughout this period. She must be prepared not only for the delivery process, but also to prepare her body for future pregnancies. The first stage after birth is to determine whether or not there are any health issues with the foal that require immediate treatment.

It is vital for foals to consume colostrum as soon as they are born.

You should next examine how well the mare has recovered after ensuring that the foal is in good health.

While keeping an eye out for infection, you can rinse and brush her hair to keep it from matting.

You should seek medical assistance promptly if you detect anything odd, such as excessive or smelly discharge. The mare should be able to get up on all fours without too much trouble and walk about and move around with her new foal with a little more ease after a couple of days.

Riding your mare after she gives birth.

Before choosing when your mare will be able to return to work, take into consideration all of the aspects that have contributed to her complete recovery, including diet, exercise level, and general health state! It takes time for a woman to heal fully after giving birth; normally, two weeks off is sufficient. If you are unclear whether or not your horse is safe to return to work, speak with a veterinarian right away!

Breeding your mare after she gives birth.

Every year, the majority of horse breeders anticipate receiving a foal from their broodmares, and it is critical that they birth as early in the year as possible due to the normal registration requirements of most horse breed associations. When it comes to racehorse breeders, it’s extremely important to breed a mare as soon as possible after foaling since Thoroughbred foals are registered with their birthdate as January 1. Horses have long gestation periods, which makes breeding difficult since, in order to have another living foal on the ground at the same time the next year, she must be bred during her first estrous cycle after delivery, which is referred to as a “foal heat,” after she has given birth.

Some mares ovulate as early as 7 to 8 days after giving birth, while others may not ovulation until 14 to 15 days after giving birth.


Early in your mare’s pregnancy, her tummy will appear to be normal in appearance; nevertheless, as the pregnancy progresses, your mare’s stomach will become huge and round. As she gets closer to her due date, her belly expands downward and occasionally flattens out on the sides of her body.

Can you ride a horse that is pregnant?

If a mare is usually healthy and does not have a history of miscarriage, you should be able to ride her until the eighth month of her pregnancy. A frequent myth is that riding pregnant mares is detrimental to their health. More information about riding pregnant horses may be found in the following article: Riding a Pregnant Horse (Mare): What to Do and What Not to Do

Can you transport a pregnant mare?

People who enjoy horses are likely to be really enthusiastic about them, and this is especially true for horse owners who have opted to go with breeding their mare. Breeding horses involves a significant investment of time, money, and patience, regardless of whether the breeder is an individual horse owner with a cherished mare or a large breeding company of any scale. No matter if the purpose of breeding is for profit or for posterity, the process may be both difficult and rewarding. For the horse owner who has committed to breeding their mare and who has done all of the legwork, preparation, and expense of breeding to a stallion or using artificial insemination, the most important question is how to tell if and when their mare has actually conceived.

There is only one “iron-clad, guaranteed” means of determining whether or not a horse is pregnant, and that is through an ultrasound examination of the animal.

1 But there are a variety of additional signals that a horse is pregnant that you should look for.

Transrectal ultrasonography is the most accurate method of determining whether or not you are pregnant.

Consequently, the owner receives the greatest amount of information possible regarding the pregnancy’s state and whether or not any complications are related with the pregnancy. The following are some of the advantages of ultrasound:

  • Early pregnancy diagnosis (as early as day 10 or 11 post-ovulation)
  • Estimation of foaling dates, if breeding dates are unavailable

In mares, the typical gestation duration can be anywhere from 320 and 362 days (about 11 months), with ponies having shorter gestation periods than horses on average. The majority of mares will give birth within 330-345 days following a successful conception; however, even if a mare is an experienced broodmare, it is not always simple to discern if she is pregnant.

In the Days Before Technology

Older horse owners and breeders are likely to be familiar with some of the folk practices (sometimes known as “old wives’ tales”) that were originally employed to determine whether or not a horse was expecting a child. While the most of them are entirely untrustworthy and typically wrong, a handful are worth discussing here, if only to dismiss them from consideration for the fledgling owner/breeder in the first place. A few of the ways for telling if a mare is in foal include placing a threaded needle, ring, or nail connected to a string across the mare’s abdomen, or judging the amount of energy with which the mare shakes her body.

  1. 2 While they may seem ridiculous now, keep in mind that they were sometimes the only information available to horse owners prior to the invention of ultrasonography technology.
  2. In contrast to humans, skipping a heat cycle does not have the same consequences as missing a period (which actually is not a clear indicator of pregnancy in humans either).
  3. When looking at the mare early in pregnancy, it is hard to make a definitive determination or obtain a clear confirmation.
  4. Some mares have a well-sprung barrel and appear to be in foal all of the time, which is not the case.
  5. Some mares may appear to be bloated in the stomach and have milk dripping down their back legs for several weeks before giving birth, while others will not.

So, is She or isn’t She?

Considering that the mare will remain pregnant for nearly a year and may not seem pregnant for several months, it is critical to be alert to additional indicators of pregnancy that may occur. Recognizing these will help the owner or breeder to make the necessary adjustments to the mare’s nutrition, activity, and living conditions as needed.

2 You should keep in mind that some of these procedures are less than scientific in nature, and that confirmation by a veterinarian (ideally one with experience in horse reproduction) is the only reliable way to identify whether or not a mare is in foal.

Mood and Behavior

As previously stated, familiarity with a mare’s regular moods and behavior might provide some clue that a bred mare is in foal, because being pregnant frequently results in a deviation from that baseline. When a mare’s behavior changes significantly, it may be an indication that she is pregnant. Some breeders utilize a change in responsiveness to stallions as a signal, and this is one such indicator. In most cases, mares get cranky or flirty when a male horse comes close by, especially if she is in heat at the time.

Elevated Progesterone Levels

There are a variety of blood tests that an equine reproductive expert may use to identify whether or not a mare has given birth. One of these tests is a progesterone level test, which she will undergo. The majority of mares will have higher progesterone levels throughout their pregnancy, but a baseline level must first be established in order to create a frame of reference for future measurements. The blood test for progesterone, on the other hand, is not always accurate since mares who are not pregnant might occasionally have increased progesterone levels.

Presence of Equine Chorionic Gonadotropin (eCG)

Equine chorionic gonadotropin (eCG) is found in the blood of pregnant mares and is regarded to be a positive sign of the existence of pregnancy. “ECG levels in the blood begin to rise about Day 35 of pregnancy and stay raised until between Day 100 and Day 140 of pregnancy. It is possible to tell if a mare is pregnant or not by using the electrocardiogram (ECG), but only during a small window of time between days 35 and 100 post ovulation. For example, if a mare is around 200 days pregnant, her eCG levels would be zero, and the test would be interpreted as indicating that she is not pregnant.” 3After Day 80 of gestation, a natural rise in total estrogens will occur, 3at which point the mare’s blood may be tested for this rise in estrogens to identify if she is pregnant or if she is still open.

Later in Gestation

It is possible that the mare will become irritable or restless as she goes through the final stages of pregnancy. Changes in the appearance of a mare’s udders are another late indication that she is pregnant. Her udders will begin to fill with milk a few weeks before she gives birth, and this is usually obvious. As she gets closer to giving birth, she may notice other noticeable changes in the look of her udders and teats as well. A transrectal ultrasound of the mare’s uterus will ultimately offer the most reliable early confirmation of pregnancy, the number of days she has been in foal, and whether or not there are any difficulties with the pregnancy at this point in time.

Horse Pregnancy: Signs, Stages, Timeline & Care

Equine pregnancy is just as natural and normal as it is in other animals and humans. However, if this is the first time your mare is expecting a child, we can appreciate your concern and anxiety. The phases of horse pregnancy are split into three categories: Stage 1 is defined as the period between conception and three months after conception. The second stage occurs between 3 and 6 months after conception, when the majority of mares begin to show and the fetus begins to resemble a miniature horse.

Before breeding, you should do a complete medical examination on both the stallion and the mare to ensure that the resulting foal is in good health.

Horses can breed, conceive, and give birth in the wild without the assistance of science, despite the fact that they are not domesticated.

Continue reading for a thorough explanation of horse pregnancy indications, stages, timetable, and care.

Stages of pregnancy in a horse

In the case of horses, the usual gestation duration is 11-12 months. The majority of horses would foal between 330 and 345 days after becoming pregnant. Horses normally reproduce throughout the warmer months. Once the mare becomes pregnant, she will not accept any more approaches from the stallions. For confirmation, you can look for indicators of pregnancy in horses on this website. According to the information provided above, horse pregnancy is divided into three stages:

  • From conception until three months after birth
  • From three to six months
  • And 6 months onwards

These birth stages are classified according to the stage of development of the fetus.

1. Conception to 3 months

An ultrasound performed between 55 and 70 days will reveal a heartbeat, as well as the sac and a little horse baby. The fetus will continue to develop, and by the time it reaches the 3-month mark, it will have taken on the appearance of a miniature horse. A blood test and an ultrasound should be performed as soon as possible after this point. It is common practice to pinch one of the mare’s pregnancies if she is pregnant with twins in order to assure the birth of a healthy foal.

2. 3 to 6 months

The second trimester begins during the third month of pregnancy. During this trimester, the fetus begins to increase in both size and complexity. The sixth month of a horse’s pregnancy is the second major milestone. By the time they reach this month, the majority of mares have begun to show. A mare who has already given birth will show up earlier than a mare who is having her first foal. As the foal develops and acquires weight, the mare’s stomach will continue to expand to accommodate it. This is the time of year when you may wish to avoid riding a mare that is expecting a child.

3. 6 months to Estimated Foaling Date (EFD)

Horses have a gestation period of around 340 days on average. After the sixth month, a mare’s pregnant belly begins to develop rapidly in response to the growth of the unborn foal. A mare’s expected foaling date can be determined using ultrasound technology. The mother’s udder will begin to swell around two weeks before the foal is due, and she may release colostrum, which is a sticky yellow fluid that is thought to be the mother’s first milk and is regarded as such.

That will serve as the first meal for the young horse’s digestive system. Beginning on the 315th day of pregnancy, you should keep a watchful eye on the mare for symptoms of pregnancy. For example, the muscles around the tailhead will begin to relax as the session progresses.

Breeding in horses

In the long summer days, mares would undergo a period of heat after every 21 days of estrous, resulting in a flurry of egg production. Following the initial teasing and courting, the mare and the stallion will engage in sexual activity with each other. The majority of the time, horse breeders will allow both horses to mate until the mare becomes pregnant. Do you require further information? The following is a comprehensive reference on the breeding habits of horses.

Signs of Pregnancy in Horses

Although ultrasound is the most precise method of diagnosing a horse’s pregnancy, there are certain telltale symptoms that might suggest that your mare has already conceived. The following are some of the most typical indications of pregnancy in horses.

1. Refusal to mate

When a mare has already given birth to a foal, she is unlikely to mate. If you allow her to be in close proximity to the horse, she will reject his approaches.

2. No sign of estrus

A mare that has previously given birth will not exhibit any symptoms of being in season.

3. Restricted movements

This one isn’t backed up by any scientific evidence. However, the majority of horse owners believe this to be true. When a mare is pregnant, it is claimed and reported that she would avoid making rapid movements in order to protect the fetus from being injured.

4. Swollen belly

When it comes to horses, the same indicators of pregnancy that apply to people apply. However, the problem with this sign is that it appears as late as 11 months into the pregnancy in the majority of horses. As a result, even if there is a certain indicator, it will not manifest itself until your horse is well into her pregnancy.

5. Rectal examination

A veterinarian is responsible for doing the rectal examination. He would slide his fingers into the rectum in order to feel the uterus, which is a tiny bag that contains the foal and the ovaries, and the ovaries. As early as 15 to 19 days into the pregnancy, this can provide a solid indication of whether or not the mare is pregnant. However, it takes a significant amount of knowledge.

6. Ultrasound

Having an ultrasound performed on a mare is the most accurate means of identifying if she is pregnant. In horses, it is possible to execute the procedure as early as 55 to 70 days into the pregnancy. An ultrasound probe is inserted into the mare’s rectum in order to provide a clear image of the amniotic sac and the uterine cavity. With this test, you may also listen to the foal’s heartbeat for a brief period of time.

7. Blood or urine test

When the pregnancy is between 2 and 3 months along, the blood and urine tests are highly accurate. Do you ever wonder how horses manage to get their views across? A good article on how horses communicate with one another may be found here.

How to Care for a Pregnant Horse?

Horses give birth in the wild in a natural way, without the intervention of a medical facility or any other means of support.

However, on the farms, in order to guarantee that the foal and mare remain in excellent health, you must care for the mare and watch for any warning signals that might indicate a problem during the delivery. Here’s everything you need to know about caring for a pregnant horse.

1. Regular exercise

Mares must maintain a regular exercise schedule and be physically active. Make certain, however, that you do not press them to do considerable tasks. Moderation is essential, and if your pregnant horse doesn’t feel like exercising on any given day, then simply let it alone. More information on whether or not you can ride a pregnant horse may be found here.

2. Proper nutrition

It is preferable to continue feeding the horse her usual diet until the last few months of her pregnancy. As she gets farther along in her pregnancy, gradually increase the amount of grains in her diet and hay. Supplementing with vitamin supplements, salt, and minerals is also a smart move. When it comes to pregnant horses, Farnam Mare PlusGestation and Lactation Supplement is my first choice.

3. Avoid riding the pregnant mare

If you are in the first 6 to 8 months of pregnancy, you are allowed to ride your mare. However, for your own safety, you should refrain from doing so. This has the potential to be harmful to the fetus.


After around 340 days of pregnancy, your horse would be ready to give birth to its foal. The foaling procedure, on the other hand, is not as straightforward as it appears. Foaling necessitates a great deal of planning on your part. Prior to your horse foaling, you’ll need to do a number of tasks, from immunization to preparation of the foaling stall.


A pregnant mare should be vaccinated 6 weeks or a month before foaling, depending on the circumstances. She should be given a booster dose of tetanus toxoid as well as a booster dose of any other diseases that are prevalent in your region.

The foaling stall

If you intend to foal inside, you should prepare the foaling stall prior to the arrival of the calves to the stall. The dimensions of the stall should be 14 by 14 feet. If you don’t have enough room, you may remove the barrier that separates two stalls and turn them into a double stall instead. The floor of the stall should be covered with hay or straw to provide additional comfort for the horse.

Removing the caslick (vulvar stitches)

When purchasing a mare, it is important to have her tested for vulvar sutures. If she has sutures, they should be removed at least 2 weeks before the expected due date of the baby. If you do not remove the caslicks, the mare will suffer a major rip during the process of giving birth. Because the sutures restrict the size of the incision, foaling can cause significant harm to a mare’s perineum throughout the process.

Signs of Foaling in Horses

When the time for foaling approaches, do the following:

  • The udder will enlarge and begin to flow colostrum
  • Nevertheless, A relaxation of the muscles surrounding your mare’s tail head will occur. During pregnancy, her tummy will lower as the foal positions itself for delivery

The Stages of Foaling

The process of foaling is divided into three parts. Stage 1 lasts between 1 and 4 hours, during which time the uterine contractions become stronger in preparation for the delivery. Once the foal is born, it will take anything from 20 minutes to an hour depending on whether or not there are issues during the birth. The transit of the placenta is the third stage of pregnancy in horses, and it may occur as soon as 3 hours after the horse is born.

It is not recommended to interfere with the procedure since it may cause uterine injury to the mare. It is recommended that you visit a veterinarian if the placenta does not pass within 3 hours. A deworming should be performed on the mare within one hour after giving birth.

What to do Right After Horse Birth?

A diluted solution of chlorhexidine or povidone-iodine should be applied to the umbilical cord of the newborn foal many times daily for 2 to 3 days after it is born. The foal should be able to stand one hour after birth and should sip the mother’s milk as soon as possible following the birthing process. Are you unsure about what to feed the foal? Feeding foals is covered in detail in this comprehensive book.

Horse Pregnancy: FAQs

We understand that you have a slew of other questions racing through your head right now. So, in this part, we’ll take a stab at answering some of the most often asked questions concerning pregnancy in horses.

How do I know if my horse is pregnant?

A mare’s pregnancy may be determined via ultrasound, which is the most accurate and reasonably early procedure available. Rectal examination can reveal whether or not a mare is pregnant as early as 19 days into the pregnancy, but it needs a high level of skill and knowledge. Blood or urine tests can also be used to identify whether or not a horse is pregnant, and they can be performed 2 or 3 months after the horse has given birth.

Can a horse have twins?

Yes, horses may produce twins, but it’s extremely unusual. as rare as one in every 10,000 horse pregnancies, according to some estimates. Even if a horse is successful in conceiving twins, one of them is likely to die shortly after delivery. However, there is a success story: Lori Tucker’smare produced two fillies, which was a great achievement. And both of them were healthy and made it through the birthing process.

Can a mare be pregnant and not look pregnant?

Visual examination alone will not reveal whether or not your mare is pregnant. However, although some mares begin to have enlarged bellies about 6 months during their pregnancy, others may not begin to show until the 11th month. There’s also no assurance that you’ll be able to detect any fetal movement in the abdomen of your pregnant mare at the same time. As a result, you should consult with your veterinarian to determine whether your horse is pregnant. Tambako the Jaguar created the featured image.
