How To Tell If A Horse Is Pregnant? (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.

How long does it take for a horse to show signs of 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 I tell if my mare is pregnant or fat?

One of the first signs is the distended udder. During the last month, the udder usually enlarges. The mare’s udder may fill up at night while she is resting and shrink during the day while she exercises. When the udder remains full throughout the day then foaling is probably imminent.

Can you use a home pregnancy test on a horse?

The Wee-Foal-Checker test kit. A revolutionary $30 do-it-yourself pregnancy test for mares delivers a result within 10 minutes, its New Zealand developers say.

Can a horse sense pregnancy?

Just like humans, horses can get ultrasounds to detect pregnancy. Once inserted into the rectum, the probe will send sound waves to detect a heartbeat, uterus, and placenta.

How do you know when 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.

Can a pregnant mare show signs of heat?

Some mares will appear to have a heat cycle despite being in foal. Some mares may not show an obvious heat cycle, especially through the fall and winter months. Pregnancy is impossible to determine early on simply by looking at the mare.

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 preg check a horse?

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.

Will a pregnant mare accept a stallion?

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

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.

Can riding a horse cause miscarriage?

“You never know what’s going to happen when there’s a horse in the picture. If you get hurt or if you get kicked, it can affect the baby. However, you can’t make yourself miscarry from riding and you can’t make yourself go into labor from riding. The biggest concern would be trauma to the abdomen.”

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.

In addition to a lack of interest in stallions, your horse may demonstrate additional behavioral changes during the early stages of pregnancy. 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!

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.

If she is hesitant to join in an activity, it is preferable to follow her instincts and not force her to do so. 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.

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 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.

  1. If the yellowish fluid is allowed to ferment, it will transform into the first milk or colostrum.
  2. It is possible that her stomach will appear to lower as the foal aligns itself for delivery.
  3. The mare will look restless shortly before giving birth, and she may paw the ground and examine her flanks (similar tocolic symptoms).
  4. The mare may lie down and rise up several times, but she will give birth while lying down on the ground.
  5. At this point, the foal is usually born within a few minutes of being born.
  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.

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

If you’re wondering whether or not your mare is pregnant, there are a few things you may do to find out. In the case of a female horse, the gestation period is around eleven months. For the first several months, it will be difficult to tell whether or not a mare is carrying a foal. For the sake of both the mare’s personal health and the health of the foal, it is critical that she get good care from the beginning of her pregnancy until the end of her pregnancy.

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.

How to Tell if a Horse is Pregnant

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
  • And visualization of the fetus and its heart beat at 25 days or more in foal are some of the procedures that are available. (

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.

  • 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.
  • 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).
  • When looking at the mare early in pregnancy, it is hard to make a definitive determination or obtain a clear confirmation.
  • Some mares have a well-sprung barrel and appear to be in foal all of the time, which is not the case.
  • 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.

How To Tell If My Horse Is Pregnant: Signs, and What to Do

Any links on this page that direct you to things on Amazon are affiliate links, which means that if you make a purchase, I will receive a compensation. Thank you in advance for your assistance — I much appreciate it! Your mare has been introduced to a stallion, and she is no longer performing in the manner that she used to. As a result, you begin to worry if she is pregnant, but how can you tell for certain? Are there any symptoms that your horse is pregnant that you may look for? Behavior and hunger changes, weight increase, missing estrus cycles, and swollen udders are all signs that a mare is pregnant.

The behavioral and physical changes that occur during each period of horse pregnancy are distinct from the others.

However, if you want to be certain that your horse is pregnant, there are many more indicators to check for than these.

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.

It is essential for horse breeders to breed their mares as soon as possible after foaling because Thoroughbred foals are registered with their birthday on January 1st, which makes breeding difficult. Because of the long gestation periods of horses, it is necessary to breed a mare as soon as possible after foaling because to have another live foal on the ground is to have another live foal on the ground is to have another live foal on the ground.


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?

I received the following question through email: Q.How can I know whether my mare is pregnant? A. Veterinarians can use a variety of procedures and tests to identify whether or not a mare is pregnant, depending on the situation. In order to determine whether or not a mare is in foal, it is necessary to look at her usual physiological processes that occur during the pregnancy. All techniques of pregnancy diagnosis have certain limits, and they all have the potential to provide false positive or false negative findings in some instances.

The majority of non-pregnant mares display indications of estrus in a regular rhythm, indicating that they are about to become pregnant.

Experts believe that 5-10 percent of pregnant mares still display estruslike indications when approached by a stallion, despite the fact that they have failed to return to estrus after a period of time.

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:

  1. Detection of pregnancy at an early stage (as early as day 10 or 11 post-ovulation)
  2. If the breeding dates are uncertain, an estimate of the foaling dates can be made. and
  3. Visualization of the fetus and its heartbeat during 25 days or more in the foal’s pregnancy
  4. And

There are a number different blood tests that you can use to establish whether or not your mare is open or pregnant, with some providing better findings than others. Following the detection of pregnancy by the mother at roughly Day 12-14 post-ovulation, progesterone levels in pregnant mares should stay increased throughout the duration of the pregnancy. However, not all mares with high progesterone levels upon maternal identification will be pregnant at the time of testing. Because high progesterone levels are seen in both pregnant and non-pregnant mares, assessing progesterone concentrations in the blood has little diagnostic potential for determining pregnancy.

  1. The presence of equine chorionic gonadotropin (eCG) in a mare’s blood is a straightforward positive sign of pregnancy in this animal.
  2. However, only during a very small window of time, from days 35 to 100 after ovulation, is the electrocardiogram (ECG) a valid method of diagnosing whether your mare is pregnant or not.
  3. After the 80th day of pregnancy, a natural increase in conjugated estrogens or total estrogens occurs.
  4. Estrogen is generated by both the fetus and the placenta and may be utilized to determine the viability of a pregnancy in the womb.
  5. If your mare is pregnant, a transrectal ultrasound of her uterus will provide you with the most accurate information on how many days she is in foal and whether or not there are any difficulties with the pregnancy at the earliest possible stage.
  6. If you know when your mare was bred, you may choose the proper eCG or total estrogens tests to establish whether or not she is pregnant and whether or not the pregnancy is viable.

Signs A Horse Might Be Pregnant

Who doesn’t adore a good foal? However, bringing babies into this world and dealing with pregnant mares may be a pain, no matter how adorable they are. The question is, how can you detect whether or not a horse is pregnant? Throughout a mare’s pregnancy, she might be twice as irritable as a person during the first 2-3 months of her pregnancy. Having the ability to forecast when horses will breed, recognize the indications of a pregnant mare and know what to do with your mare if you discover that she is pregnant is essential when working with breeding horses, as well as when working with any other animals.

Are you dealing with pregnant mares for the first time, or are you just interested about how the procedure works? Proceed with caution, and be aware that the procedure will not be as as adorable as the finished product!

When Do Horses Breed?

Horses, like many other animals, are more likely to reproduce at certain periods of the year than at others. A mare’s gestation cycle can last anywhere from 11 to 12 months, and she will bear her babies for over a year!

How Long Is A Horse Pregnant?

As a human being, that’s around 2-3 months longer than the normal gestation time, or practically another trimester! Mares that have already given birth will occasionally be able to carry their foal for a shorter amount of time than mares who are carrying their first foal. However, like with everything, the outcome will be determined by the horse. It is in the nature of horses to desire their foals to be born in warm, springtime weather so that they would be warm and have access to lush green forage.

Horse breeders, on the other hand, have worked out how to manage this natural process in order to have foals at the times of year that suit them most.

When Can You Tell if a Horse is Pregnant?

When it comes to horses, just like it is with people and other animals, you may not know if your mare is pregnant or not for some time after she has conceived. The fact that she will not go into heat during the first three months may be the most significant indicator. It’s possible that you won’t know until after the first three months of her pregnancy or until after her pregnancy has ended. Your mare will not begin to “show” (i.e., become noticeably pregnant around her barrel) until she is around six months pregnant, depending on her breed.

How To Tell If A Horse Is Pregnant?

There are a variety of techniques to determine whether or not your mare is pregnant. Some of them are just old wives’ tales, while others have scientific merit. Transrectal ultrasonography is one of the most accurate scientific ways of determining whether or not your mare is pregnant.| When your mare is ten or eleven days post-ovulation, transrectal ultrasonography can identify her pregnancy, indicating that she is extremely early in her pregnancy. If you’re not sure when the breeding took place, it can also offer you an approximation of when the foaling took place.

Blood Tests

Blood tests may also be used to determine whether or not your mare is pregnant, just like they are for people. If your mare is pregnant, she will have higher levels of progesterone in her blood, which indicates that she is pregnant. However, this test is not infallible, as high progesterone levels have been seen in mares that are not pregnant in rare instances.

Blood tests that reveal the presence of equine chorionic gonadotropin (eCG) are, on the other hand, a straightforward positive sign of a mare’s pregnancy. In most cases, however, this will not be evident until a few days after the first month of a mare’s pregnancy.

Behavioral Signs

Your mare will frequently display behavioral signals that she is pregnant, even at an early stage, despite the fact that they are less definite than scientific testing. Disinterest in geldings or stallions is by far the most common of these. Mares have traditionally been known to become grumpy or “flirty” when around male horses. The likelihood of your mare being pregnant is high if she is not displaying the same emotional responses to male horses as she normally does. Also according to legend, when a mare is pregnant, she will simply shake her head and neck, rather than shaking her entire body in order to protect her unborn foal.

What Should You Do if a Mare is Pregnant?

It is critical to have frequent checks for your mare and her foal while she is pregnant, as well as to adhere to any advice your veterinarian may give you during this time. Your horse’s nutrition will need to be altered from time to time, and their turnout will also need to be adjusted from time to time. Depending on the conditions of each particular horse, different things will be able to be done to assist them. However, maintaining frequent contact with a veterinarian who is familiar with foaling mares will assist you in determining the best way to care for your pregnant mare.

And, as is always the case, contact your veterinarian promptly.


Having a pregnant mare may be a difficult and exhausting experience, but the end product will be well worthwhile! Make sure you can identify your mare’s pregnancy early on so that you can get her assessed by a veterinarian as soon as possible and know how to keep her as comfortable as possible during the pregnancy. Both scientific and natural methods may be used to determine whether or not your mare is pregnant; whichever method you use, make sure to exercise caution and keep your horse’s best interests in mind at all times.

I hope this post has helped you understand how to identify if your horse is pregnant and what you should do if your horse is pregnant.

Observing your horses develop and give birth to a foal is a unique and unforgettable event. Unfortunately, there are situations when what we believe to be a baby horse growing in a horse’s tummy turns out to be merely fat, or vice versa!

The majority of the time, merely glancing at a female horse, often known as a mare, will not reveal whether or not she is pregnant. Here are 13 techniques to determine if a horse is pregnant or simply overweight.

1.Has Your Mare Been with a Stallion Recently?

During the previous 13 months, the mare in issue must have been in the company of an intact male horse stallion, in order for her to be considered pregnant. The majority of mares carry their offspring for anywhere between 320 and 370 days, with some carrying them for even longer. This means that a horse may be able to go somewhat longer than 12 months without giving birth in rare instances. If you are certain that the mare has not been with a stallion during this time period, then there is a larger probability that she is simply overweight and does not need to be gelded.

2.Is the Horse Skipping Her Regular Heats?

Mares should be subjected to a heat and a cycle on a regular basis throughout the year. This occurs often throughout the summer months, about every 18 to 23 days. An expectant mare will not display the typical indicators of being in heat, such as shrieking, pacing, or lifting her tail, among others. Unpregnant mares should cycle in and out of heat every few weeks or so from April to the end of September, assuming they are not pregnant. Pay great attention to the mare that is being discussed. If she is still suffering regular heat cycles, it is most likely due to her excessive weight.


3.Does the Mare Refuse to Stand for a Stallion?

Several times a year, mares should be exposed to heat and cycle. During the hotter months, this occurs often, approximately every 18 to 23 days, depending on the temperature. An expectant mare will not exhibit the typical indicators of being in heat, such as shrieking, pacing, or lifting her tail, among others. Unpregnant mares should cycle in and out of heat every few weeks or so starting in April and continuing until approximately September. Observe the mare with care. She may be pregnant. It’s likely that she’s merely overweight if she’s still having regular heat episodes.


4.She Has Gained Weight for No Other Reason.

Whenever their calorie intake is increased or when they are less active than normal, the majority of horses gain weight on their own accord. Is there anything you’ve done differently recently, either in terms of activities or food? Horses who are active and are abruptly halted but continue to be fed the same amount typically gain weight. Despite the fact that nothing has changed, a pregnant horse will gain weight. If the mare’s activity level has not reduced, and you have not made any changes to her nutrition recently, it is possible that she is pregnant and the weight increase is the result of this.

5.Her Belly is the Only Thing Growing.

Weight gain will occur throughout the body of a horse that is just overweight or obese in the first place. Fat will accumulate in places that were previously well-delineated. Their necks, chests, and bellies, as well as their hindquarters, will all grow in size but retain little definition as a result of this. The majority of a pregnant mare’s weight growth will occur in her stomach. Her other bodily parts, with the exception of her udders, are expected to remain essentially the same size as they were before she became pregnant.

As an example, consider whether she would appear to be overweight if you could not see her stomach. If the response is no, it is possible that she is pregnant.

6.There is Movement in Her Abdomen.

If you notice movement in your horse’s abdomen, it could be a sign that there is a baby rolling around inside of him. When a mare is nearing the end of her pregnancy, you will be able to notice sudden movement in her belly as the foal begins to outgrow the space available to it. You may even notice that your horse’s abnormally large belly has become flat on the sides and almost points downwards, indicating that something has changed. On the surface, it will appear as though the foal is moving closer to the birth canal.

7.Her Udders Are Getting Bigger.

A mare’s udder will begin to develop around two weeks to a month before she gives birth as it fills up with milk and prepares to give birth. The udders may even begin to leak milk a few days before she gives birth to her foal. Whether you have a pregnant mare and an unpregnant mare, you may compare their udders to determine if they are different in appearance. If your mare’s udders have not enlarged as expected, this does not always imply that she is not expecting a foal. A plump and swollen udder, on the other hand, is a clear indication of pregnancy, as well as a sign of imminent labor and birth.

8.How is Her Mood?

Consider your horse and whether or if her disposition has altered recently. When a pregnant horse is reaching the conclusion of her pregnancy, she may become more agitated than she is accustomed to. There is a possibility that she will be less sociable with other horses, and you may discover that she has separated herself from the group. A pregnant horse may frequently pace and appear restless, as well as pacing and seeming restless. When horses are merely overweight and not pregnant, they shouldn’t exhibit any significant changes in their normal attitude or temperament.

Mood swings are never a sure sign of pregnancy because a woman’s attitude might vary during her menstrual cycle as well as during pregnancy.

9.Check Her Vulva

In the weeks leading up to delivery, a mare’s vulva, or lady parts, will begin to relax and become more loose. It involves preparing the body for the stretching that will occur during childbirth and delivery. During your horse’s prospective pregnancy, it is possible to see changes in the vulva about day 315 of the horse’s life. (source) Identifying whether or not your horse is pregnant can be done by comparing her vulva to that of an unpregnant horse. A fast search on Google will yield several images that you may use as a starting point.

10.Test Her Urine with an At-home Equine Pregnancy Test

Invest in your own at-home horse-specific pregnancy test and do your own tests! If you are unsure whether or not your horse is pregnant, an at-home test may be the most convenient and cost-effective alternative before calling in a specialist. Over-the-counter equine pregnancy tests are sensitive to the presence of estrone sulphate, a hormone that indicates the presence of pregnancy in horses.

Consider the possibility of a false negative for some tests, and that the test should not be conducted before 110 days from the day you believe she may have been impregnated. (source)

11.Get a Vet to Test Her Blood.

Your horse’s blood can be drawn by your veterinarian to determine whether or not pregnancy hormones are present in the animal. It is possible to perform a blood test to identify pregnancy hormones in a horse that you suspect is pregnant. A blood test is far less expensive than the more intrusive inspections and testing that your veterinarian can conduct. This test is most effective by day 70, when the hormone levels are high enough to be detected in the vast majority of horses tested. (source)

12.A Vet Can Perform a Rectal Palpitation.

Rectal examination by your veterinarian can determine whether or not there is a developing foal or a swollen uterus. Inaccurate rectal palpation can be detected as early as day 30 of pregnancy, however accuracy is dependent mostly on the practitioner’s expertise and ability. (source) While rectal palpation is generally regarded to be low-risk, there is always the possibility of problems. During farm visits, it is one of the most often conducted pregnancy checks by veterinarians. Consequently, it is critical to only allow qualified professionals to do the palpation since a rectal rupture might develop if an unskilled examiner performs it.

13.Confirmation Via Ultrasound.

The most efficient and cost-effective method of confirming a suspected pregnancy with an ultrasound is to have a veterinarian do the procedure. If you want to know for certain if your horse is pregnant or simply overweight, an ultrasound is by far the most effective method. Another alternative is to invest in a portable ultrasound scanner that you may use at your convenience in your house. It is the more expensive choice up front, but it may be used numerous times for multiple horses over the course of several years.

Always keep in mind that, as we previously stated, horses can rip during a rectal ultrasound examination.

Ultrasounds should only be performed by trained specialists.

  • Genmine Ultrasound Scanner with Sector Probe
  • Portable Livestock Ultrasound Scanner with Rectal Probe

Horse Pregnancy Test Options

There are several of the ways listed above that are not definite and might have alternative explanations that do not include pregnancy. Hormones and ovarian cysts, for example, might lead a mare to exhibit symptoms of pregnancy without her knowledge. Horses can be tested for pregnancy using a variety of different methods. Here are some of the most frequent, as well as an estimate of their costs: Remember that having your mare evaluated by a certified veterinarian is the most accurate way to establish whether or not she is pregnant.

Method Vet Required (Y/N) Estimated Cost Accuracy
At-Home Urine Test No $37 to $60 Fair
Blood Test Yes $25* Fair
Portable Rectal Ultrasound No $0-$850** Good
Portable Ultrasound No $0-$980** Good
Rectal Palpitation Yes $50 Very
Vet Ultrasound Yes $55 Very
