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.
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.
When can you tell if your mare is pregnant?
Typical intervals for checking mares are: Day 14 to 16 – confirms initial pregnancy and looks for twins. Day 26 to 30 – confirms heartbeat and fact that fetus is alive. Day 45 – elective examination that has no specific reason since endometrial cups should already be formed by this time.

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.
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 a horse go into heat while pregnant?
Registered. Many mares can and do show signs of being “in season” while pregnant.
How long can a mare carry a dead foal?
What is abortion? Abortion is the delivery of a dead foal and its placenta before an age at which the foal would have been able to survive independently. This is usually taken to be up to day 300-310 of gestation. After 300-310 days, if a dead foal is delivered it is usually termed stillborn.
How long can a mare be pregnant?
The average gestation length of the mare is 340 days (range 315-365 days) and gives ample time to prepare for the arrival of the newborn foal. Mares due in winter tend to carry their foals longer than mares due in summer.
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.
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. Return to the list of recent news
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.
- 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. (TheHorse.com)
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. Uncountable instances have occurred in which an owner had absolutely no notion that their mare was in labor until the baby was born!
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
Equine chorionic gonadotropin (eCG) is found in the blood of pregnant mares, and its presence is regarded a favorable sign 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 very small window of time, from days 35 to 100 post-ovulation. When a mare is around 200 days pregnant, her eCG levels will be zero, and the test will be interpreted as indicating that she is not pregnant.
When the fetus and the placenta are at this stage of development, estrogen is produced, and this may be utilized to determine the viability of the pregnancy.
How Can I Tell if a Mare is Pregnant? – The Horse
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.

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
Mating, the horse gestation time, and foaling are some of the fundamentals of equine reproduction and horse pregnancy. There is only one foal each year that may be produced by a mare (female horse). An adult mare is capable of delivering afoalat at around 18 months old; however, the mare is in better health at least four years old since she will have grown to her maximum size. A mare can have offspring until she is in her late twenties, if she is healthy.
However, even though 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 gestational phase.
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.
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.
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 Check a Mare for Pregnancy
Documentation Download Documentation Download Documentation Mares come into heat in the spring when the days are longer and the sun is shining more brightly. It is estimated that a mare comes into heat roughly every three weeks during the spring and summer. If you have a breeding mare, or whether your mare has gotten into touch with a stallion during her heat cycle, you may wish to find out if she is pregnant before breeding her off. During the 11-month gestation period, or the time a horse is pregnant with a foal, mares do not begin to look about in their stomachs until the last three months of their pregnancies.
- 1Observe the mare’s behavior while she is near stallions. A mare who is suspected of being pregnant might be brought into touch with a stallion fourteen days after first coming into contact with the stallion in order to see whether or not her behavior suggests that she is pregnant. While pregnant, the mare would most likely reject the stallion’s approaches and will not exhibit her rear to the stallion as she would during heat. It is important to be aware that a mare who is not in heat may reject the stallion’s approaches for a variety of different reasons. 2Keep an eye out for indicators of heat in your breeding mare. In addition to becoming generally difficult during their heat cycles, some mares lift their tails, open and close the lips of the vulva, and squat to shoot pee or mucus. It is unlikely that the mare is pregnant if she exhibits these characteristics 21 days after having been presumably impregnated. Advertisement
- s3 Transrectal palpation should be performed by a veterinarian. After a mare has been with a stallion for 16 to 19 days, a veterinarian can conduct a transrectal palpation on her to check for pregnancy. The veterinarian inserts his or her hand inside the mare’s rectum in order to examine the uterus for signs of pregnancy. The size and/or form of her uterus, as well as the type of the swellings on her ovaries, are all indicators that she is pregnant. 4 Have a veterinarian do an ultrasound on the mare to ascertain whether or not she is pregnant. During an ultrasound, the veterinarian must introduce a probe into the mare’s rectum in order to acquire photos that can be used to confirm pregnancy. It is possible to identify pregnancy as early as 16 days, and it may be possible to confirm the gender between 55 and 70 days.
- During an ultrasound, sound waves are used to generate an image of the uterus, which may also be used to monitor the heartbeat of a fetus. Because it is the most reliable means of determining whether or not a mare is pregnant, ultrasound is the method of choice.
- 1 Have a blood test done on your horse to determine her health. A pregnant mare can be tested for pregnancy hormones in order to identify whether or not she is pregnant. A procedure such as this is particularly effective when the mare is too irritable for non-chemical techniques of pregnancy determination or when the rectum is too tiny for physical examination
- Have a veterinarian take a sample of your blood. When the blood sample is collected, the veterinarian will send it to a laboratory to be analyzed. The amount of pregnant mare serum gonadotropin (PMSG) should be tested 40 to 100 days after your mare was in a stallion’s presence.
- PMSG testing may be erroneous if your mare was pregnant but did not give birth to a fetus
- The amount of oestrone sulphate should be determined 100 days after the breeding. A foal is present, and the levels of Oestrone sulphate grow
- However, if the foal is aborted, the levels return to normal.
- 2 Take a urine sample from your breeding mare. When screening mares for pregnancy, the presence of oestrone sulphate in the mare’s urine can be detected. It is possible to have a urine test conducted by a veterinarian or to conduct a home test.
- You may get a home pregnancy testing kit from a feed shop or on the internet. Obtain a urine sample from your breeding mare 110 to 300 days after she has been in contact with a stallion. Using a knife, cut a 1 gallon (3.8 L) or a 2-liter liquid bottle in half lengthwise. Use the bottom to catch the pee from your mare. In order to examine your mare’s pee, follow the instructions on the pregnancy test kit. Obtaining the findings takes about ten minutes.
- 3Confirm the findings of the pregnancy test. However, it is recommended that you have another test conducted by a veterinarian, whether chemical or non-chemical, to check that the foal hasn’t slipped the foetus and that your mare is indeed pregnant. Additionally, because chemical-based tests are occasionally performed incorrectly, a positive result should be validated by a veterinarian. Advertisement

- In order to identify whether or not a pregnant mare is carrying twins, horse owners frequently choose to have a veterinarian administer the initial pregnancy test. Having twins can be hazardous to your horse’s health
- Breeding mares are prone to slipping, or miscarrying, their foals within the first 100 days of their pregnancy. A home pregnancy kit is a low-cost means of performing a second pregnancy test after the original 100-day period.

About This Article
Summarized from the articleXTo check a mare for pregnancy, begin by keeping an eye on her among stallions 14 days after you suspect she has been impregnated. If she rejects their approaches, it is possible that she is pregnant. After 21 days, keep an eye out for indicators that she’s in heat, which indicates that she isn’t expecting a child. Behaviors such as lifting her tail, expanding and shutting the lips of her vulva, and crouching to spray pee, for example, are all signals that she is about to come into heat.

The following is an overview of how to check a mare for pregnancy. To begin, observe her with stallions 14 days after you suspect she has been pregnant. The possibility of her being pregnant is raised if she rejects their approaches. Examine her for evidence that she is in heat after 21 days. If she isn’t, she isn’t pregnant. Behaviors such as lifting her tail, expanding and shutting the lips of her vulva, and crouching to spray pee are all typical indicators of a female cat in heat. To be sure, have your veterinarian do an ultrasound, which is the most accurate way to determine whether or not a mare is pregnant, to confirm your findings.

Non-chemical methods
Changes in behavior: The mare’s attitude toward a stallion might be a strong predictor of her readiness to breed. A pregnant horse should begin to refuse a stallion’s approaches around 14 days after completing her sentence. To put it another way, they will not exhibit the typical behavior, which includes accepting his approaches and “showing” their behind. In the case of a mare who does not begin her oestrus cycle within 21 days following being served, it is reasonable to infer she is pregnant.
Veterinary transrectal palpation is when a veterinarian inserts his or her palm into the rectum and palpates the uterus for symptoms of pregnancy.
Despite the fact that this approach may be employed as early as 16 to 19 days into pregnancy, it requires a significant amount of competence on the part of the veterinarian.
It is also capable of detecting the heartbeat of the foetus. Ultrasound may be used to diagnose pregnancy as early as day 16, and it can even tell the gender of the baby as early as day 55 to 70. A highly trained operator is required for ultrasonography, and the equipment itself is costly.
Chemical methods
Changes in behavior: A mare’s attitude toward a stallion might be an excellent predictor of her readiness to breed. A pregnant mare should refuse the overtures of a stallion starting roughly 14 days after serving. To put it another way, they will not exhibit the typical behavior, which includes accepting his advances and “showing” their behind. It is reasonable to infer that a mare is pregnant if she does not begin her oestrus cycle within 21 days following being served. The behavior of their mare(s) may also vary slightly when she begins to “bloom” in pregnancy, which experienced breeders may detect as well.
It is important to note that there are several factors that influence pregnancy, including uterine tone, uterine shape, and the presence and size of the amniotic vesicle (a tiny sac that contains the foetus).
It is possible to do an ultrasound on a mare by inserting a probe into the rectum of the mare and using sound waves to create an image of her uterus, her foetus, and her placenta.
On average, ultrasound can identify pregnancy from approximately day 16 on and can even determine the gender between 55 and 70 days after conception.
Urine-based pregnancy testing
The oestrone sulphate generated by the foetal-placental unit not only enters the maternal system, but it also passes through the mare’s urine. It has been accessible for some time that breeders may test for oestrone sulphate in urine, but doing so has required that the breeder send the collected sample to a laboratory for analysis. Wee-Foal-Checker is a mare-side version of the laboratory urine test created by Dr Henderson and his research partner, Kim Wearne, recently published in the journal Science.
It needs less than 1 milliliter of urine and can be used from 110 to 300 days after the breeding cycle has concluded.
In many cases, the expense of pregnancy testing a mare, particularly a confirmation test later in pregnancy after an early pregnancy test, is enough to deter owners from doing so.
Important considerations
There are two choices available to horse owners: having a veterinarian test their mare’s pregnancy or conducting their own pregnancy tests. If owners choose to conduct their own testing, they can choose between blood and urine tests. Owners who conduct home tests must make certain that they understand the nature of the test and that they only use the test within the timeframe specified by the test’s manufacturers before proceeding. If you do not follow these instructions, you run the risk of getting an inaccurate result.
- Others will choose to have their mare examined by a veterinarian as soon as possible to rule out the potential that she is carrying twins.
- When used properly, they give horse owners with an opportunity not only to save money, but also to demonstrate that their mare’s slowly rounded belly is due to a foal – rather than the spring grass – with a later second test.
- How to collect urine in a proper manner For horse owners, the main challenge that arises from a home-based urine test is how to obtain a sample of pee.
- Keith Henderson argues that some breeders have an easy time, while others struggle to make a living.
- It is not necessary to collect the entire amount of urine excreted.
- In addition, Gill Booth of KeriKeri has developed a simple gadget that may be used to collect data.
- Mares, according to him, are only vaguely aware of its presence.
The ideal collecting bottle, according to research, is a 2-litre juice container that has been sliced in half. Incorporating a small amount of cotton wool inside the container guarantees that a small amount of pee will be preserved even if a leak occurs before you have a chance to collect it.
Pregnancy testing miniature horses
Pregnancy testing miniature horses is impracticable due to their small size. Traditional procedures used for full-size mares, such as manual palpation via the rectum or ultrasound technology utilizing a rectal probe, are ineffective due to the small size of miniature horses. The measurement of chemical hormones linked with pregnancy, which are present in the blood and/or urine of pregnant mares, provides an alternative and reliable method of testing miniature horses for pregnancy and tracking the progress of pregnancy during the gestational period.
Taking blood PMSG concentrations between 40 and 100 days after mating is advised for detecting pregnancy status between these two time frames.
The existence of a living foetus is indicated by elevated levels of the hormone oestrone sulphate.

Equine Pregnancy
According to the American Association of Equine Practitioners, an average equine pregnancy lasts between 338 and 343 days from the time of conception to the time of delivery. According to the American Association of Horse Practitioners, the average duration of an equine pregnancy is between 320 and 380 days. It is possible that your mare will be pregnant for more than a year after she was first introduced to the stallion due to the extended gestation period. If you have any reason to believe your mare may be pregnant, contact your veterinarian to confirm the pregnancy.
Physical Appearance
According to the American Association of Equine Practitioners, an average equine pregnancy lasts between 338 and 343 days from the time of conception to the time of birth. Pregnancies in horses are typically between 320 and 380 days long, according to the American Association of Equine Practitioners. Your mare might be pregnant for more than a year after she was first introduced to the stallion because of the extended gestation period. If you have reason to believe your mare is pregnant, contact your veterinarian to confirm the pregnancy.
Udder
It is possible to tell whether or not your mare is pregnant by looking at her udder. You will notice that your mare’s udder is beginning to fill with milk two to four weeks before she gives birth to her offspring. You should notice that your mare’s teats are distensing and beginning to have a waxy look when she is less than a week away from giving birth. It is also possible for a mare who is extremely near to foaling to spill milk from her teats. All of these indications of pregnancy are also indicators that your mare is on the verge of giving birth.
Veterinarian
Your veterinarian can establish whether or not your mare is pregnant by physically palpating her or by using an ultrasound machine to examine her. These tests will also inform you how far along your mare’s pregnancy is in the process of being performed. A veterinarian will also be able to sex the unborn foal, as well as identify and treat any problems your mare may be experiencing during pregnancy.

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?
In order to tempt stallions to mate with them, mares that are not pregnant and in heat will naturally raise their tails to attract attention. While they might be irritated in the days leading up to their heats, a mare who is not pregnant will welcome a stallion who approaches her and seeks to ride her. Pregnant mares will frequently refuse to be mounted by a stallion because they are pregnant. If the mare in question consistently rejects the overtures of a stallion, this might be another indication that she is pregnant.

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 observe movement in your horse’s abdomen, it might be a sign that there is a baby rolling about inside of him. When a mare is nearing the conclusion of her pregnancy, you will be able to see rapid movement in her belly as the foal begins to outgrow the space available to it. You may even notice that your horse’s excessively huge 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.
If you observe movement in your horse’s abdomen, it might be a sign that there is a baby rolling about inside of it. When a mare is nearing the conclusion of her pregnancy, you will notice rapid movement in her tummy as the foal begins to outgrow the available space. In certain cases, you may even see that your horse’s unnaturally huge belly has become flat on the sides and almost points downwards, indicating that something has changed. On the surface, it will appear that the foal has migrated closer to the birth canal.
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
Consider your mare’s current state of mind and whether her disposition has shifted. In the latter stages of pregnancy, a pregnant mare may become more irritable than she is used to being during her pregnancy. She may be less sociable with other horses, and you may notice her distancing herself from the rest of the herd when this happens. It is common for a pregnant horse to pace and appear restless. When horses are merely overweight and not pregnant, they shouldn’t exhibit any significant changes in their usual attitude or temperament.
Due to the fact that a female’s attitude can also alter during her heat cycles, mood changes are never a certain predictor of pregnancy.
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.

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 |
