Broodmare

A mare lowering its neck to the ground.

Waiting upward of 11 months to finally meet the foal you've been dreaming of can be filled with excitement, nerves and even quite a few questions. We're here to help guide you through what to expect at each stage.

Pregnancy stages

Pre-Breeding and First Trimester

(0-3 months)

Provide mares with routine wellness care these first 30-90 days to help minimize stress and potential complications/illness.

Horse nuzzling a foal lying on straw in a stable.
Broodmare care tips

Schedule pregnancy checks

Confirm the progress of your mare’s pregnancy via regular ultrasounds and health exams led by your veterinarian.

Keep an eye on stress 

According to the American Association of Equine Practitioners (AAEP), stress has the potential to cause a drop in progesterone, a hormone that helps maintain pregnancy.1 Avoid unnecessary travel and excessive stress and monitor your mare’s vital signs.

Continue with routine wellness

Keep up with regular farrier and dental visits throughout pregnancy to help your mare feel her best.

Dewormers

Deworming in the first trimester

Before breeding your mare, be sure she’s up to date with your veterinarian’s recommended deworming schedule. 

  • Ask your veterinarian to perform a fecal egg count (FEC) test to learn if she’s a high shedder, especially if she traveled off-property for breeding—there may be an increased risk of parasitic exposure on other farms
  • FEC tests determine if your mare needs additional deworming before exposing her to new pastures or other horses

View our deworming guide

Vaccines

Ensure vaccinations are up to date

Check your mare’s vaccination history before breeding to help protect against all five core equine diseases—Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE), West Nile virus (WNV), tetanus and rabies. 

  • Remember to ask your veterinarian about potential risk-based diseases of concern in your geographic area, including equine influenza, equine herpesvirus and other risk-based diseases.  

View our broodmare vaccine guide

Second Trimester

(4-7 months)

Stay attuned to balancing nutrition and physical activity to help support your mare’s vitality.

Broodmare care tips

Evaluate nutritional needs

The AAEP recommends a diet that includes high-quality forage, hay and clean water.1 Monitor body condition to make informed decisions when adding to or modifying your mare’s nutritional plan.

Movement matters

Maintain regular exercise routines in the first 7 months of pregnancy, since it can positively impact the overall health of both mare and foal.

Dewormers

Deworm in the late grazing season

The second trimester typically overlaps with the late grazing season, spanning October to December depending on your location. 

  • Deworm your pregnant mare to help control small strongyles (including encysted forms) and tapeworms.

View our deworming guide

Vaccines

Vaccinate to reduce the risk of abortion

Your veterinarian will likely administer the first of 3 vaccine doses in this trimester to help protect mares against abortion due to infection caused by equine herpesvirus type 1 (rhinopneumonitis).

  • The AAEP recommends this vaccine as early as 5 months into pregnancy (the second trimester) and again at 7 and 9 months (the third trimester).14 
  • Consider vaccinating against leptospirosis: Ask your veterinarian if your mare should be vaccinated against equine leptospirosis—a costly disease that can cause abortions in pregnant mares

View our broodmare vaccine guide

Third Trimester

(8-11 months)

Revisit recommendations designed to help provide your mare with increased nutritional support and preventive care as she enters her third trimester.

Broodmare care tips

Seek nutritional guidance

Your mare’s nutritional needs increase by about 30% while her developing foal grows in the final trimester. Consult your veterinarian for a tailored nutritional plan to support essential vitamin and mineral requirements.

Continue with light to moderate exercise

It's important to avoid strenuous exercise. According to the AAEP, a pastured mare can receive the full amount of movement needed simply from grazing.1 

Dewormers

Deworm in the spring (early grazing season)

The third trimester typically overlaps with the early grazing season, which spans March to May depending on your location. 

  • Deworm your mare to protect against small strongyles, including the encysted stage. Learn more in this blog.

View our deworming guide

Vaccines

Schedule pre-foaling vaccines

Your mare passes immunity to her foal through the colostrum (the first milk rich in maternal antibodies). It’s important to make sure your mare is properly vaccinated for diseases that could affect her foal during the last 4 to 6 weeks of pregnancy—it may also have the effect of boosting antibodies in the colostrum to protect foals against disease when they arrive. 

  • The AAEP recommends mares receive a booster to help prevent all core-based equine disease antigens (EEE, WEE, WNV, tetanus and rabies) along with veterinarian-recommended vaccinations for risk-based diseases.14
  • At 8 months’ gestation, if appropriate based on risk, your mare may receive her first dose of vaccine to provide passive transfer of antibodies to foals against equine rotavirus. A second dose is given a month later at 9 months’ gestation, and a third dose is given at 10 months’ gestation. 
  • At 9 months, your mare may receive her third dose of vaccine that helps protect against abortion due to equine herpesvirus type 1 (EHV-1) infections

View our broodmare vaccine guide

Foaling Window

(pre-foaling, foaling and post-foaling)

It’s time to prepare for immediate pre-foaling care and postpartum wellness checks to help set mare and foal up for success.

Pre-foaling

Prepare for arrival

Organize your barn and monitoring equipment while stocking up on supplies. It’s helpful to create a delivery “go bag” and foaling kit in advance (read this blog for more information).

Monitor for infection

Call your veterinarian to screen mares for possible infection with serum amyloid A (SAA) testing if you notice premature udder development, vulvar discharge or a fever greater than 101.5 F.

Be on the lookout for signs of foaling

2 to 6 weeks prior to your mare’s due date, you should start noticing gradual udder development. As delivery approaches, the mare's teats will wax and her mammary secretions will change from clear and watery to opaque.

Foaling

Learn the stages of labor

Prepare for the stages of labor and arrange the right foaling space in advance. 

Be a present, quiet observer

Your mare needs a quiet, safe space for foaling. Most labor is uncomplicated and goes smoothly—learn about potential flags to watch for in this blog.

Post-foaling

Schedule a post-foaling exam

Your veterinarian should complete an exam on both the mare and foal 12 to 24 hours post-foaling. Be sure to save the placenta in a plastic bag or covered bucket (to keep it moist) for your veterinarian to examine at the appointment.

Bloodwork needed for foals

In addition, your veterinarian will complete a physical exam on the foal, they may also perform bloodwork to ensure passive transfer of antibodies (an IgG test) along with a test for infection in the blood by evaluating SAA data, a CBC (complete blood count) or chemistry panel to evaluate organ functions (e.g., liver and kidneys). 

Perform a nursing exam

Your veterinarian will also perform a complete physical exam on your mare, paying attention to her udder to ensure she’s producing milk and her foal is nursing. They will also evaluate the placenta as part of a newborn foal exam to ensure it has passed in its entirety and there are no signs of infection. 

Observe mares and foals for the first 24 hours

Keep a close eye on mare and foal after foaling to ensure they’re alert and breathing normally. 

Know the 1-2-3 rule

Foals should stand within 1 hour of delivery and nurse within 2 hours, and the placenta should pass within 3 hours. Call your veterinarian if you have any cause for concern.

Ensure foals get adequate colostrum

Visit the AAEP site for more information to confirm that foals are receiving the right amount of colostrum to support their health.15 It’s important that you observe the foal nursing within the first hours of birth and regularly thereafter (several times an hour). If you notice the mare is dripping milk, this is a sign that the foal may not be nursing and is a reason to call your veterinarian.

Deworming

Deworming is essential to help keep your broodmare unburdened by parasites while she's busy supporting her developing foal.  Focus treatment during gestation to address the most threatening parasites to her health and her environment (small strongyles and tapeworms).  Ask your veterinarian to perform a fecal egg count (FEC) test to determine if she is a high shedder or if she needs a treatment effective against roundworms prior to foaling.

Quest® Gel (moxidectin) and Quest® Plus Gel (moxidectin/praziquantel) have been evaluated as safe for use in breeding and pregnant mares and are the only equine dewormers that target the most threatening parasites, including encysted small strongyle larvae, in a single dose. Quest Plus Gel also includes a second active ingredient, praziquantel, which provides an expert-recommended late grazing season (fall) treatment against tapeworms, which also present serious health threats to horses.

You should start to notice gradual udder development. As delivery approaches, the mare’s teats will wax and her mammary secretions will change from clear and watery to opaque.

Foaling and the first few weeks

Know the 1-2-3 rule

One of the most important milestones for a foal is to stand within 1 hour and nurse within 2 hours of foaling, and mares should pass the placenta within 3 hours of foaling. Contact your veterinarian immediately if any of these milestones do not occur on the 1-2-3 timeline.

Monitor vitals

Observe foals for signs of illness like lethargy, decreased nursing, increased breathing rate and effort, elevated body temperature and diarrhea. 

Schedule a newborn foal exam

Ask your veterinarian to conduct a physical exam of both mom and baby in the first 12 to 24 hours after arrival, including an evaluation of the placenta.

Get on your farrier’s calendar

Foals should receive a first hoof trim around 1 month after delivery.

Focus on nutrition

A mare’s first milk (colostrum) is rich in antibodies that help provide foals with passive immunity to help prevent disease while their immune systems fully develop. Visit the AAEP site for more information to ensure foals receive the right amount of colostrum needed to support their health.15

Deworm foals to control roundworms at 2 months

Roundworms are dangerous to foals in their first few months of life, so regular deworming is important to help prevent roundworms from working their way into a foal’s system. View our foal deworming guide (PDF).

4-6 months old

Prioritize nutrition and preventive care to help protect growing foals as they set out to explore new pastures and meet fellow herdmates.

Weaning Support

Weaning will vary for foals

Weaning typically occurs between the 4- and 7-month mark, once foals require additional nutrients from grain and forage.

Support mares during the weaning process

Mares should be turned out in a space where they can freely exercise. It’s also important to decrease grain rations for 7 to 10 days to facilitate drying up and prevent weight gain while they’re no longer producing milk for their foal.

Deworming

Deworm foals to control roundworms between 4 and 6 months

Your veterinarian can help provide a targeted deworming treatment plan tailored to your foal’s needs. 

View our foal deworming guide (PDF)

Vaccines

Foals initially get maternal antibodies from mares through colostrum found in milk, but as foals begin to wane, it’s important to protect them from common diseases with the right vaccines.

  • Core vaccinations between 4 and 6 months: The AAEP recommends foals receive their first dose of vaccines to protect against the five core diseases:  Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE), West Nile virus (WNV), tetanus and rabies.
  • Risk-based vaccinations between 4 to 6 months: The AAEP recommends foals receive a first dose against risk-based diseases like equine influenza (flu) and equine herpesvirus EHV-1 and 4 (rhino) during this time as well. Consult your veterinarian for additional risk-based vaccine recommendations based on your foal’s geography and other risk factors.

Weaning Care Tips

Focus on nutrition

Healthy young foals can gain nearly 3 lbs per day! Strive for balance when ensuring these 7- to 9-month-olds receive adequate nutrition to support their development. 

Build a strong foundation with hoof care

Continue hoof trimmings with a farrier on a monthly schedule to set them up for success now and down the road.

Deworming

Schedule your foal’s first fecal egg count (FEC) testing and continue deworming

Now is a great time to schedule FEC testing to help identify high shedders. 

  • If evidence of roundworms is detected, deworm to control in addition to targeting strongyles and tapeworms.

View our foal deworming guide (PDF).

Vaccines

Ask about booster vaccine options

Consult your veterinarian to schedule vaccine boosters (4 to 6 weeks following the first doses) to help protect foals against the five core equine diseases (EEE, WEE, WNV, tetanus and rabies). 

  • Check with your veterinarian to see if your foal should be vaccinated for risk-based diseases that include equine influenza (flu) and equine herpesvirus EHV-1 and 4 (rhino)

View our foal vaccine guide

10-12 months old

So much growth occurs in your foal’s first year of life, and now is the time to schedule proactive care visits ahead of their next developmental chapter as a yearling.

Weaning Care Tips

Plan for a dental exam

Foals are getting their first molars and may have sharp enamel points around this age. A routine dental appointment may help foals feel more comfortable.

Deworming

Deworm foals to target strongyles at 12 months

At 12 months, foals require another deworming treatment to control strongyles. Your veterinarian can help provide a targeted deworming plan tailored to your foal’s needs.

View our foal deworming guide

Vaccines

Schedule the third dose for certain vaccines

One year after foaling typically signifies the time for yearlings to receive a third dose of core- and risk-based vaccines. Discuss optimal timing for this dose with your veterinarian. 

  • Core vaccinations: EEE, WEE, WNV, tetanus, rabies
  • Risk-based vaccinations: Equine influenza (flu) and equine herpesvirus EHV-1 and 4 (rhino). Consult your veterinarian for additional risk-based vaccine recommendations based on your foal’s geography and other risk factors.

Yearling Care Tips

Discuss nutritional support with your veterinarian

Incorporate a feed containing ample fiber, 14% to 16% protein, and a balance of 60% to 70% of the ration as concentrates and 30% to 40% of the ration as roughage. Measured by weight to ensure yearlings receive the proper nutritional to support their growth.

Deworming

Deworm yearlings

Schedule early grazing season deworming for young horses (1 to 2 years of age) that may be more susceptible to parasites and may require extra treatments.

  • In the spring, yearlings should receive two deworming treatments with varied timing based on your location.
  • Now is also a good time to schedule a fecal egg count (FEC) test. To learn when to deworm, view our yearling deworming guide (PDF).
Vaccines

Schedule vaccines

Once foals receive their first three doses of core and risk-based vaccines, they’re treated like adult horses and should receive annual revaccinations to protect against core and risk-based disease antigens.

  • Core vaccines: Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE), West Nile virus (WNV), tetanus and rabies
  • Risk-based vaccines: Influenza (flu) and equine herpesvirus EHV-1 and 4 (rhino), plus any additional vaccinations recommended by your veterinarian based on your yearling's location and lifestyle
  • Learn more about vaccines by viewing our adult vaccination guide (PDF).

16-18 months old

Provide yearlings with optimal care and support through regular wellness exams, proper nutrition and exercise. These steps will help ensure they remain healthy, comfortable and ready to take on the world.

Yearling Care Tips

Schedule annual wellness exams

Work with your equine practitioner to develop a care plan to ensure your yearling is getting the care he needs, from regular dewormings and vaccinations to proper nutrition and exercise. 

Focus on exercise

Yearlings benefit from daily free-choice exercise, ensuring they’re not confined inside more than 10 hours a day and avoid any excessive or forced exercise to avoid sprains in joints or limbs.

Deworming

Stay current on deworming

Young horses are more susceptible to parasites, so they may require extra deworming. In late spring to early summer, yearlings should receive one to two deworming treatments depending on your climate and length of the grazing season.

View our yearling deworming guide (PDF).

19-21 months old

Provide thriving young yearlings with the utmost care by maintaining a consistent deworming and vaccination schedule. By being proactive, you can help protect them from potential illnesses.

FAQs

What vaccines are recommended for my mare prior to breeding?

If you’re planning to breed your mare, it's important to ensure she’s first protected against certain diseases by staying current on annual vaccinations. 

Zoetis aligns with the American Association of Equine Practitioners’ (AAEP) vaccination recommendation  to protect horses against these five core equine diseases.

• Eastern equine encephalomyelitis (EEE)
• Western equine encephalomyelitis (WEE)
• West Nile virus (WNV)
• Tetanus
• Rabies 

The AAEP also advises to consider any risk-based diseases that may impact your horse due to her age, location and interaction with other horses are current before breeding.14 Contact your veterinarian to schedule your horse’s core disease vaccines and discuss any necessary risk-based vaccines.

What vaccines does my mare need prior to foaling?

During pregnancy, it is important to protect broodmares with recommended vaccines to protect against diseases that could pose a risk to your pregnant mare. Broodmares should be vaccinated against equine herpesvirus type 1 (EHV-1), also known as equine rhinopneumonitis, at 5, 7 and 9 months of gestation to help limit the risk of abortion. 

You should consider an annual revaccination for your broodmare against equine leptospirosis (Leptospira interrogans) based on risk. Equine leptospirosis can present clinically as abortion, equine recurrent uveitis (ERU) or renal disease. A veterinarian may recommend a botulism vaccine based on your location to protect against botulism (Clostridium botulinum toxin).

Also, an equine rotavirus vaccine at 8 months’ gestation and a second and third dose in 4-week intervals thereafter for pregnant mares can provide the passive transfer of antibodies to foals to help protect against equine rotavirus, a viral diarrhea that affects foals.

Finally, in prep for foaling, your broodmare should get a booster to protect against the five core equine disease antigens approximately 4 to 6 weeks prior to giving birth so that she can pass immunity on to her foal through the colostrum (the first milk rich in maternal antibodies).14

For more information on vaccination recommendations for broodmares, see our guide based on AAEP Guidelines (PDF).

How long is a mare in labor?

During labor, be prepared to time each stage accurately by keeping a watch or clock nearby and have your veterinarian’s phone number on hand so you can quickly call if you have any concerns. Labor is divided into three stages (typically within 1-4 hours), and knowing the duration of each stage can help you monitor your mare’s progress.

1. During the first stage of labor, the mare my lie down, get up, sweat and seem uncomfortable. This stage can last several hours, and while there’s typically no need for intervention, call your veterinarian if you have any concern.

2. The second stage includes water breaking through delivery. This stage begins with the rupture of the chorioallantoic membranes, which are white, and ends when the foal is delivered, usually within 15 to 30 minutes. Keep an eye on the mare’s progress and call your veterinarian if you notice any difficulties, if the foal hasn’t been delivered within an hour or if you see red membranes instead of white surrounding the foal. 

3. The third and final stage is the passing of the placenta, which usually happens within 3 hours post-birth. If this is delayed, contact your veterinarian. Save the placenta in a covered bucket or plastic trash bag to keep it moist. Your veterinarian will want to examine it during the post-foaling physical exam to confirm the entire placenta has passed and check for any abnormalities.

When should I seek immediate help from a veterinarian when my mare is foaling?

Please pay close attention to these emergency scenarios that require immediate veterinary assistance:

• Emergency Scenario: If the membrane protruding from the mare’s vulva is red instead of white, carefully cut it with scissors (being careful not to cut the foal) and call your veterinarian immediately. This is a “red bag” delivery, which indicates the placenta has detached too early and is depriving the foal of oxygen.

• Emergency Scenario: Call your veterinarian if your mare doesn’t pass the placenta within 3 hours. A retained placenta, even a small tag, can cause infection, septicemia and possibly laminitis.

• If you notice any abnormal progress in any of the three stages of labor or have any concerns, it is crucial to call your veterinarian immediately to seek medical attention.

If the foaling process goes smoothly with no emergencies, here are a few tips for supporting mom and newborn.

Ideally, if all stages have progressed normally, it’s time to leave your mare and her newborn foal in peace. Once the foal is delivered and everyone is doing well, observe them from outside the stall to allow mom and newborn to bond. There’s no need to rush in and disturb the pair. Also, allow the umbilical cord to break naturally when the mare or foal stands. This is preferred over cutting the umbilical cord.

When should I deworm my pregnant mare?

Most adult horses, including broodmares, should receive two anthelmintic treatments (dewormers) per year to help control highly dangerous parasites, including small strongyles and tapeworms.13,16,17 The first dose should address small strongyles during the early grazing season (spring), and the second should address small strongyles and tapeworms during the late grazing season (fall).13 Ask your veterinarian for a fecal egg count (FEC) test to understand if your horse is a high shedder that may require additional anthelmintic treatments.

Quest® Gel (moxidectin) and Quest® Plus Gel (moxidectin/praziquantel) are the only commercially available equine dewormers that target the most threatening parasites, including encysted small strongyle larvae and bots, in a single dose.* Quest Plus Gel includes an additional active ingredient that treats tapeworms. Both have been evaluated as safe for use in breeding and pregnant mares. Take our deworming product quiz to find the right deworming treatment for your horse.

IMPORTANT SAFETY INFORMATION:
Do not use Quest Gel or Quest Plus Gel in foals less than 6 months of age or in sick, debilitated and underweight horses. Do not use in other animal species, as severe adverse reactions, including fatalities in dogs, may result. Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.

How do I prepare for foaling?

Preparing for the arrival of a new foal can be both exciting and nerve-wracking as a horse owner. Preparation can make all the difference in ensuring a safe and successful foaling process. Here are tips on how to prepare for foaling. 

First and foremost, it’s important to set up your barn and monitoring equipment well in advance of the due date. This includes installing cameras to monitor each stage of delivery, ensuring a clean and safe foaling stall, making sure there are no hooks or items the foal can get hurt on, and providing adequate bedding so the mare and foal can get up and down safely without injury. Stock up on necessary supplies such as clean towels and dilute cholorohexidine solution, and prepare a foaling kit. See a recommended foaling kit list in this article.

It's also crucial to find a safe place for your mare to foal. This should be a quiet and calm area, away from other horses and distractions.  

In case of an emergency, have your veterinarian's number on hand and be prepared to call them within 24 hours of the foal's arrival. 

Make sure you know the breeding date so you can accurately predict when your mare is going to foal. Your veterinarian can also check her milk calcium when you see the udder enlarge or the tips of the teats wax up. This can give you some indication about when she might foal.

What’s the 1-2-3 rule of foaling?

The 1-2-3 rule of foaling is a simple guideline stating that a foal should stand within 1 hour and nurse within 2 hours of foaling, and the mare should pass her placenta within 3 hours of foaling.  

If any of these milestones are missed, contact your veterinarian immediately. Foals should also be able to rise on their own and nurse at least every 30 minutes. By monitoring your foal's behavior and knowing the 1-2-3 rule, you can help ensure your newborn foal is healthy and developing properly. 

When should I start deworming my foal?

Foals require special deworming care during their first year of life, including a series of deworming treatments throughout year 1 with a focus on protecting against roundworms (ascarids), a parasite that can be targeted with a benzimidazole drug at 2 to 3 months of age.13 Once foals turn 4 to 6 months of age, it’s important to seek veterinary guidance to treat for strongyles and tapeworms based on your geographic region and when your foal was born.13 

Note that additional treatments may be advised before weaning if the time period between both doses exceeds 3 months.

It’s also beneficial to schedule a fecal egg count (FEC) test with your veterinarian once weaning begins to help narrow down a recommended treatment option to better understand which parasite poses the greatest risk (primarily strongyles or ascarids) to your foal.16 

The next 2 deworming doses are advised between 9 and 12 months of age to target strongyles. However, in regions where tapeworms pose a threat, using a tapeworm treatment at 9 months or before the next calendar year is advised.13

Please see the following resources to learn more about recommended deworming treatment plans.
