Newborn Foal Care – The Critical First 24 Hours

A foal's first day sets up the rest of its life. Horses are prey animals, and a newborn has to make an enormous leap in a few short hours: from floating in a womb to standing, nursing and being ready to run. Good newborn foal care is mostly about knowing what normal looks like, watching closely, and picking up the phone early when something is off.

This guide covers the run-up to foaling, the three stages of labour, the milestones every foal should hit, and the problems that need a vet on the yard fast.

Preparing for Foaling

How Long Does a Mare Carry a Foal?

Average gestation runs between 335 and 345 days, with a normal range of roughly 320 to 360 days. Counting 335 days from the last breeding date gives you a practical due date, and starting your watch a little early is better than being caught out.

A foal born before day 320 is considered premature and will almost certainly need veterinary support. Pregnancies that stretch past 360 days can also cause trouble. In South Africa, mares grazing endophyte-infected fescue are a particular risk for prolonged gestation, weak foals and poor milk production, so that grazing should be removed 45 to 60 days before the due date.

Signs Your Mare Is Close

The udder usually starts filling two to four weeks out. Around one week to a month before foaling, the muscles around the tailhead relax and the belly drops. Two to six days out, the teats fill properly. One to four days before delivery, small honey-coloured beads of colostrum appear on the teat ends, which is known as waxing.

The most reliable predictor is milk calcium. When mammary calcium rises above 200 ppm, there is roughly an 84% chance the mare will foal within 48 hours. Test kits for mare's milk are available through your vet, and some breeders use water hardness strips as a rough substitute.

Call your vet if your mare has a vaginal discharge, develops an udder far too early, or starts streaming milk well before her time. These can point to placentitis or a compromised pregnancy.

Setting Up the Foaling Space

Mares almost always foal at night, in the quietest place they can find. If she is disturbed during early labour, she can simply stop and wait.

Move her to the foaling location about a month in advance so she builds immunity to that environment, then into the actual foaling stall a few days to a week before her due date. The stall should be at least 4.3 x 4.3 metres, though 5 x 5 is better. Bed it deeply with straw rather than shavings, because small particles collect around the foal's nostrils and can be inhaled.

Strip the stall completely between foalings and disinfect it. Wash the mare's perineum and udder, and wrap the top half of her tail. If she has had a Caslick's procedure, it must be opened before she foals.

What to Keep in Your Foaling Kit

Put together a stall-side kit well in advance. It should include clean towels, exam gloves, a tail wrap, a clean wash bucket, and dilute chlorhexidine or iodine for dipping the navel. Add a thermometer, a weight tape, scissors, and a notebook and pen for writing down times.

A heavy-duty black plastic bag is useful for saving the placenta for your vet. A store-bought enema, a foal bottle with a lamb nipple and a 35 ml oral syringe are worth having on hand. If your vet recommends it, a refractometer lets you check colostrum quality before the foal drinks it.

The Three Stages of Labour

Stage One

Stage one is the onset of uterine contractions and typically lasts one to five hours. The mare becomes restless and often looks colicky. She may pace, sweat, switch her tail, circle, lie down and get straight back up, or bite at her flanks.

Write down when it starts. Emotions run high at a first foaling and time gets away from people. Stage one ends when the water breaks in a rush of allantoic fluid.

Stage Two

Stage two is the delivery itself, and it is quick: usually 15 to 30 minutes from the water breaking. This speed matters. The equine placenta detaches easily, and once it does the foal has no oxygen supply, so a long stage two is a genuine emergency.

The normal presentation looks like a dive. Both front feet come first, one slightly ahead of the other with the soles pointing down, followed closely by the nose lying on the legs. If you see hoof soles facing up, only feet with no nose after 15 minutes, or contractions that stop altogether, call your vet immediately.

Stage Three

Stage three is passing the placenta, and it should be complete within three hours. Save it in a bucket or bag so your vet can weigh it and check it is intact. A normal placenta weighs about 10 to 11% of the foal's birth weight, and a heavy one can indicate infection.

A retained placenta, even a small tag left behind, can cause a severe uterine infection, laminitis or death. Three hours is the deadline, not a suggestion.

Red Bag Deliveries and Resuscitation

Recognising a Red Bag

The membrane that appears at the vulva should be white and translucent. If it is red and velvety, the placenta has separated prematurely and the foal is suffocating. Cut the bag open immediately, taking care not to cut the foal, deliver the foal as fast as you can, and call your vet while you work.

If the Foal Is Not Breathing

Clear the nostrils first. Horses breathe only through their noses, so mucus or membrane over the nostrils has to come off within a minute of birth.

Newborn foals breathe fast at first, around 60 to 80 breaths a minute in the first half hour, settling to 30 to 40 by the end of the first day. If the foal is not breathing, lay it down, extend the neck, close one nostril and the oesophagus with your thumb behind the throatlatch, and breathe into the other nostril 10 to 20 times a minute. Closing the oesophagus stops air filling the stomach.

Ventilation matters more than compressions, because respiratory arrest comes first in large animals. If the heart rate stays below 60 beats a minute after ventilation is going well, add compressions behind the shoulder at about 100 beats a minute.

The 1-2-3 Rule of Newborn Foal Care

The simplest framework for the first few hours is the 1-2-3 rule.

Stand Within One Hour

The foal should be making serious attempts to rise within about 30 minutes and should be standing within an hour. A foal still down at two hours needs veterinary attention. Sometimes the problem is mechanical rather than systemic, such as contracted tendons, but the outcome is the same: a foal that cannot stand cannot nurse.

Nurse Within Two Hours

Watch the actual nursing, not just the foal standing near the udder. You want to see the tongue seal around the teat and hear swallowing. Milk running out of the nostrils suggests dysphagia or a cleft palate and needs a vet.

A healthy foal nurses often, roughly three to seven times an hour, sometimes more, for a minute or so at a time. Check the mare's udder regularly. A tight, over-full udder or milk streaming down her legs usually means the foal is not drinking.

Placenta Within Three Hours

The third part of the rule belongs to the mare. Nursing stimulates the contractions that help her pass the afterbirth, so the three milestones are linked.

Colostrum and Passive Transfer

Foals are born with no working immunity of their own. Everything protecting them for the first six to twelve weeks comes from colostrum, the mare's first milk.

Why the Clock Matters

A foal can only absorb antibodies through the gut wall for the first 18 to 24 hours, with peak absorption in the first six to twelve. After that the window closes permanently, regardless of how much the foal drinks.

Aim for at least a litre of good-quality colostrum in the first hours, with two to three litres over the first six to eight hours being ideal for an average foal. Colostrum tested on a Brix refractometer should read above 30%. Below 20% is not good enough, and you will need a frozen back-up supply or a donor.

Testing IgG

Your vet will draw blood at 12 to 24 hours to measure IgG. Above 800 mg/dl is normal. Below 400 mg/dl is failure of passive transfer and calls for supplemental colostrum or an intravenous plasma transfusion. Between 400 and 800, the foal is usually retested or treated to be safe.

Bottle-feeding is not the answer to a foal that will not nurse. The aspiration risk is high and pneumonia follows. Your vet will tube the foal instead.

Navel Care and Meconium

Handling the Umbilical Cord

Leave the cord alone. It usually breaks on its own as the mare or foal stands, and blood keeps flowing to the foal until it does. If it has stopped pulsing and has not broken after a few minutes, hold it firmly on either side about 2.5 cm from the foal's belly, then twist and pull.

Never cut it. Twisting and tearing helps the vessels seal, while a clean cut bleeds.

Dipping the Navel

The stump is an open door into the foal's bloodstream. Dip it in dilute chlorhexidine or a weak iodine solution shortly after it breaks, then two to four times daily for the first two to three days until it dries.

Watch it closely. A navel that stays wet, feels hot, swells, discharges or drips urine needs a vet. Dripping urine points to a patent urachus.

Passing the Meconium

Meconium is the dark, firm first manure formed in the womb. Most foals pass it within 8 to 12 hours, and it should be complete by 24 hours. After that, manure turns soft and light tan.

Straining, restlessness and constant tail switching suggest an impaction. Your vet may advise a single enema, but do not repeat it more than once or twice, since too many enemas irritate the colon. Colts should urinate within about six hours; fillies often take longer.

Normal Vital Signs for a Newborn Foal

Temperature should sit between 37.2 and 38.6 °C. Foals cannot regulate their own temperature well, so cold weather affects them quickly.

Heart rate runs 80 to 120 beats a minute once settled, though it can swing between 60 and 130 in the first hour. Respiration is 20 to 40 breaths a minute at rest after the first half hour.

Birth weight is around 10% of the mare's mature weight, and height about 60%. An average Thoroughbred or Quarter Horse foal weighs between 36 and 50 kg.

Healthy foals cycle between nursing, resting and exploring. A curious foal that stays close to its dam is a good sign. A dull, flat foal that does not get up is not.

Common Problems in the First Weeks

Neonatal septicaemia, prematurity, dummy foal syndrome and fractured ribs are the most serious early conditions and usually need hospital care. Meconium impaction, umbilical infection, neonatal isoerythrolysis, ruptured bladder, pneumonia and diarrhoea round out the list.

Joint ill, where bacteria settle in the joints, shows up as lameness, swelling over one or more joints, fever and lethargy. Limb problems are common too, and your vet will check whether the fetlocks are dropped or the foal is walking on its toes. Most cases respond to controlled exercise, splints or corrective shoeing rather than surgery.

The first sign of nearly all of these is the same: a foal that seems dull and nurses less, paired with an over-full udder on the mare.

Watching the Mare

Poor mothering is more common than people expect, especially with maiden mares. Watch for a mare that will not bond, is frightened of the foal, is aggressive towards it, or walks away every time it tries to nurse.

A first-time mare often finds nursing strange or sore, and simply haltering her while the foal latches can solve it. If she squeals and kicks, your vet may prescribe an anti-inflammatory. True rejection needs veterinary help quickly, including hormone protocols, and you need a plan for milk replacer or a nurse mare if it fails.

The First Veterinary Visit

Book an exam within 12 to 24 hours, sooner if anything about the birth was unusual. Call your vet as well if the foaling was unassisted and nobody saw it happen.

The vet will check temperature, pulse and respiration, examine the eyes, mouth and nose, listen to the heart and lungs, palpate every joint, assess the limbs for deformity or laxity, check the umbilicus, and confirm the foal is urinating and passing manure. Bloods go off for IgG and infection markers. Many vets give a vitamin E and selenium injection. The mare gets her own post-foaling exam at the same time, including a check for vaginal or cervical tearing.

Keeping the First Weeks Simple

Hygiene does most of the work. Keep bedding dry and deep, strip wet patches promptly, use clean towels and buckets, and keep dogs, visitors and general chaos away from the pair.

Turn the mare and foal out within a couple of days, and into a paddock with other lactating mares within a week. Handle the foal calmly and briefly rather than in long sessions, and teach manners without roughness.

Vaccination timing depends on the mare. Foals from vaccinated mares usually start at six to nine months, because earlier doses are blocked by maternal antibodies. Foals from unvaccinated mares start at three to four months.

A newborn can go from bright to critical in a few hours, so waiting to see how it goes is the one thing that costs you time you cannot get back. If the foal does not look right, trust that feeling and call your vet.
