Complete Foaling Kit: Vet-Approved Supplies

A well-stocked foaling kit can mean the difference between life and death for your mare and foal. This veterinarian-approved guide covers every essential supply, emergency item, and critical timeline you need for a safe delivery in 2026.

Complete Foaling Kit: Veterinarian-Approved Supplies and Emergency Essentials

A complete foaling kit should be assembled and ready at least 2-4 weeks before your mare's due dateBecause foals don't wait for you to run to the store. Whether you're an experienced breeder or preparing for your first foaling season, having the right supplies on hand is the single most controllable factor in a successful outcome.

What Is the 1-2-3 Rule and Why Does It Matter?

Before assembling your kit, internalize the 1-2-3 Rule, the gold standard benchmark used by equine veterinarians worldwide to assess whether a foaling is progressing normally:

  • 1 hourFoal should stand
  • 2 hoursFoal should nurse
  • 3 hoursMare should pass the placenta

If any of these milestones are missed, consider it a veterinary emergency. Placenta retention beyond 6 hours can trigger endotoxemic shock and dramatically increase laminitis risk in the mare. Keep your veterinarian's after-hours number in the kit itself, not just in your phone.

What Should Go in a Foaling Kit?

Organize your supplies into four categories: mare care, foal care, monitoring, and emergency.

Mare Care Supplies

ItemPurposeNotes
Tail wrap / bandageKeep tail clean during deliveryApply in Stage 1 labor
Bucket and warm waterCleansingHave 2 clean buckets ready
Mild soap (Betadine scrub)Perineal washDilute before use
Twine or baling stringTie up placentaNever cut or pull the placenta
Large clean towels (×4+)Drying the foalRough texture stimulates breathing
OB lubricantAssistance with dystociaOnly if vet-directed
Digital thermometerMare temp monitoringNormal: 99–101°F (37.2–38.3°C)
Oxytocin (Rx only)Aid placental expulsionStored per vet prescription
Clinical note:Never manually remove a retained placenta, as this can cause life-threatening hemorrhage. Tie the placenta up in a knot so the mare doesn't step on it, and call your vet.

Foal Care Supplies

ItemPurposeNotes
Dilute iodine solution (iced-tea color) or 1:4 ChlorhexidineUmbilical stump disinfectionApply 2–3× daily until dry; avoid straight iodine — scalding risk
Small cup or dip cupUmbilical dippingDedicated to this use only
Fleet enema (sodium phosphate)Meconium clearanceFoal should pass within 8 hours
Foal blanketThermoregulationEspecially for cold climates
Colostrum (banked, frozen)Passive immunity backupMinimum 2 liters in stock
Bottle and foal nippleSupplemental feedingIf foal won’t nurse
Nasogastric tube (12 French)Colostrum administrationVeterinary use; know how to assist

Monitoring Equipment

ItemPurposeClinical Threshold
Brix refractometerColostrum IgG quality>23% Brix = >60 g/L IgG (good); <15% = <30 g/L (supplement)
IgG test kit (SNAP test or lab)Passive transfer confirmationTest at 8–24 hours; >800 mg/dL = adequate
StethoscopeHeart rate, gut soundsFoal HR: 60–80 bpm at rest
Flashlight / headlampNight foalingHands-free preferred
Baby scale or weight tapeFoal birth weightAverage 10% of mare’s body weight
Watch or phone timerMilestone tracking1-2-3 Rule enforcement

Emergency Items

  • Scissors (sharp, bandage scissors)Critical for Red Bag deliveries. If the chorioallantois appears at the vulva instead of the glistening white amnion, cut it immediately. This is a time-sensitive emergency: the foal is being deprived of oxygen.
  • Sterile gloves (long OB gloves and exam gloves)Multiple pairs
  • Halter and lead ropeFor the mare
  • Emergency vet contact cardPrimary vet + equine hospital within 60-90 minutes
  • Headstall lightBattery-powered for stall corners
  • Camera or phoneDocument placenta for veterinary review; it should weigh 3-5 lbs and be passed intact

When Should Your Foaling Kit Be Ready?

Most veterinary resources, including Colorado State University’s Equine Reproduction Laboratory, recommend that pregnant mares arrive at a foaling facility 2-4 weeks before their due date. Your kit should be fully assembled and stocked at the same time.

Use Breedio to track your mare’s gestation progress and set milestone alerts so you’re never caught unprepared. The Track Your Maresdashboard gives you a real-time countdown to foaling, accurate down to the day.

How Do You Assess Colostrum Quality?

Colostrum is the most critical substance your foal will ever consume. Foals are born immunologically naive, meaning 100% of their early immune protection comes from colostral antibodies ingested in the first hours of life.

Key thresholds from veterinary literature:

Brix ReadingIgG EstimateAction Required
>23% Brix>60 g/LExcellent; can bank surplus
20–23% Brix~40–60 g/LAdequate; ensure foal consumes all
15–20% Brix~30–40 g/LSupplement with banked colostrum
<15% Brix<30 g/LEmergency — need banked colostrum or substitute

The foal’s intestine is only permeable to immunoglobulins for the first 24 hours of lifePeak absorption occurs in the first 6-12 hours. After 24 hours, the gut closes and oral supplementation becomes ineffective; plasma transfusion is the only remaining option for failure of passive transfer (FPT).

A 50 kg foal needs at least 60 grams of immunoglobulinsRoughly 1.5-2 liters of quality colostrum within its first 12 hours. Confirm passive transfer with an IgG snap test or send a blood sample to your vet between 8 and 24 hours post-birth.

What Pre-Foaling Vaccinations Should Your Mare Receive?

Vaccinate your mare 30 days before foaling to maximize the antibody load transferred via colostrum. Per board-certified equine specialist guidance, the standard pre-foaling protocol includes:

  1. West Nile Virus
  2. Eastern/Western Equine Encephalomyelitis (EEE/WEE)
  3. Equine Influenza
  4. Tetanus toxoid
  5. Rotavirus(if your farm history warrants it, typically given at months 8, 9, and 10)

Foals receive maternal antibody protection until approximately 4-6 months of age, after which they'll need their own primary vaccination series.

What Are Red Flags During Foaling?

Know these warning signs: hesitation costs lives:

Call your vet immediately if:

  • No foal within 10-15 minutes of the amniotic sac rupturing
  • A red velvety membrane (chorioallantois) appears at the vulva before the white amnion: Red Bag delivery
  • Foal has not stood by 1 hour
  • Foal has not nursed by 2 hours
  • Placenta has not passed by 3 hours (retained placenta after 6 hours = emergency)
  • Foal appears weak, lethargic, or shows dummy foal signs (wandering, failure to seek the udder)
  • Foal’s mucous membranes are yellow within 12-48 hours (neonatal isoerythrolysis, affects 1-2% of foals)

How Do You Organize and Maintain Your Foaling Kit?

Practical organization matters at 2 AM in a dark stall:

  • Use a labeled, waterproof tote or hard case, not a cardboard box
  • Store in the foaling stall or tack room, not your house
  • Restock immediately after each use; expired items (iodine, test kits) should be replaced annually
  • Tape a foaling checklist and vet contact card inside the lid
  • Run a dry drill; walk through the kit with your farm manager or barn staff before the season starts

For breeders managing multiple mares, the Features page on Breedio shows how you can track gestation stages, set push notifications for approaching due dates, and log foaling observations, all in one place.

Summary: Your Foaling Kit at a Glance

A complete foaling kit includes supplies across four categories:

  1. Mare care: Tail wraps, warm water, Betadine, twine for placenta, thermometer
  2. Foal care: Dilute iodine or Chlorhexidine for the navel, Fleet enema, banked colostrum, foal blanket
  3. Monitoring: Brix refractometer, IgG snap test, stethoscope, stopwatch
  4. Emergency: Bandage scissors (Red Bag), OB gloves, vet contact card

Preparation isn't pessimism; it's professionalism. The breeders who sleep soundly during foaling season are the ones who assembled their kit weeks ahead of time, vaccinated their mares on schedule, and know exactly what to do when the alarm goes off. Track Your Mares with Breedio so that when the moment comes, the only thing you need to think about is your mare and foal.
