Difficult Farrowing: What to Do When the Sow Can't Deliver

"Kung dugay na kaayo og wala pa mogawas ang baktin, kinahanglan ka molihok." (If it's been too long and no piglet has come out, you need to act.)

Most sows farrow 8 to 12 piglets over 1 to 5 hours with no help, but if she strains 45 minutes with no piglet, or 60 minutes with no contractions at all, intervene. About 47% of farrowings hit some difficulty. A stillborn piglet is ₱2,000 to ₱5,000 in lost revenue. A dead sow is ₱15,000 to ₱25,000.

What Normal Farrowing Looks Like

Before you can recognize abnormal, you need to know normal. According to the NADIS farrowing guide:

Piglets can come head-first or tail-first. Both are normal. Just under half are delivered tail-first, so a backward piglet is not the emergency it would be in cattle. Don't panic about it. What matters more is the clock: once the gaps between piglets stretch past 15 minutes, the odds of the next one being stillborn climb, and a sow that hits 45 minutes with nothing has crossed from "slow" to "stuck."

When Something Is Wrong: The Red Flags

Don't wait hours "to see if she figures it out." A sow that has been straining unproductively for 45 minutes needs help. The piglets behind the stuck one are running out of oxygen.

Which Sows Are Most at Risk?

Not all farrowings are equal. According to a 2021 study on dystocia risk factors in swine, about 6% of piglets are born with a dystocia event and 47% of farrowings have at least one difficulty. Worth flagging: that same study found the strongest predictors were oversized piglets (crown-rump length over 31 cm roughly doubled the risk) and the presence of dead or mummified piglets in the litter. It did not find a significant link to sow parity or body condition on its own. The risk factors below are still worth watching from field experience, but the hard data points hardest at piglet size and a litter that already has dead piglets in it.

If your sow checks multiple boxes (first-time gilt AND bred to a large boar, for example), plan to be present for the entire farrowing. Don't check at midnight and go back to sleep. Stay.

The Money at Stake

A difficult farrowing that you don't handle costs more than you think:

• Each stillborn piglet: ₱2,000-₱5,000 in lost future revenue (a piglet that would have become a ₱16,000-₱19,000 market pig)
• Dead sow from uterine rupture: ₱15,000-₱25,000 replacement cost for a proven breeding sow
• Vet emergency call (if you waited too long): ₱1,000-₱3,000
• Your emergency supply kit: ₱250-₱500

Spend ₱250-₱500 on preparation to protect ₱50,000+ in sow and piglet value. That's the math.

Preparing the Farrowing Area

Set this up 3-5 days before the sow's due date. A sow that farrows in a clean, warm, calm environment has fewer complications.

• Clean and disinfect the pen. Scrub with soap, apply lime wash or diluted bleach, let dry completely. A dirty farrowing pen is the most common reason a sow that farrowed fine still ends up with metritis or mastitis a few days later.
• Bedding. Clean rice straw or shredded paper. Not sawdust (clogs piglet airways). Not nothing (concrete is too cold for newborns).
• Piglet creep area. A warm corner with a heat lamp (₱80-₱200) or 100W bulb where piglets can warm up between nursing. Keep it 30-35°C.
• Guard rails. If your pen has solid walls, install a rail 20-25 cm from the wall at 20 cm height. This prevents the sow from crushing piglets against the wall when she lies down. A bamboo pole wired to the wall works.
• Water for the sow. Fresh, clean, ad libitum. Dehydrated sows have weaker contractions and produce less milk. Nipple drinker or clean bucket.

If you're breeding regularly, read our guides on how to tell when your sow is in heat and how to tell if your pig is pregnant for the full reproductive cycle leading up to this day.

Step-by-Step: How to Assist

This is the part most guides skip because it's messy and scary. But it's not complicated. Farmers across Visayas and Mindanao do this routinely.

Before You Start

1. Wash your hands and arms thoroughly with soap and water. Clip and clean under your fingernails. A long nail can tear the birth canal, and a tear is how metritis starts. Pork Information Gateway is blunt about this: any internal exam raises infection risk, so go in clean or not at all.
2. Put on a clean OB sleeve if you have one (arm-length glove, agri-vet stores, ₱10-₱25 each). A sleeve is genuinely better than bare hands here, not just a nicety. If you truly have none, bare scrubbed hands and short nails are the fallback, but understand you are accepting a real metritis risk to save the litter.
3. Apply lubricant generously. Use OB lube (₱80-₱150 per tube from agri-vet), or clean cooking oil, or coconut oil (lana sa lubi) if that's what you have. Do NOT use soap or detergent as lubricant. Soap dries out and irritates the tissues and causes swelling, which makes the next piglet harder to deliver.
4. Keep the sow calm. Talk to her quietly. Don't shout or rush. A stressed sow clamps down harder.

The Procedure

1. Cup your hand into a cone shape (fingers together, pointed).
2. Gently insert your hand into the vulva in an upward direction. Go slowly. The birth canal curves upward and forward.
3. Feel for the piglet. You may feel a head (snout, ears) or hind legs (two small legs close together). Both are normal presentations.
4. If you can feel the piglet: Grasp it gently. For a head-first piglet, hook your fingers into the mouth with your thumb under the jaw, or cup the head. For tail-first, grasp both hind legs together.
5. Pull gently and slowly, timed with the sow's contractions. Pull slightly downward (toward the sow's belly, not straight out). Never yank. Gentle, steady traction. If it doesn't move, re-lubricate and try repositioning.
6. Once the piglet is out: Clear the membrane from its face immediately. Wipe the nose and mouth. If it's not breathing, rub the chest vigorously with a dry towel. Swing it gently (head down, legs held) to drain fluid from the airways. Give it to a warm, dry area.
7. Go back in if you think more piglets are stuck. The next one may be right behind.
8. After any manual assist, plan for infection. A sow that has had a hand or arm inside her is at higher risk of metritis and the full MMA picture (mastitis, metritis, agalactia) in the days after. Pork Information Gateway recommends a post-farrowing antibacterial measure when assistance was needed. Don't improvise this with random pharmacy antibiotics. Call your vet, tell them you assisted, and follow their cover-antibiotic and post-assist instructions. Take her rectal temperature twice a day for five days. Fever over 39.5°C means call the vet.

What If You Can't Reach the Piglet?

If your hand is fully inserted and you can't feel anything, the piglet may be deeper in the uterine horn. This is beyond manual assistance for most farmers. Call your vet. Oxytocin may be needed to restart contractions, or the sow may need a cesarean section.

Oxytocin: When and How (Vet Guidance Only)

Oxytocin is a hormone that stimulates uterine contractions. It can help when the problem is weak or absent contractions (uterine inertia) late in the litter, never when a piglet is physically blocking the way. This is the single most misused drug on a backyard farm, and the misuse kills piglets. Treat the rules below as hard rules, not suggestions.

Two things farmers get wrong constantly. First, the dose. The article you read somewhere that says "give a small amount" is useless without a concentration. Vet extension sources (Penn State, Kansas State, Pork Information Gateway) consistently recommend a low dose of about 20-30 IU, which is roughly 1 to 1.5 mL of common 20 IU/mL oxytocin. The reason it must stay low: the farrowing sow is already making her own oxytocin, so an extra 30-50 units stacks into an overdose. More is not better. More causes harm.

Second, the timing. Oxytocin given too early, before the cervix is fully open or before the first piglet is born, is documented to increase stillbirths. It does this by clamping the uterus down so hard that umbilical cords rupture and piglets lose their oxygen supply before they are out. That is the main documented danger, not just the worst-case uterine rupture.

A common field rule of thumb from extension vets: if 30 minutes have passed since the last piglet and you have confirmed there is no obstruction, that is the window oxytocin is meant for, not the start of farrowing. When in doubt, the answer is to call the vet, not to inject.

In most rural Philippine municipalities, getting oxytocin requires a vet prescription. Your municipal vet can provide or prescribe it, usually around ₱150-₱250 per 50 mL vial. Have it on hand before farrowing day only if your vet has briefed you on when and how to use it for that sow. This dosing is consistent with our MMA guide, which uses the same 10-20 IU range to force milk letdown after farrowing.

The Emergency Supply Kit (Have This Ready BEFORE Farrowing)

Don't scramble for supplies at 2 AM. Prepare this kit at least 1 week before the sow's due date. Total cost: ₱250-₱500.

Saving Weak or Unresponsive Piglets

Some piglets come out alive but barely. They need help in the first 60 seconds.

Not breathing:

1. Clear the mouth and nose of fluid and membrane
2. Rub the chest vigorously with a dry towel
3. Hold the piglet by the hind legs and swing gently downward (this drains fluid from the lungs). Be careful not to drop it.
4. If still not breathing, give gentle mouth-to-snout resuscitation. Cover the piglet's nose and mouth with your mouth, give tiny breaths. Sus, it works.
5. Keep trying for 2-3 minutes. Some piglets revive after what looks like too long.

Cold and weak (born alive but fading):

1. Dry thoroughly with a towel. Wet piglets lose heat fast, and hypothermia kills within hours.
2. Place under heat lamp or in a warm box (30-35°C). A cardboard box with a 100W bulb and towels works.
3. Get colostrum into the piglet within 6 hours of birth. If the piglet is too weak to nurse, milk the sow by hand and feed with a syringe (no needle). Colostrum provides antibodies. Without it, the piglet has almost no immune protection.

Post-Farrowing Complications to Watch For

These three (retained placenta, mastitis, agalactia) often arrive together as MMA after a hard farrowing. We have a full protocol in the MMA guide; the short version is below. The single most useful number: a rectal temperature over 39.5°C in the first 48 hours after farrowing means call the vet today, don't wait.

Retained Placenta

If the placenta hasn't passed within 4-6 hours after the last piglet, it may be retained. Signs: foul-smelling vaginal discharge, fever, reduced appetite. Call your vet. A retained placenta drives uterine infection (metritis), which can be fatal and which an assisted farrowing makes more likely.

Mastitis (Infected Udder)

Hot, swollen, hard teats. The sow is in pain when piglets try to nurse, runs a fever, and goes off feed. Piglets are restless and hungry because they can't get milk. Treatment is vet-prescribed antibiotics plus an anti-inflammatory, with hand-milking to relieve pressure. Common when the farrowing area was dirty. The MMA guide has the specific antibiotic and oxytocin-for-letdown protocol.

Agalactia (No Milk)

The sow farrowed but has no milk or very little. Piglets are hungry, loud, and losing weight fast. It can come from stress, infection, or hormonal problems and usually travels with the mastitis and metritis above. If there is no milk within 12 hours of farrowing, find a foster sow or start syringe feeding. A PH backyard milk recipe and feeding volumes are in the MMA guide; commercial milk replacer runs ₱300-₱500 per kg at agri-vet stores.

Savage Sow (Postpartum Aggression)

Some sows become aggressive toward their piglets after farrowing, especially first-time gilts, and a painful dystocia makes it more likely. She may bite or lunge at the piglets. Get the piglets out to a warm box first, then deal with the sow. The standard vet sedation for this is azaperone (Stresnil), not "holding her down." We cover the dose and the cull-on-second-litter rule in the savaging gilt guide.

When to Call the Vet (Not a Suggestion, A Decision)

Municipal vets in most Visayas and Mindanao towns are reachable by phone, even at night for emergencies. Save the number in your phone before farrowing day. In Cebu, Iloilo, and Davao, there are usually private large-animal vets available. In more remote municipalities in Leyte, Bohol, or interior Bukidnon, you may need to rely on your barangay livestock aide or an experienced neighbor. Not ideal, pero mas maayo nga naay kahibalo kaysa mag-inusara.
