How to Stimulate Your Sow to Start Milking After Farrowing

A sow that fails to produce adequate milk after farrowing is one of the most urgent emergencies in pig farming. Piglets are born with almost no energy reserves - they must nurse within 30 minutes of birth or their blood sugar drops dangerously. If the sow is not producing milk, every piglet in the litter is at risk of death within 6-12 hours. This condition, called agalactia (no milk) or hypogalactia (insufficient milk), affects 5-10% of sows after farrowing. Knowing how to respond quickly and effectively can save a litter worth 360,000-720,000 FCFA (~$1200) [VERIFIED: 8-12 piglets × 45,000-60,000 FCFA (~$100) weaner price].

Why Sows Stop Producing Milk

Understanding the cause helps you choose the right treatment. The 4 most common causes are: (1) Mastitis - bacterial infection of the mammary gland, usually from unsanitary farrowing conditions. The gland becomes hot, swollen, and painful. (2) Retained placenta or uterine infection - causes systemic illness and suppresses oxytocin release. (3) Stress - farrowing in a strange environment, excessive noise, or rough handling inhibits milk let-down. (4) Dehydration - a farrowing sow needs 25-30 liters of water; without it, she cannot produce milk.

7 Techniques to Stimulate Milk Production

1. Oxytocin injection (fastest method)

Inject 10-20 IU of oxytocin IM in the neck. Oxytocin is the hormone that triggers milk let-down. It works within 5-10 minutes. This is the fastest and most reliable method. However, oxytocin only works if the mammary gland has milk that is not being released - it does not create milk from nothing. If the gland is completely empty (true agalactia), oxytocin will not help. Repeat every 2 hours for up to 3 doses. Cost: 500 FCFA (~$0.83) per dose.

2. Udder massage (natural method)

Gently massage the sow's udder with warm water (38-40C) for 5-10 minutes. Use a clean cloth soaked in warm water. The warmth and pressure stimulate oxytocin release naturally. Do this 3-4 times per day. This is also good for detecting mastitis - if the sow reacts painfully to touch on one teat, that gland may be infected.

3. Piglet stimulation (the natural oxytocin trigger)

Piglets nursing is the most powerful natural stimulant for milk let-down. If piglets are too weak to nurse, express some colostrum manually (squeeze the teat gently) and feed it to the piglets with a syringe (no needle). Once they have energy from the colostrum, they will be strong enough to nurse, which stimulates more milk production. It is a positive feedback loop.

4. Warm water + electrolytes

Dehydration is a major cause of agalactia. Offer the sow 5 liters of warm water with 2 tablespoons of salt and 4 tablespoons of sugar (basic electrolyte solution) immediately after farrowing. Repeat every 4 hours for the first 24 hours. A hydrated sow produces milk; a dehydrated sow does not.

5. Antibiotics for mastitis

If the udder is hot, swollen, or painful, the sow likely has mastitis. Inject a broad-spectrum antibiotic: Penicillin-Streptomycin (10ml IM) or Enrofloxacin (2.5mg/kg IM) for 3-5 days. Mastitis will not resolve without antibiotics - the infection blocks milk ducts and produces toxins that suppress milk production. Cost: 2,000-5,000 FCFA (~$8.33) for a full course.

6. Dexamethasone for inflammation

If the udder is severely inflamed, inject 5-10mg dexamethasone IM (anti-inflammatory). This reduces swelling and allows milk to flow. Use only once - repeated use suppresses the immune system. Cost: 500 FCFA (~$0.83) per dose.

7. Artificial rearing (last resort)

If the sow cannot produce milk within 6 hours despite all treatments, you must artificially rear the piglets. Use commercial milk replacer (or cow's milk with 1 egg per liter + 1 tablespoon sugar). Feed 20ml per piglet every 2 hours for the first 3 days, then every 4 hours. This is labor-intensive but saves piglets that would otherwise die. A piglet feeding bottle costs 2,000 FCFA (~$3.33); milk replacer costs 8,000-12,000 FCFA (~$20.0) per kg.

Prevention is always better than treatment. Ensure the sow is well-hydrated during farrowing, farrow in a clean disinfected pen, reduce stress, and feed a balanced lactation ration (6-8 kg/day for a sow with 12+ piglets). FarmWise tracks farrowing dates and generates reminders for post-farrowing health checks, so you can catch agalactia early before piglets start dying.
