Most pig limping in the Philippines comes from six causes: a slip on a wet floor, a foot abscess, erysipelas, mycoplasma arthritis, Streptococcus suis, or rickets from rice-bran-heavy growing rations. About 80% of cases need either drainage, an injection, or a feed fix, not a vet visit. The hard part is telling them apart in the first ten minutes.
Should I Wait, Treat, Or Call The Vet?
Take the temperature first. Normal is 38.7-39.8°C; above 40.5°C is serious. A drugstore digital thermometer costs ₱150 and saves you a wrong diagnosis. Pair it with the table below and the signs your pig is sick guide.
| Sign | Likely picture | Action |
|---|---|---|
| One leg, no fever, still eating, after a slip or fight | Trauma | Rest 48h, dry bedding, NSAID |
| Hot swollen claw or coronary band, pus visible | Foot abscess | Drain, iodine flush, penicillin IM |
| Diamond or rectangular red skin patches plus fever | Erysipelas | Penicillin IM same day, or vet now |
| Weaner (3-10 wk), limping plus circling, head tilt, paddling | Streptococcus suis | Vet now. Use gloves. |
| 10-30 wk pig, swollen joint, NO fever, eating normally | Mycoplasma arthritis | Tylosin or lincomycin (NOT penicillin) |
| Multiple growers limping, bowed legs, slow growth | Rickets / Ca:P imbalance | Fix feed, AD3E injection |
| Whole batch 4-8 wk old, lame plus breathing fast plus dying | Glässer's disease | Vet now |
The Six Causes
1. Trauma: slipped, fell, or got pinned
Wet concrete is the number-one cause of "sudden pilay" in PH backyard pens. The pig slips off the feeder ramp, comes up limping on one leg, no fever, still eating. Rest in dry bedding 48 hours. Meloxicam injectable (0.4 mg/kg, ₱250-600 per 50mL vial) is the cleanest pain option; aspirin in feed (10 mg/kg) works in a pinch. If still not weight-bearing by day 3, suspect a fracture: vet or salvage.
2. Foot abscess (pigsa sa kuko)
Hot, swollen, painful at one spot, usually the coronary band or between the claws. Usually follows a puncture from rough flooring or a stone. Pare with a clean blade and pus is normally visible. Drain it, flush with povidone-iodine (Betadine 60mL, ₱170 at any drugstore), then run 3 days of penicillin IM. Robipenstrep (₱460/20mL) at 1 mL per 10 kg covers almost all cases. Drainage alone fixes about half. The drug is insurance.
3. Erysipelas: the one that kills fast
Sudden fever above 40°C, off feed, raised diamond or rectangular red patches, multiple joints stiff. Mostly growers. Untreated, dead in 3 days. With penicillin, recovery is fast, often within 24 hours. Home injection is justified here: the alternative is a dead pig before the vet arrives. See how to inject pigs. Vaccination prevents repeats; ask the agrivet about erysipelas bacterin.
4. Streptococcus suis: zoonotic, watch your hands
Lameness in nursery pigs (3-10 weeks) plus neuro signs: paddling, circling, head tilt, seizures. A 2023 study by Castillo et al. across nine Philippine provinces found S. suis on 15.8% of smallhold farms, almost all serotype 31. The same bug causes meningitis in humans through skin cuts or ingestion. Use gloves. Penicillin or amoxicillin IM works if caught in the first 24 hours; after that, survival drops sharply.
5. Mycoplasma arthritis: the trap
10-30 weeks old, one or two soft swollen joints, hind-leg lameness, NO fever, still eating. Often after transport or pen reshuffling. The trap: it looks bacterial, so farmers reach for Robipenstrep. Penicillin does nothing.
Switch class: tylosin (Tylosin 200, ₱300-500/100mL), lincomycin, or tetracycline. Many cases self-resolve in 7-10 days; pain control speeds it up. If you have already used penicillin and the pig is no better in 48 hours, mycoplasma is your diagnosis until proven otherwise.
6. Rickets: a feed problem, not a drug problem
Multiple pigs in one batch with bowed legs, reluctant to stand, occasional spontaneous fractures. Classic PH cause: a ration heavy in rice bran (darak) with no mineral premix. Phytate in rice bran binds phosphorus, the calcium-phosphorus ratio collapses. Fix the feed first; add a mineral premix or shift to a complete commercial ration for 30 days. Vitamin AD3E (₱350-700/100mL) at 5 mL IM speeds recovery. See pig vitamins and supplements and feed economics.

The Biggest Mistake Backyard Farmers Make
Reaching for Robipenstrep on every lame pig. A 2020 Barroga et al. study found 30% of Philippine backyard farmers buy antibiotics over-the-counter without veterinary advice, and lameness is one of the top reasons. Penicillin is the wrong drug for mycoplasma, trauma, and rickets: three of the six causes above. The pig does not improve, the farmer assumes "the antibiotic failed," and antimicrobial resistance gets one more push. Temperature first. Skin. Feed. Then drug.

Para sa mga mag-uuma
Ang baboy nga pilay, dili kanunay needed ang vet. Tan-awa una. Init ba ang lawas? Tuslokon ang thermometer; kung sobra sa 40.5°C, kuhaa ang Robipenstrep dayon, labi na kung naa pula nga marka sa panit. Kung ang baboy mokaon pa ug walay hilanat, pero pilay sa usa ka tiil tungod sa pag-slip, pahuwaya 48 oras, hatagi ug pain killer (meloxicam), ayaw dayon og injekt og antibiotic.
Ang pinakaduro nga sayop sa daghang mag-uuma: ihatag sa tanang pilay ang penicillin. Dili na mo-trabaho sa mycoplasma, sa nabali, ug sa hina nga buto gikan sa daghan kaayong darak. Tan-awa una unsa ang tinood nga problema, ayha mopalit og tambal.
