Newcastle Disease (NCD): Causes, Symptoms, and What to Do
Newcastle Disease has no cure and can wipe out an entire flock. Learn the symptoms, how to manage it, and why vaccination is the only prevention.
What Is Newcastle Disease?
Newcastle Disease (NCD) is caused by the Newcastle Disease Virus (paramyxovirus). It is the most feared disease in poultry in the Philippines — there is no cure, and it can kill up to 100% of your flock if not managed immediately.
There is no cure for NCD. The only way to protect your birds is vaccination.
Symptoms
- Sudden death — can wipe out an entire flock
- Coughing, sneezing, difficulty breathing (gasping)
- Greenish, watery diarrhea
- Drooping wings
- Twisted neck, paralysis — this is the classic sign of NCD in its advanced stage
- Swollen eyes, nasal discharge
- Complete cessation of egg production
Important: If you see a bird with a twisted neck and paralysis, it's most likely NCD. Act immediately.
How to Manage (No Cure)
| Action | What to Do |
|---|---|
| If NCD is suspected | Isolate affected birds immediately — separate them from the rest of the flock |
| Medication | Premoxil (10g/gallon, 5–7 days) to prevent secondary bacterial infections ONLY — this does not treat NCD itself |
| Support | Vitmin Pro daily (10g/gallon) for immune support |
| Reality | Severely affected birds will likely die. Focus your efforts on protecting the rest of the flock. |
The Most Important Thing
| Prevention | Vaccination is the ONLY prevention — confirm with your breeder which NCD vaccines were administered |
NCD Vaccination Schedule
If you're raising chicks from hatch, follow the standard NCD vaccination schedule:
| Day | Vaccine | Method |
|---|---|---|
| Day 3 | Newcastle B1 | Nasal drop |
| Day 7 | Newcastle B1 La Sota | Nasal drop |
| Day 74 | Newcastle B1 La Sota Booster | Nasal drop |
If you purchased birds: Ask the breeder if NCD vaccination is complete. If unsure, revaccinate to be safe.
Note: The vaccination schedule may vary depending on your area and veterinarian. The schedule above is a common protocol in Philippine gamefowl practice. Consult your vet for a schedule suited to your situation.
Prevention
- Vaccination, vaccination, vaccination — there is no other way
- Isolate newly arrived birds for at least 2 weeks
- Don't bring your birds to areas with other poultry if they're not vaccinated
- If there's an outbreak in your area, don't allow anything in or out of your farm (biosecurity lockdown)
Golden Rules of Treatment
- Don't mix Sulpar QR and Premoxil in the same water. Sulpar QR in the morning, Premoxil in the afternoon — keep them separate.
- Don't mix medication with Vitmin Pro on the same day during treatment. Give Vitmin Pro only during the recovery phase (after the treatment protocol).
- Always use freshly prepared medicated water every day. Never reuse yesterday's mix.
- Remove all other water sources during treatment to ensure the birds drink the medicated water.
- Isolate sick birds immediately from the healthy flock — don't wait.
- Complete the full treatment course even if the bird looks fine by Day 2. Stopping early risks creating drug-resistant bacteria.
- Prevention is better than treatment. Clean coop, dry sand, regular deworming, and proper vaccination.
