Fowl Typhoid and Pullorum: Causes, Symptoms, and Treatment
Learn the difference between typhoid and pullorum, the telltale white chalky droppings, and the treatment protocol using Sulpar QR and Premoxil.
What are Fowl Typhoid and Pullorum?
These are two different diseases, both caused by Salmonella bacteria:
- Fowl Typhoid — caused by Salmonella gallinarum, more common in adult birds
- Pullorum — caused by Salmonella pullorum, more common in chicks
Both are dangerous and can be fatal — especially in young birds.
Symptoms
- White or chalky diarrhea — especially in young birds, this is the most telltale sign
- Pasting of vent — droppings stuck around the vent area
- Huddling near heat sources
- Loss of appetite, weakness
- Sudden death in chicks
- Decreased egg production in adults
In chicks: If you see white paste stuck to the vents of chicks and they start dying, suspect pullorum immediately.
Treatment Protocol: Sulpar QR + Premoxil (6 Days)
| Day | Morning | Afternoon |
|---|---|---|
| Day 1–3 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
| Day 4 | Plain water only (REST DAY) | Plain water only (REST DAY) |
| Day 5–6 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
Sulpar QR is effective against fowl typhoid (Salmonella gallinarum). Premoxil is effective against pullorum and other bacterial infections sensitive to Amoxicillin and Tylosin.
Recovery Phase
| Day | Medication |
|---|---|
| Day 7–9 | Vitmin Pro — 10g per gallon of water, daily |
Prevention
- Buy chicks only from clean and reputable breeders — do not buy from just anywhere
- Keep the coop dry and clean
- Carriers can appear healthy — always isolate new stock before introducing them to the flock
- Disinfect waterers and feeders regularly
Golden Rules for Treatment
- Never mix Sulpar QR and Premoxil in the same water. Sulpar QR in the morning, Premoxil in the afternoon — keep them separate.
- Do not 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 each day. Do not 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 — do not wait.
- Complete the entire treatment course even if the bird looks fine by Day 2. Stopping early risks creating drug-resistant bacteria.
- Prevention is better than treatment. Keep the coop clean, sand dry, deworm regularly, and vaccinate properly.
