🦆 Duck Respiratory Diseases in 2025: A Vet’s Guide by Dr Duncan Houston BVSc 💨

By Dr Duncan Houston BVSc – Respiratory illness in ducks ranges from common bacterial infections to deadly viral diseases like duck plague. In this thorough 2025 guide, we'll walk through major conditions—symptoms, diagnostic protocols, treatments, housing strategies, and modern innovations to protect your flock's breathing health. Let’s ensure your ducks quack strong and breathe easy! 🌿

📘 Overview of Common Duck Respiratory Conditions

• Duck Plague (Duck Viral Enteritis) – a herpesvirus causing nasal discharge, coughing, green diarrhea, and high mortality :contentReference[oaicite:3]{index=3}.
• Airsacculitis – bacterial or fungal infection of respiratory air sacs, causing neck swelling, cough, labored breathing :contentReference[oaicite:4]{index=4}.
• Bacterial/Pneumonic Infections – due to pathogens like Pasteurella, E. coli, or Mycoplasma, manifesting as sneezing, nasal/eye discharge, and pneumonia symptoms :contentReference[oaicite:5]{index=5}.

⚠️ Causes and Risk Factors

• **Viral agents:** Duck plague virus (Anatid alphaherpesvirus 1) :contentReference[oaicite:6]{index=6}.
• **Bacterial/fungal agents:** E. coli, Mycoplasma, Bordetella, Pasteurella, Aspergillus :contentReference[oaicite:7]{index=7}.
• Poor ventilation, high humidity, dusty bedding, overcrowding—major environmental risks :contentReference[oaicite:8]{index=8}.
• Stressors like cold, mixing flocks, transport.
• Wild migratory birds introduce pathogens, especially plague virus.

👀 Watching for Clinical Signs

• **Sneezing, coughing, wheezing, labored breathing.**
• **Discharges:** nasal, ocular—can be clear, mucous, or blood-tinged.
• **Swelling:** neck or throat due to infected air sacs (airsacculitis) :contentReference[oaicite:9]{index=9}.
• **Lethargy, reduced appetite, weight loss**.
• **Duck plague-specific:** sudden green diarrhea, high mortality in flock :contentReference[oaicite:10]{index=10}.

🔍 Diagnostic Approach

• Physical exam: auscultation for crackles/wheezes, palpation of neck.
• Swabs: nasal/throat air sac cultures for bacteria/fungi.
• Imaging: endoscopy or ultrasound of air sacs; X-rays for pneumonia.
• Lab work: CBC, biochemistry for systemic infection.
• Viral testing: PCR or serology for duck plague.

💊 Treatment Protocols in 2025

1. Duck Plague Management

• No cure—supportive care only. Infected flocks often require culling.
• Vaccination with attenuated vaccines is essential :contentReference[oaicite:11]{index=11}.
• Strict biosecurity: separate from wild birds, disinfect water sources.

2. Airsacculitis Treatment

• Surgical drainage under anesthesia when abscesses present.
• Long-term antibiotics based on culture (e.g., enrofloxacin).
• Support with anti-inflammatories (meloxicam), humidification.

3. Bacterial Pneumonia Therapy

• Targeted antibiotics (e.g., doxycycline, trimethoprim‑sulfa).
• Hospitalize: provide warmth, hydration, oral fluids.
• Nebulization or steam therapy to alleviate respiratory distress.

🏠 Housing & Environmental Support

• Ventilate well—avoid dry, dusty bedding. Use straw or pelleted wood.
• Maintain moderate humidity; avoid overcrowding.
• Offer clean, flowing water away from airborne contaminants.
• Isolate sick individuals to stop spread.
