🔬 Section 2: Diagnosis – What Your Vet Will Do

Essential Tests for Digestive Issues

Case Study: A cockatiel’s "normal" bloodwork delayed PDD diagnosis by 8 months.

💊 Section 3: Treatment Protocols

Medications & Dosages

• Antifungals (Candidiasis): Nystatin (100,000 IU/kg)

• Antibiotics (Bacterial): Enrofloxacin (15 mg/kg)

• Pain Control: Meloxicam (0.5 mg/kg)

⚠️ Warning: Never use over-the-counter bird antibiotics without testing.

Supportive Care at Home

• Critical Care Formula: EmerAid IC Carnivore

• Hydration: Subcutaneous fluids if not drinking

• Heat: 85-90°F hospital cage

🥗 Section 4: Prevention Through Nutrition

Best/Worst Foods for Digestive Health

✅ Good:

• Dark leafy greens (kale, dandelion)

• Soaked pellets (Harrison’s)

• Probiotics (Benebac Plus)

❌ Avoid:

• Avocado (cardiotoxic)

• Dairy (birds are lactose-intolerant)

• Raw beans (phytohemagglutinin poisoning)

Feeding Schedule:

• Small meals 3x/day (mimics natural foraging)

• Fasting periods prevent crop stasis

🚨 Section 5: Emergency Red Flags

Go to the ER IMMEDIATELY if:
🔴 Blood in droppings
🔴 Swollen crop that feels like dough
🔴 Unable to perch (weakness)

First Aid Kit Must-Haves:

• Digital gram scale (track weight daily)

• Heating pad (K&H Snuggle Up)

• Oral syringes (for fluids)

📢 Conclusion: Early Action Saves Lives

Birds hide illness until they’re critically sick. Daily droppings checks + weight monitoring are essential.
