*Reducing Ammonia Formation in Poultry Litter

Smart Practices for Healthy Birds & Better Production**

                Ammonia (NH₃) is one of the biggest invisible enemies inside poultry houses. It forms when uric acid from droppings breaks down due to moisture and microbial action. If not controlled, ammonia harms bird health, reduces growth and feed efficiency, and even affects workers’ health.

            Let’s explore simple, practical ways to reduce ammonia formation in poultry litter—beneficial for farmers, students, and poultry professionals.

🔹 Why Ammonia is a Problem?

When ammonia levels rise:

✔ Birds eat less and grow slowly
✔ Respiratory infections and eye irritation increase
✔ Mortality risk rises
✔ Feed conversion efficiency becomes poor
✔ Egg producers face lower production
✔ Bedding/litter becomes wet and unhygienic

Ideal ammonia level: Below 20 ppm

✔ 1. Maintain Dry Litter

Moisture is the primary driver of ammonia formation.

Best Practices

✔ Use good absorbent litter (rice husk, wood shavings)
✔ Ideal litter moisture: 20–25%
✔ Stir/turn litter weekly
✔ Remove caked/wet areas around drinkers

✔ 2. Proper Ventilation and Air Circulation

Fresh air reduces moisture and ammonia buildup.

Tips:

✔ Install exhaust fans / side curtains
✔ Maintain airflow over litter
✔ Avoid overstocking (density 8–10 birds/sq. ft. for broilers)

✔ 3. Control Water Spillage

Wet litter = more ammonia.

✔ Use nipple drinkers instead of bell drinkers
✔ Maintain correct drinker height
✔ Regularly check for leaks

✔ 4. Use Litter Treatment Chemicals or Amendments

Some products reduce litter pH and control ammonia release.

Common options:

🔸 Alum (Aluminium sulphate)
🔸 Superphosphate / Gypsum
🔸 Sodium bisulfate
🔸 Zeolite or clay minerals

These reduce ammonia by binding nitrogen or lowering pH.

✔ 5. Good Nutrition Practices

Proper feed formulation directly affects waste quality.

✔ Balanced protein levels
✔ Use enzymes like phytase, protease
✔ Feed additives (Yucca products) help reduce ammonia in feces

✔ 6. Keep Birds Comfortable

Stress-free birds produce drier droppings.

✔ Maintain correct brooding temperature
✔ Avoid overcrowding
✔ Provide sufficient feeder & drinker space

✔ 7. Litter Management Between Batches

After flock removal:

✔ Windrow composting or tilling
✔ Add fresh litter or top dress
✔ Full litter removal periodically

✔ 8. Biosecurity and Disease Control

Diarrhea due to infections increases wet litter.

✔ Vaccination
✔ Regular health monitoring
✔ Deworming
✔ Quick treatment of enteric diseases

Benefits of Reducing Ammonia Levels

🐥 Better bird health
🥚 More egg production
💪 Improved body weight gain
🧪 Reduced medication cost
👨‍🌾 More profits for farmers
🌿 Better environment for workers

Conclusion

Ammonia control is not a single-step action—
it is a combination of good housing, nutrition, litter management and ventilation practices.

By keeping litter dry, reducing moisture, and using natural or chemical additives, farmers can create a healthier house environment that supports bird growth and profitability.

Cleaner litter = Healthier flock = Higher earnings!
