Poultry Litter Management & Moisture Control Guide
Technical guide covering bedding material selection, target litter moisture (20-25%), ammonia reduction, footpad dermatitis prevention, and litter acidifiers.
Scientific Overview
Proper litter management is the foundation of poultry house air quality, footpad health, and broiler growth performance. Maintaining ideal litter moisture levels (20% to 25%) prevents caking, reduces ammonia (NH3) gas release, and eliminates the root cause of footpad dermatitis and breast blisters.
Bedding Material Selection: Shavings vs Rice Hulls vs Straw
Popular poultry bedding substrate benchmarks:
- Pine Wood Shavings: High moisture absorption capacity, low dust, ideal for brooding. Avoid hardwood shavings containing toxic tannins.
- Rice Hulls: Excellent moisture release and low caking tendency, though slightly lower initial absorbency than pine shavings.
- Chopped Straw: Cheap but prone to rapid caking and mold growth (Aspergillus) if chopped over 2.5 cm long.
Litter Moisture & Ammonia Dynamics
When litter moisture exceeds 30%, microbial breakdown of uric acid into ammonia gas accelerates exponentially. High ammonia (>20 ppm) causes tracheal cilia paralysis, eye ulceration, and reduced feed consumption.
Chemical Litter Acidifiers (PLT, Sodium Bisulfate)
Applying chemical acidifiers (such as Sodium Bisulfate / PLT) to reused or damp litter before chick placement lowers litter pH below 4.0, inhibiting ammonia-producing bacteria during the critical early brooding weeks.
