Excessive Ammonia Build-Up And Poor Ventilation



Ammonia gas (NH₃) accumulates when uric acid decomposes under high moisture and microbial activity.

Ammonia levels above 25 ppm reduce tracheal epithelial efficiency and increase disease susceptibility.

Mechanical ventilation must be calibrated based on bird weight and environmental humidity.

Frequently Asked Questions



Q1: What are the main factors causing ammonia accumulation in deep litter systems?

A1: Ammonia accumulation occurs due to microbial decomposition of uric acid in wet litter, insufficient ventilation, and high stocking density, which together increase respiratory stress and reduce feed efficiency.

Q2: How can coccidiosis outbreaks be minimized in floor-based poultry houses?

A2: Coccidiosis prevention requires maintaining dry litter, controlling temperature and relative humidity within optimal ranges, and applying anticoccidial interventions to break the parasite life cycle.

Q3: Which bedding materials optimize bird welfare and production efficiency?

A3: Softwood shavings and fine sawdust improve moisture absorption, reduce litter caking, limit ammonia release, and decrease footpad dermatitis incidence, thereby supporting higher egg production and growth rates.
