Animal Industry Report
Extension Number
ASL R2802
Topic
Poultry
Summary and Implications
Ammonia (NH3) concentrations and emissions were monitored in four aviary laying-hen houses for one year. The mean indoor NH3 concentration of the four houses (mean ± SE) was 5.2 (±0.1) ppm. The NH3 concentrationswere below 25 ppm, the commonly recommended threshold, on all sampling days. Ammonia emission rate was 0.14(±0.01) g/d-hen. The NH3 concentrations and emission rateof the aviary houses were between those of manure-belt and high-rise cage houses reported in the literature.
