| Portable Monitoring Unit (PMU) was located in each houses’ control room for ammonia and carbon dioxide monitoring in layer houses. | Close up of belt layer house air sampling ports with two filters on lines. Cold weather exhaust fan in background behind hen cages. | Each house was fully characterized in relation to dimensions, equipment and management objectives. |

 |
| Inoperative fan opening and tunnel inlet curtains are well-sealed with sheet plastic covered with rigid insulation during winter in cold climate broiler houses. | All the Pennsylvania broiler houses used brooders for supplemental heat. Two houses used a combination of radiant brooders and unit space heaters. | Control room exterior to broiler house environment. Tunnel ventilation inlet curtains closed for winter. |
 |
 |
 |
| Bird level temperature and humidity are recorded during each 48-hour study period. | Broiler houses used box inlets placed along both sidewalls for fresh air entry. | During winter conditions the ammonia Portable Monitoring Unit (PMU) sampled air from in front of the minimum ventilation exhaust fan. |
 |
 |
 |
| Ammonia
emission monitoring was done for 48-hours every three weeks in each
broiler house. |
