Özet

The objective of this study was to determine magnitude of ammonia emissions from dairy cattle freestall barns with natural ventilation. The measurements of ammonia concentration and indoor environmental conditions in barns were done throughout the 4 days in three dairy farms in summer season. The overall hourly average temperature and relative humidity for all barns were 26.5 degrees C and 61%, respectively. In monitored dairy cattle barns, ammonia concentrations were observed between 0.4 and 8.77 ppm. The overall hourly average ammonia emission was calculated as 56.1 g/h.barn. Ammonia concentrations in. creased with lower airflow rate while ammonia emissions increased with higher airflow rate. As a result of this study, there is no significant relationship observed between ammonia emission and indoor environmental conditions such as temperature and relative humidity.
