Odour and ammonia emissions were measured at four intensive pig units in Ireland. Odour samples were collected on-site and analysed for odour concentration using an olfactometer. Ammonia concentrations in the exhaust ventilation air were measured using a portable sensor. The geomean odour emission rates over the four pig units were 17.2, 44.4, 4.3, 9.9 and 16.8 ou(E) s(-1) animal(-1) for dry sows, farrowing sows, first stage weaners, second stage weaners and finishers, respectively. The mean ammonia emission rates, measured at two of the units, were 12.1, 17.1, 1.4, 2.9 and 10.0 g d(-1) animal(-1) for dry sows, farrowing sows, first stage weaners, second stage weaners and finishers, respectively. In general, the odour and ammonia emission rates were comparable to those reported in literature, although some odour emission rate figures were noticeably lower for finishing pigs in this study. The variability in the data highlights the need for individual site assessment.
在爱尔兰的四个集约化养猪场对气味和氨气排放进行了测量。气味样本在现场采集，并使用嗅觉计分析气味浓度。使用便携式传感器测量排气通风空气中的氨气浓度。四个养猪场的几何平均气味排放率分别为：空怀母猪17.2 ou(E) s(-1) 头(-1)、分娩母猪44.4 ou(E) s(-1) 头(-1)、第一阶段断奶仔猪4.3 ou(E) s(-1) 头(-1)、第二阶段断奶仔猪9.9 ou(E) s(-1) 头(-1)、育肥猪16.8 ou(E) s(-1) 头(-1)。在其中两个猪场测量的平均氨气排放率分别为：空怀母猪12.1 g d(-1) 头(-1)、分娩母猪17.1 g d(-1) 头(-1)、第一阶段断奶仔猪1.4 g d(-1) 头(-1)、第二阶段断奶仔猪2.9 g d(-1) 头(-1)、育肥猪10.0 g d(-1) 头(-1)。总体而言，气味和氨气排放率与文献报道的相当，尽管本研究中育肥猪的一些气味排放率数据明显较低。数据的变异性突出了进行单个场地评估的必要性。
