Do ammonia emission rates from forced ventilated barns in pig fattening and piglet rearing need to be reviewed?

Abstract: Evaluations of a total of 641 on-site measurements by recognized testing centres in the period from 2020 to 2022 at pig fattening facilities showed an emission rate of at least 3.3 kg/(AP × a) for ammonia – measured with test tubes – with an average animal weight of 77.6 kg (SD = 22.1 kg) and year-round occupancy, even taking into account various measurement uncertainties. The respective monthly mean values for the ammonia concentration in pig fattening varied between 11.5 ppm in August and 15.4 ppm in February and for the barn temperature between 19.0 °C in February and 24.9 °C in July. The monthly average specific air rates varied between 36.5 m³/(AP × h) in January and 78.4 m³/(AP × h) in August. An alternative determination of the NH3 emission rate via the blowdown of properly operated exhaust air purification systems yielded a comparable value of 3.5 kg/(AP × a). Corresponding evaluations of 179 on-site measurements at piglet rearing facilities in the period from 2.... https://www.landtechnik-online.eu/landtechnik/article/view/3303
