Reducing ambiant temperature to lower NH3, N2O and CH4 emissions from pig fattening housing

France is committed to reducing its emission of ammonia by 13% by 2030 compared to 2005 and its emissions of Green House Gases by 40% by 2030 compared to 1990. Temperature is a main factor influencing gaseous emissions in piggeries. A project titled Temporalis, led by Ifip in collaboration with Inrae and the Brittany Agriculture Chamber has been developed to study the influence of cold temperature on fattening performance and gaseous emissions. This poster shows a part of the results obtained in the first part of this project and is focused on the reduction on ambient temperature. A second part is at the moment in progress on the manure cooling.
