Ammonia, nitrous oxide, methane, carbon dioxide and water vapour emissions in a fattening pig house on deep litter: levels of production and correlation with pigs activity. [French]

摘要

During a 4-month fattening period, emissions of NH3, N2O, CH4, CO2 and H2O from a pig house with fattening pigs on deep litter was measured once a month during four days (one measurement every 30 min). The activity rate of the animals was also measured hourly as the mean proportion of standing animals observed each two minutes.
