Interest in greenhouse gas (GHG) emissions from animal feeding operations is increasing. However, information is meager concerning GHG emissions from swine operations, particularly from breeding, gestation, and farrowing facilities. The purpose of this study is to quantify GHG emissions from a breeding/gestation and farrowing facility located in Central Iowa. The monitored portion of the facility consists of a deep-pit breeding barn (1800 head), a deep-pit gestation barn (1800 head), and two shallow-pit farrowing rooms (40 farrowing crates per room). Monitoring began in January 2011 and will continue for one year to cover the seasonal effects on the emissions. This paper reports on data collected from January 12, 2011 to May 31, 2011. A mobile air emissions monitoring unit is dedicated to the extensive monitoring. At the time of this writing, results from the study show the following average daily emissions per animal unit (AU = 500 kg body mass): 31.9 g NH3, 8.82 kg CO2, 0.1 g N2O, and 283.1 g CH4 for sows in the breeding/early gestation barn; and 32.8 g NH3, 9.77 kg CO2, 0.1 g N2O, and 290.1 g CH4 for sows in the late gestation barn. For the farrowing rooms, results to date show the following average cumulative emissions per crate (sow and piglets): 1.02 kg NH3, 308 kg CO2, 0.0038 kg N2O, and 1.53 kg CH4. The 6 turns through each room had an average lactation period of 22 days, litter size of 10.5 piglets, and weaned piglet body weight of 5.59 kg.
