This study was conducted in three similar-structured pig rooms for approximately 160 days from March 25 to August 31, 2021 to investigate greenhouse gas emissions and characteristics emitted from sow housing with forced ventilation systems. Greenhouse gas emissions and coefficients were calculated by real-time measurement of greenhouse gas (Nitrous Oxide, Methane) concentrations, ventilation rate, and inside temperature and humidity in a pig house based on the mega chamber method, which assumes a closed pig room in the form of a chamber. The average concentration of Nitrous Oxide (N₂O) in each room was in the range of 0.5 to 0.6 ppm, and Methane (CH₄) concentration was in the range of 28.9 to 33.5 ppm. The average N₂O emissions from Rooms 1 to 3 were 4.7 ± 1.4, 4.5 ± 1.3, and 5.2 ± 1.6 mg/day·m²·pig. In the case of CH₄, average emissions were 86.0 ± 15.6, 100.2 ± 31.2, and 103.3 ± 26.7 mg/day·m² ·pig. Finally, greenhouse gas emissions from sows calculated in this study were 1.87 ± 0.6 g/year·m²·pig (N₂O) and 35.4 ± 8.8 g/year·m²·pig (CH₄). Greenhouse gas emission coefficients were calculated as carbon dioxide equivalent (CO<SUB>2-eq</SUB>) by applying Global Warming Potential (GWP) and were 1.38 g CO<SUB>2-eq</SUB> and 2.64 g CO<SUB>2-eq</SUB> for N₂O and CH₄, respectively. This suggests that the contribution of CH₄ is higher than that of N₂O emitted by sows. The results of this study present useful data for domestic emission coefficient research.
