0,0077 tCO2/con/tháng. , Tóm tắt tiếng anh, Applying the methodology of the Intergovernmental Panel on Climate Change (IPCC) in calculating the greenhouse gas emission from pig farming operations at Lam Dong province in 2015, calculated results show that the application of swine manure management solutions can significantly reduce emissions of greenhouse gases into the environment. Using of energy in pig farming operations around 0.0007 tCO2 emissions/ head/ month, the digestion of pig feed create a greenhouse gas emission at around 152.96 tCO2/month with emission factor of 0.0029 tCO2/head / month. Greenhouse gases emitted from the current manure management system (manure are treated by various forms and the rest will directly disposed into the environment) into the atmosphere is around 400.08tCO2/month, respectively a pig emitted about 0.0076 tCO2/head/month. The total emission factor during pig production under the scenarios (1) manure are directly discharged into the environment, (2) manure are managed by current management system, (3) manure are managed by current management systems with the gas generated from biogas recovery is converted into electrical energy and (4) manure are managed by Biogas recovery system, respectively 0.0593
