Abstract: This paper provides an overview of the regional distribution characteristics of Jiangxi scale pig farming and pig breeding stock, and also summaries the trends of 2004-2011. The pig breeding enteric methane emissions and methane and nitrous oxide emissions from manure handling mechanisms were introduced, the various regions at different times of the greenhouse gas emissions of pig breeding were calculated, and the greenhouse gas emissions affecting factors of pig breeding were analyzed. Combined with the situation of Jiangxi province, the suggestions on pig breeding greenhouse gas emissions were proposed.
