In Annex 1 countries, nitrous oxide ( N 2 O ) emissions from swine and poultry excreta have been calculated and the N 2 O reduction potential of each country by using amino acids in feed could also be calculated, then a comparison made among the countries. The N 2 O reduction rates were approximately 25% for these Annex 1 countries and amino acids were able to make a large contribution to that reduction. Greenhouse gases ( GHG ) which are N 2 O combined with methane ( CH 4 ) were estimated to reduce by 24.8% in J apan when amino acids were introduced into the feed, but only a 7.2% reduction was estimated in F rance. Purification, which is mainly used for manure treatment in J apan, emits much more N 2 O and less CH 4 , whereas the liquid system which is mainly used in F rance emits more CH 4 and less N 2 O based on the emission factors from the United Nations Framework Convention on Climate Change data base. Changing the F rench manure treatment system to the Japanese style with amino acids in feed would reduce GHG emissions by 23.4%. Reduction of the arable land use in J apan by changing crop formulations supported by adding amino acids to feed was also quantified as about 10% and led to an increase in the production of meat using the same arable land area.
