 note = {Recently, great concern has gathered in generating from the livestock farm of environmental load gases, such as ammonia (NH₃), nitrous oxide (N₂0) and methane (CH₄). In order to calculate the total amount of each gas per capita which occurs from swine waste, three processes considered to be the main generation sources of each gas was examined. According to the results of those experimental studies, 1）The NH₃(NH₃-N), N₂0(N₂0-N) and CH₄ emissions from pig units during a full fattening period of 8 weeks were estimated at 149, 5.8 and 302g/head respectively. 2）The NH₃ (NH₃-N), N₂0 (N₂0-N)and CH₄ emissions from swine wastewater purification were estimated at negligible, l.8～7.4g and 10.7～37.5g/head respectively. 3) The NH₃ (NH₃-N）, N₂0 (N₂0-N) and CH₄ emissions from compost were estimated at 133～325g, 0.2～129g and 0.7～6.4g/head respectively. 4) The NH₃-N, N₂0-N and CH₄ emissions from the swine keeping unit and its manure contributes (a full fattening period of 8 weeks) were estimated at 271～438, 16.5～49.4 and 270～438g/head respectively. And, 5) Those emission could be reduced by adequate manure contributes, such as ; weekly discharge of slurry in swine unit, employment of intermittent aeration process for wastewater treatment and keeping of aerobic condition during swine manure composting., 標準的な養豚経営の単位家畜あたりのふん尿由来の環境負荷ガス発生総量を算定し，その抑制条件を検討した。肥育全期間中(8週間，20kg～80kgの増体期間)に畜舎内でアンモニア（NH₃)，亜酸化窒素(N₂0) およびメタン（CH₄）が先生する量は，それぞれ181，9.1および302g/頭と試算された。豚ふん尿汚水浄化処理からの放出推定値として，NH₃については検出限界以下、CH₄については1.8～7.4g CH₄/頭，N₂0については10.7-37.5g N₂0-N/頭の発生が試算された。堆肥化過程からの放出推定値として発生はNH₃が133～ 325gNH₃-N／頭，CH₄が0.2～129gCH₄/頭およびN₂0が0.7～6.4gN₂0-N/頭と試算された。発生抑制には，NH₃については肥育豚舎からの放出抑制と堆肥化過程からの物理的捕集，N₂0については間欠曝気法の適用，CH₄については堆肥化を好気的条件で行うことが有効と考えられた。},
