| An in vitro study was conducted to investigate the effect of different concentrations of Euglena (Euglena gracilis) on CH4 production, dry matter (DM) digestibility, volatile fatty acid (VFA) and ammonia N(NH3-N) concentration as well as on the protozoa population. The treatments considered were Euglena at concentrations of 0.0, 50, 100, 200, 400 and 1000 g/kg dry matter (DM) of the substrate (60:40 forage: concentrate ratio) incubated for 24 and 96 h using an in vitro continuous gas production and in vitro two-stage digestion procedure, respectively. The data were subjected to polynomial regression analysis. Methane emissions (ml/g DM) decreased at an increasing rate, generally with increasing concentration of Euglena but also exhibited quadratic (P<... |

| Sunphenon 30S-O is obtained from the leaves of traceable green tea (Camellia sinensis) and standardized for its catechin content (205 g/kg DM). This experiment was conducted to evaluate the effect of supplementation with different concentrations of Sunphenon 30S-O on methane emissions, nutrient intake, digestibility, protozoa abundance and the concentrations of volatile fatty acids (VFA) and ammonia-N (NH3-N) in sheep. Four Corriedale wethers with an average body weight of 64.25 +/- 3.86 kg were arranged in a 4 x 4 Latin square and fed a basal diet of Guinea grass (Panicum maximum) hay at the maintenance level with four different concentrations of Sunphenon 30S-O (0, 10, 25 and 40 g/Kg DM intake). The experiment was conducted over 84 days in four 21-day... |

| 本研究では，貯留中の乳牛ふん尿スラリーから発生する環境負荷ガスを低減するため，化学肥料を撥水加工した革新的なカバー資材を開発し，その抑制効果の評価とメカニズムについて検証した。スラリーは，メタン発酵前と発酵後の2種類を用いた。資材は，スラリー上に浮かべることを可能とし，また農地還元する上で不足する植物養分を補給するために，微粉砕した化学肥料に疎水性シリカを混合することにより調製した。実験室規模で13日間のガス発生量を測定した。アンモニアやメタンの積算発生量はメタン発酵後のスラリーの方が発酵前のそれよりも高かった。本資材を供試することにより，スラリーから発生するガスの吸着またはスラリーの発酵挙動が変化し，アンモニアやメタンの発生量が著しく減少した。さらに，資材の一部が溶解してスラリーの養分量が増加するので，本技術は農作業の効率化が図られるとともに，畜産廃棄物の有効利用に役立つと考えられる。 The objectives of this study were to verify the effectiveness in reducing polluting gas emissions of novel methods for covering dairy slurry by using various types of hydrophobic fertilizers and to evaluate the mechanisms for reducing gas emissions from this slurry before and after methane fermentation. The hydrophobic fertilizers were prepared by mixing... |
