フェヌグリーク種子粕（FSM）を大豆粕の代替としてルーメン発酵と温室効果ガス産生に及ぼす影響をin vitroで評価。25%代替でメタンや二酸化炭素の産生が変化し、発酵性が向上するが、高配合では繊維分解が低下。畜産分野のGHG削減に寄与する可能性を示唆。
English
This study evaluates fenugreek seed meal (FSM) as a partial replacement for soybean meal in ruminant diets, examining effects on in vitro rumen fermentation and greenhouse gas emissions. At 25% replacement, gas production and metabolizable energy increased, while higher inclusion reduced fiber degradability. Findings suggest FSM could mitigate livestock GHG emissions, though in vivo validation is needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の畜産分野では、輸入飼料への依存低減とGHG排出削減が課題。FSMのような国産代替タンパク源の活用は、持続可能な畜産経営に寄与する可能性があり、GX関連の政策や補助金の対象となり得る。
In the global GX context
Globally, livestock contributes ~14.5% of anthropogenic GHG emissions. Alternative feed ingredients like FSM can reduce reliance on soybean meal (often linked to deforestation) and lower enteric methane, aligning with climate goals and sustainable agriculture targets.

📄 Abstract（原文）
Abstract The use of alternative protein sources in ruminant diets has the potential to reduce feed costs and mitigate environmental impacts associated with conventional protein feeds. This study evaluated the effects of partially or completely replacing soybean meal (SBM) with graded levels of fenugreek seed meal (FSM; 0, 4.3, 8.6, 12.9, and 17.3% of DM) on in vitro ruminal fermentation, gas production, methane (CH 4 ) and carbon dioxide (CO 2 ) emissions, and nutrient degradability. FSM contained lower concentrations of essential amino acids (74.3 g/kg DM) than SBM (157 g/kg DM), whereas total polyphenols were higher in FSM (2014.9 µg/g) than SBM (1453.3 µg/g), particularly catechin, ellagic acid, methyl gallate, and rutin. Ruminal gas production kinetics were altered. The asymptotic gas volume ( b ) increased with 25% FSM inclusion (323.9 mL/g DM) relative to the control (300.7 mL/g DM; P = 0.005), but decreased at higher inclusion levels, with a significant quadratic effect ( P = 0.014). The fractional gas production rate ( c ) and lag time were also affected ( P ≤ 0.03), as was metabolizable energy, which peaked at FSM25 ( P = 0.007). In vitro dry matter degradability and fiber degradation decreased linearly and quadratically at higher FSM levels ( P < 0.05). Total volatile fatty acids, acetate, and propionate concentrations were higher at FSM25 compared to FSM0 but declined at greater FSM inclusion ( P ≤ 0.037). Ruminal pH increased with higher FSM levels ( P = 0.007). These results indicate that partial replacement of SBM with FSM (approximately 25% of SBM protein) can enhance ruminal fermentation and metabolizable energy, whereas higher inclusion rates reduce fiber degradability and alter fermentation end-products.
