Problem:
Mechanism: In the rumen, methane is mainly produced when microbes ferment fiber to acetate and hydrogen, which methanogens convert to CH4. Higher-protein, higher-quality diets typically: Increase digestibility and shift fermentation toward propionate, which uses hydrogen and leaves less for methanogens. Improve feed efficiency so less feed is required per unit of product, cutting total emissions intensity. Often replace highly fibrous feeds with legumes or concentrates that reduce methanogenesis. Application: Formulate rations with adequate rumen-degradable and bypass protein (e.g., high-quality forages, legumes, oilseed meals), balance energy-to-protein ratio, and monitor milk/meat yield to ensure productivity gains. Pair with known CH4-mitigating additives (e.g., fats, tannins, 3-NOP where allowed) for additional reductions. Result: lower methane per animal and per unit of product. summarize in a small paragraph. Need Assignment Help?
