各种营养管理策略，减少肠道甲烷（CH 4）的生产进行了讨论。农民最有可能实施的战略包括增加饮食中的谷物含量、添加脂质和补充离子载体（> 24 ppm），因为除了提高生产效率外，它们还很有可能减少CH4排放。改进牧场管理、用玉米青贮饲料取代牧草青贮饲料以及使用豆类，这些措施有望缓解CH4，但其影响尚未得到充分记录。一些新的战略，包括膳食补充皂苷和单宁，选择酵母培养物和使用纤维消化酶可能会减少CH4，但这些仍然需要广泛的研究。大多数关于通过饮食管理减少反刍动物排放的CH4的研究都是短期的，仅侧重于肠道排放的变化。今后的研究必须审查减少甲烷产量的长期可持续性以及对整个农场温室气体预算的影响。
A variety of nutritional management strategies that reduce enteric methane (CH4) production are discussed. Strategies such as increasing the level of grain in the diet, inclusion of lipids and supplementation with ionophores (> 24 ppm) are most likely to be implemented by farmers because there is a high probability that they reduce CH4 emissions in addition to improving production efficiency. Improved pasture management, replacing grass silage with maize silage and using legumes hold some promise for CH4 mitigation but as yet their impact is not sufficiently documented. Several new strategies including dietary supplementation with saponins and tannins, selection of yeast cultures and use of fibre-digesting enzymes may mitigate CH4, but these still require extensive research. Most of the studies on reductions in CH4 from ruminants due to diet management are short-term and focussed only on changes in enteric emissions. Future research must examine long-term sustainability of reductions in CH4 production and impacts on the entire farm greenhouse gas budget.
