摘要
Mitigating methane losses from cattle has economic as well as environmental benefits. The aim of this paper is to review the current approaches in relation to associated advantages and disadvantages and future options to reduce enteric methane emission from cattle. Current technologies can be broadly grouped into those that increase productivity of the animal (improved nutrition strategies) so that less methane is produced per unit of meat or milk, and those that directly modify the rumen fermentation so that less methane is produced in total. Data suggest that many of these practices are not appropriate for long term mitigation of methane emissions in ruminants because of their constraints. So it is necessity to develop long term strategies in suppressing methane production. An integrated research investigating animal, plant, microbe and nutrient level strategies would offer a long term solution of methane production. Genetic selection of animals, vaccination, probiotics, prebiotics and plant improvement are the most promising options of all the future approaches discussed. These approaches will reduce enteric methane production without any hazard to animal or environment.

从牛的缓解甲烷损失具有经济和环境效益。本文的目的是检讨现行的方法相对于相关的优势和劣势，未来的选择，以减少肠道牛的甲烷排放。当前的技术大致可分为那些增加动物的生产力（改善营养的策略），以使较少的甲烷被每单位生产的肉或牛奶，和那些直接修改瘤胃发酵，使得较少的甲烷产生总共。数据表明，许多这些做法是不适合的甲烷排放量的长期缓解，因为它们的约束的反刍动物。所以它是必要制定长期战略，在抑制甲烷的生产。一个集成的研究调查的动物，植物，微生物和营养水平的战略将提供沼气生产的长期解决方案。遗传选择的动物，接种疫苗，微生态制剂，益生元和植物改良是所有讨论未来的方式最有前途的选项。这些方法会减少肠道产甲烷没有任何危害的动物或环境中。
