Ruminal ciliates are a fundamental constituent within the rumen microbiome of ruminant animals. The complex interactions between ruminal ciliates and other microbial guilds within the rumen ecosystems are of paramount importance for facilitating the digestion and fermentation processes of ingested feed components. This review underscores the significance of ruminal ciliates by exploring their impact on key factors, such as methane production, nitrogen utilization efficiency, feed efficiency, and other animal performance measurements. Various methods are employed in the study of ruminal ciliates including culture techniques and molecular approaches. This review highlights the pressing need for further investigations to discern the distinct roles of various ciliate species, particularly relating to methane mitigation and the enhancement of nitrogen utilization efficiency. The promotion of establishing robust reference databases tailored specifically to ruminal ciliates is encouraged, alongside the utilization of genomics and transcriptomics that can highlight their functional contributions to the rumen microbiome. Collectively, the progressive advancement in knowledge concerning ruminal ciliates and their inherent biological significance will be helpful in the pursuit of optimizing rumen functionality and refining animal production outcomes.
瘤胃纤毛虫是反刍动物瘤胃微生物群的基本组成部分。瘤胃纤毛虫与瘤胃生态系统中其他微生物群落之间的复杂相互作用对于促进摄入饲料成分的消化和发酵过程至关重要。本综述通过探讨瘤胃纤毛虫对甲烷产生、氮利用效率、饲料效率和其他动物生产性能指标等关键因素的影响，强调了瘤胃纤毛虫的重要性。在瘤胃纤毛虫的研究中采用了多种方法，包括培养技术和分子方法。本综述强调迫切需要进一步研究，以辨别各种纤毛虫物种的不同作用，特别是与甲烷减排和提高氮利用效率相关的作用。鼓励推动建立专门针对瘤胃纤毛虫的强大参考数据库，同时利用基因组学和转录组学，以突出它们对瘤胃微生物群的功能贡献。总体而言，关于瘤胃纤毛虫及其内在生物学意义的知识的逐步进步，将有助于优化瘤胃功能和改善动物生产结果。
