Rumen Microbiome-Challenges and opportunities to manipulate and improve its function
Ruminants depend on the symbiotic ruminal microbiome for their living and productivity.The ruminal microbiome is a complex community of microorganisms that include bacteria of different guilds, archaea of mostly methanogens, ciliate protozoa, fungi, and viruses of mostly phages of bacteria and archaea (Hobson and Stewart, 1997).It is this ruminal microbiome that drives the digestion of indigestible feed ingredients,especially fiber, to energy and nutrients that ruminant animals can assimilate.It is also because of this ruminal microbiome that ruminants became and continued to be the most populous and competitive herbivores on the Earth.The rumen microbiome has a high density of microorganisms, with the bacteria alone reaching up to 1011 bacteria per milliliter of rumen content while other forms of ruminal microbes being much less abundance due to low metabolic versatility.Thanks to the traditional microbiological research in the past two hundred years, a large number of the members of the ruminal microbiome have been isolated and cultured, and their basic metabolism, physiology, and ecology are understood.
