Special Issue Information
Methane production from ruminants has been a major concern worldwide due to its impact on climate change through contributing to global warming. Ruminant methane production constitutes 17% of the anthropogenic sources of global atmospheric methane, and that is 28-fold the global warming potential of carbon dioxide. Decreasing the production of enteric methane from ruminants is a strategy in reducing greenhouse gas emission and improving nutrition such as feed conversion efficiency. One of the strategies in reducing methane production is through metabolic pathways involved in H2 production and utilization. This strategy shifts to alternative H2 metabolizing microorganisms, which stimulate beneficial rumen microbial populations rather than those that use methanogenesis. The use of functional microbes that compete with methanogens is a promising strategy in decreasing methane emission. This diverts methanogenesis by shifting the fermentation pathways to produce metabolites that are used by the animal as source of energy and essential in improving ruminant performance.
Rumen functional microbes are microorganisms in the rumen that are used to reduce methane production by shifting the fermentation to pathways other than methanogenesis and increasing the productivity of ruminants. There are several ways to shift the fermentation pathways and this is through rumen biochemical pathways. In the rumen biochemical pathways, the methane production could be modulated and/or decreased through the use of functional rumen microbes. These are through homoacetogenesis, fumarate and propionate production, sulphate and nitrate/nitrite reduction, capnophily, and methane oxidation.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
