This will help us to understand how the use of feed additives and/or plant secondary metabolites in ruminant diets may be an interesting feeding strategy to modify the rumen function of animals by altering nutrient digestion pathways, changing the ruminal fermentation process, inhibiting methanogenesis, modulating microbial populations, adjusting the biohydrogenation of fatty acids, and reducing the risk of metabolic diseases, thus improving ruminant productivity and health.

Ruminal Microbiota, Fermentation Process, Enteric Methane Emissions, and Animal Performance. Special Issue Reprint Ruminants. MDPI AG. Switzerland. NO This Special Issue, entitled “Ruminal Microbiota, Fermentation Process, Enteric Methane Emissions, and Animal Performance”, ranges in scope from animal nutrition to animal production, including ruminal fermentation and its environmental influence on greenhouse gas emissions. The aim of this collection is to cover recent research findings relating to livestock microbiota, their role in digestion, and their impact on enteric methane emissions in ruminants. The purpose of this Special Issue is to contribute to scientific knowledge on the use of feed additives, by-products, or plant secondary metabolites for animal feeding to evaluate their potential in the reduction of ruminant methane emissions. The collection comprises thirteen contributions regarding different aspects of the topic mentioned above. Science-based results propose current solutions that can be implemented from a holistic One Health approach to focus on climate change from an animal–environmental perspective.
