Ruminants, including cattle, buffalo, sheep, and goats, are integral to global agriculture but are also significant contributors to greenhouse gas emissions, primarily methane. Methane is a potent greenhouse gas, with ruminant digestion accounting for up to 27% of global anthropogenic methane emissions . The microbial ecosystems within the ruminant digestive tract facilitate the fermentation processes that ultimately result in the formation of methane. Understanding and managing these microbial communities can play a pivotal role in reducing the environmental impact of livestock farming, contributing to broader climate change mitigation efforts.

This research topic aims to address the environmental impact of ruminant livestock through a detailed exploration of the microbiomes in their digestive systems. Recent advances in microbiology and genetics offer promising pathways to mitigate methane emissions. By leveraging techniques such as metagenomics, microbial ecology, and bioinformatics, researchers can uncover microbial pathways responsible for methane production. The goal is to identify and develop novel strategies, including dietary interventions, microbial modifications, and genetic approaches, to effectively reduce emissions. By synthesizing current research and technological advances, we can foster innovations that align agricultural practices with environmental sustainability.

This topic seeks a comprehensive understanding of the interaction between ruminant microbiomes and methane emissions, inviting contributions that address:

o Multi-species microbial pathways and interactions leading to methane production.
o Dietary influences and mitigation strategies on ruminant microbial ecosystems.
o Phytochemical compounds effect methane mitigation.
o Host genetics and environmental factors affecting microbial communities.
o Innovative microbial-based interventions exploring microbial mechanisms and genetic modifications for emission reduction.
o Sustainable livestock practices to reduce environmental impacts

We welcome original research articles, reviews, and perspectives that provide insights into these areas. By doing so, we aim to compile a robust body of knowledge that can inform sustainable livestock management practices and contribute to global efforts against climate change. Submissions must be hypothesis driven and investigate molecular, genetic, and biochemical mechanisms. Descriptive metagenomic screening studies without further experimental validations will be out of scope for this Research Topic.
