摘要：The increasing need for sustainable livestock production demands more research in the field of greenhouse gas (GHG), particularly methane (CH<sub>4</sub>), measurement and mitigation. Dietary interventions, management, and biotechnological strategies to reduce the environmental impacts and economic implications of enteric CH<sub>4</sub> emissions are needed. While the use of biotechnological interventions and management strategies can be challenging on a routine basis, feed additive supplementation appears to be the most researched, developed, and ready to use strategy to mitigate enteric CH<sub>4</sub> emissions. This paper discusses various recently developed feeding strategies to reduce enteric CH<sub>4</sub> emissions in livestock. Additionally, the manuscript reviews various technologies developed for CH<sub>4</sub> estimation since the accurate and reliable estimation of CH<sub>4</sub> emissions can be a limiting step in the development and adoption of any mitigation strategy.
