Opportunities to reduce methane emissions (CH4 ) in the digestive processes of ruminant animals. Review

Abstract

The article covers an extremely important problem concerning the pollution of the environment with greenhouse gases, considered one of the causes of global warming of the Earth. The greenhouse gas (GHG) methane is continuously released as a by-product of enteric fermentation, which is largely produced by the digestive system of ruminants. Methane reduction from ruminants is not a new area of research. However, the number of scientific publications in this field has increased rapidly over the past two decades due to the emphasis placed on the effects of greenhouse gas emissions on climate change. The review aims to explore different options and strategies for reducing methane emissions in the digestive process of ruminants. In conclusion, the authors believe that the studies done so far are substantial but insufficient to draw definitive conclusions. Further studies are needed to develop a coherent system and strategy to reduce methane emissions from ruminants.
