Mitigating methane (CH4) losses from ruminants is generally required to minimize global greenhouse gas emissions and
to enhance animal performance by improving feed conversion efficiency. The production of CH4 has been reduced using
various techniques which affect the metabolism, microbial population and/or animal digestive physiology. These
technologies can be broadly classified into improved nutrition and fermentation modification strategies. The nutritional
approaches include dietary manipulation and feed additive supplementation. This paper presents some promising
methane mitigation options with special consideration to ruminant dietary modification
