In recent years, methane has been one of the most discussed and researched subjects due to its effect on global warming and climate change. Approximately 60-65% of methane production is of anthropogenic origin. Considering that half of this volume is generated by livestock breeding, both breeders and nutritionists show significant interest in this matter. Biotechnological and immunological methods as well as genetic improvement studies have the potential to reduce methane emission from ruminants, but as yet they are not commonly applied. For this reason, feeding strategies that are easier to implement in practice are being considered as having the potential to increase the effective usage of consumed energy while decreasing global methane emissions.
