Livestock methane discharges - it's the cow belches causing the issue, not the flatulence
In a recent report published by Referencing Hub media, supported by DairyNZ, a potential solution to reduce the amount of methane belched out by cows has emerged. The focus is on altering the rumen fermentation process in cattle, which decreases the production of enteric methane - a potent greenhouse gas released during digestion.
The key to this solution lies in forages like plantain (Plantago lanceolata). This humble plant contains bioactive compounds that inhibit methanogenic microbes or redirect hydrogen use away from methane synthesis in the rumen.
Plantain offers several benefits. It affects fermentation pathways in the cow’s rumen, leading to lower methane production per unit of feed consumed. Additionally, it increases the digestibility and crude protein content of the forage, supporting better nutrient uptake and potentially reducing the need for supplementary feeds that might have higher emissions footprints.
By improving pasture species composition with low methane potential plants such as plantain and chicory, overall methane emissions from grazing livestock can be mitigated. This strategy is part of broader livestock emission reduction approaches, including use of improved pasture species, rotational grazing, and better fertilization practices to reduce not only enteric methane but also nitrogen-related emissions.
Incorporating plantain into cow pastures is a promising low-input method to reduce methane emissions. This aligns with ongoing agricultural research and climate action plans targeting methane reduction in ruminant livestock.
It's important to note that the majority of methane comes from the cow through breathing or belching. By addressing this issue, we can make a significant impact on reducing greenhouse gas emissions from the agricultural sector.

- This approach to reducing methane emissions in the agricultural sector, focusing on altering cattle's rumen fermentation process with forages like plantain, is an interesting intersection between science, health-and-wellness (of the livestock), and environmental-science (given its implications for climate change).
- By improving the environmental-science sector's understanding of the impact of bioactive compounds from plants like plantain on methane production, we can also promote fitness-and-exercise for the livestock, as improved digestibility leads to less need for supplementary feeds, thereby supporting the animal's health-and-wellness.
