Methane Reduction Dietary Aids: Our Position Statement
In the ongoing quest to reduce methane emissions from cattle, the use of feed additives is being considered by government bodies and food companies as a potential solution. However, a leading organisation, Pasture for Life, views this approach as a short-term intervention at best and a 'business as usual' approach that overlooks the need for more research into low input systems and farm level emissions of fully pastured systems.
Professor John Newbold will delve deeper into this topic in a webinar scheduled for March 2024. His discussion is expected to highlight the potential side effects on animal welfare that have been reported in trials, such as reduced feed intake, altered organ weights, reproductive and enzymatic changes with high doses, and unknown long-term impacts.
These concerns are not limited to methane-inhibiting feed additives alone. The use of any feed additives can cause unintended side effects on other issues such as animal welfare or biodiversity. For instance, there is a lack of direct evidence on the impact of these additives on biodiversity, but concerns stem from the possibility that focusing solely on technological fixes may overlook broader sustainable farming practices that benefit ecosystems.
As we move towards a more sustainable future, it is crucial for government and businesses to support more research into these low input systems. A more comprehensive understanding of farm level carbon cycles is needed to ensure sector-level interventions deliver the broadest impact.
In the long run, methane-inhibiting feed additives are promising but not yet fully validated as a long-term solution to methane emissions. The unknown long-term effects on animal health and the risk of technological dependency suggest they should be part of a multi-faceted approach rather than a standalone fix. Sustainable livestock management practices, alongside these additives, are likely necessary to balance emission reductions with animal welfare and ecosystem health.
By reconnecting farming with the land, farmers can deliver greater profitability, financial resilience, flourishing biodiversity, a restored carbon cycle, and the production of nourishing meat and milk. Pasture for Life certified farms, which are prohibited from using feed additives and must only feed pasture and forage, are a testament to this approach. These farms are required to match the number of animals to the carrying capacity of the land that feeds them, ensuring proper ecological functioning takes place.
As the scientific understanding of age-old farming systems is still in its infancy, it is essential to approach the use of feed additives with caution. The goal is not just to reduce methane emissions but to do so in a way that supports the health and welfare of animals, promotes biodiversity, and ensures the long-term sustainability of our farming practices.

- Recognizing the potential side effects on animal welfare, the discussion by Professor John Newbold in the upcoming webinar will emphasize these concerns, alongside reports of reduced feed intake, altered organ weights, reproductive and enzymatic changes with high doses, and unknown long-term impacts, related to methane-inhibiting feed additives.
- While methane-inhibiting feed additives show promise, their unknown long-term effects on animal health and the risk of technological dependency suggest they should be part of a multi-faceted approach, balancing emission reductions with animal welfare and ecosystem health.
- As the scientific understanding of age-old farming systems is still developing, it is essential to approach the use of feed additives with caution, in light of research on their potential impact on animal welfare, biodiversity, and long-term sustainability.
- In the quest for a more sustainable future, it is critical for government and businesses to support more research into low input systems, ensuring a comprehensive understanding of farm level carbon cycles to deliver the broadest impact.
- Leaning towards sustainable livestock management practices, such as pasture-based systems like Pasture for Life certified farms, can lead to greater profitability, financial resilience, flourishing biodiversity, a restored carbon cycle, and the production of nourishing meat and milk, without relying on feed additives.
