What is Bovaer?
Bovaer is a synthetic feed additive developed by DSM-Firmenich to reduce enteric methane emissions from ruminants like cows. It works by inhibiting a specific enzyme in the cow's digestive system, which is responsible for the final step of methane production. Feeding just a small amount of Bovaer daily can significantly lower methane output, with trials showing reductions of up to 30% or more. While approved for use in over 65 countries, including the EU, it is not used in every dairy system. The additive is not passed into the milk or meat, ensuring there is no consumer exposure.
The Kerrygold Approach: Grass-Fed and Natural
Kerrygold's business model is rooted in traditional Irish dairy farming, which relies on a grass-based system. For most of the year, Irish dairy cows graze outdoors on lush, green pastures, and during the winter months, their diet is supplemented with silage made from summer grass. This farming approach contrasts with the more intensive, confined-system farming where feed additives like Bovaer are typically easier to implement.
Kerrygold is also a member of Ireland’s Origin Green food and drink sustainability program. This national scheme ensures that member farms adhere to specific standards regarding animal welfare, land management, and sustainable production. The reliance on natural pasture grazing means that the large-scale integration of a feed additive like Bovaer, which is most effective when consistently mixed with feed in a controlled environment, presents logistical challenges in a predominantly grass-fed system.
Comparison Table: Kerrygold vs. Bovaer-Using Dairy Farms
| Feature | Kerrygold (Irish Grass-Fed) | Bovaer-Using Dairy Farms (Confined/Mixed Feed) |
|---|---|---|
| Primary Diet | Outdoors grazing on lush, Irish grass for most of the year; supplemented with grass silage in winter. | Higher percentage of supplementary feed, making additive integration easier. |
| Farming System | Predominantly pasture-based, non-intensive. | Often more intensive, confined systems. |
| Methane Reduction Method | Relies on the natural efficiency of a grass-based diet and sustainable farming practices. | Directly adds Bovaer to feed, inhibiting methane-producing enzymes in the cow's rumen. |
| Additives Used | Minimal supplementary feed for health; no Bovaer. | Uses Bovaer in the daily feed mix. |
| Logistical Challenge | Difficult to consistently administer a feed additive to cows grazing freely. | Easily incorporated into existing indoor feeding systems. |
| Regulatory Context | Adheres to Ireland’s national Sustainable Dairy Assurance Scheme. | Must comply with regulatory approvals for Bovaer, such as those from EFSA in Europe. |
Logistical and Ethical Considerations
The use of Bovaer is a complex issue with multiple facets. For some farmers, particularly those in more intensive systems, it provides a tangible way to reduce their environmental footprint and align with climate goals. However, as highlighted by organic producers, there are ethical and production considerations surrounding synthetic additives. Kerrygold’s commitment to its grass-fed model, as well as the practical difficulties of administering a daily feed additive to free-roaming herds, has influenced their decision to not use Bovaer.
How does this affect consumers?
For consumers, the decision by Kerrygold not to use Bovaer means their butter remains a product of traditional, grass-fed Irish dairy farming, without the use of this specific synthetic additive. Since Bovaer does not enter the milk or meat supply chain, consuming dairy products from farms that do use it is considered safe by regulatory bodies. The presence of Bovaer is primarily an environmental and production concern, not a food safety one. Therefore, a consumer's choice between Kerrygold and a brand that uses Bovaer is more about ethical farming practices and personal preferences rather than safety. The transparency provided by Kerrygold and the ongoing public discourse on such additives allows consumers to make informed choices that align with their values.
Conclusion
Based on official statements from Kerrygold, their butter does not contain Bovaer, the methane-reducing feed additive. This is primarily due to their commitment to traditional grass-fed Irish dairy farming, which is inherently different from the intensive, mixed-feed systems where Bovaer is more readily used. While Bovaer is a scientifically-proven method for reducing enteric methane and is safe for consumption, Kerrygold’s production model and sustainability practices rely on natural, pasture-based grazing. This distinction allows consumers to choose a product that aligns with their preferences for specific farming methods and environmental approaches. The issue highlights the diversity of strategies within the dairy industry to address environmental challenges, from relying on traditional grass-based methods to adopting modern feed additives.

What do Kerrygold's farming practices involve?
- Kerrygold's cows graze outdoors on lush Irish pastures for most of the year, with their diet supplemented by silage during winter.
- Farmers rotate cows through different paddocks to ensure high-quality grass consumption.
- The farming system is less intensive compared to many global dairy operations, prioritizing animal welfare.
- Farms are audited under Ireland's national Sustainable Dairy Assurance Scheme.
- Hedgerows are maintained to support biodiversity.
Is Bovaer used in Ireland at all?
- While Bovaer is authorized in the EU and some trials have occurred, widespread commercial use is problematic in Ireland's predominant grazing system.
- Challenges exist in consistently delivering the additive to freely grazing cows.
- An established business model for farmers using the material is still developing.
Is Bovaer safe for consumers?
- Regulatory authorities in both the EU (EFSA) and the UK (FSA) have approved Bovaer for use, confirming its safety for animals and consumers.
- It is fully metabolized by the cow and does not pass into the milk or meat.
- Over 150 trials have been conducted to ensure its safety and effectiveness.
Why are some people concerned about Bovaer?
- Concerns often center on its synthetic nature and its use in large-scale, intensive farming, which contrasts with traditional, organic, or grass-fed systems.
- The debate includes the environmental impact of its production and logistical challenges.
- For many, the focus is more on aligning with traditional or organic farming ethics rather than food safety.
Is Kerrygold transparent about their production?
- Yes, Kerrygold provides information on its website about its grass-fed farming system and participation in Ireland's Origin Green sustainability program.
- They have also confirmed directly via social media that Bovaer is not used in their supply chain.
- Ingredients for their products are listed on packaging and online.
What are the ingredients in Kerrygold butter?
- According to product listings, Kerrygold butter contains cream (milk) and salt.
- It is known for its grass-fed milk, which gives it a distinct flavor and golden color.
- There are no added preservatives or coloring.
Can other dairy products contain Bovaer?
- Yes, other dairy products sourced from farms using the additive could potentially be made with milk from Bovaer-fed cows.
- Some companies, like Arla in Europe, have run trials or used Bovaer, and products made from their milk could contain milk from Bovaer-fed cows.
- The use of Bovaer depends on the farming system, feed strategy, and corporate decisions.
