Danish Cows Collapsing Under Mandatory Methane-Reducing Additive
Cow feed additive Bovaer meant to curb climate change seems to be killing some Danish dairy cows
Since October 1, 2025, when many Danish dairy farmers began incorporating the synthetic additive Bovaer (containing 3-nitrooxypropanol) into their cows’ feed—alarming reports have come in of animals suffering from: stomach cramps, fevers, miscarriages, drastic drops in milk production, sudden collapses and in some cases, the need to be euthanized.
The first farmer from Denmark comes forward and talks about sick and dead cows, after giving his cows the Bovaer poison. 10/28 25. Remember that waste products from Bovaer, are passed on in milk and meat.

In the shocking video below, Danish farmer Rene Lillehjælper discusses how her husband is driving their “cow ambulance” tractor— transporting yet another collapsed cow from their dairy farm—because of the “Bovaer Poison.”
Marketed as a “climate-friendly” methane reducer, this product—produced by the Dutch-Swiss giant DSM-Firmenich—became a legal requirement for Danish dairy farmers to add into their animal feed for 80 days or for their cows to be fed extra fat throughout the year.
Notably, farmers experimenting by removing Bovaer saw their herds recover rapidly, only for symptoms to return upon reintroduction. Yet, despite these red flags, authorities insist on pushing ahead, with an investigation only now underway.
These reports build on the concerns I outlined in my November 2024 investigation into Arla’s UK trials, where EFSA tolerance studies highlighted issues such as reduced feed intake, decreased organ weights (including ovaries and heart), and altered enzyme levels in cows at elevated doses—yet these effects were ultimately classified as “non-adverse” by regulators.
BREAKING: Methane-Reducing Feed Additive Trialled in Arla Dairy Farms
On November 26th, Arla Foods Ltd. announced via social media their collaboration with major UK supermarkets like Tesco, Aldi, and Morrisons to trial Bovaer, a feed additive, aiming to reduce methane …
What was even more troubling were the findings from my analysis of the safety assessment report, prepared by the UK’s Food Standards Agency (FSA) and Food Standards Scotland (FSS), reviewed by Animal Feed and Feed Additives Joint Expert Group (AFFAJEG) and the Advisory Committee on Animal Feedingstuffs (ACAF).
It stated: “In relation to safety studies for the consumer, a 2-year carcinogenicity study in Wistar rats showed “mesenchymal cell tumours were reported in 4 out of 49 females at the top dose of 300 mg/kg bw/day of 3-NOP given orally. Based on these results, the original study report concluded there was evidence of carcinogenicity in female rats.”
AFFAJEG noted potential for mesenchymal cell hyperplasia and benign tumours at high doses but, citing no malignant tumours or genotoxicity, concluded the additive is not carcinogenic at recommended inclusion rates.
ACAF echoed that the additive “can be considered safe for consumers.” Yet, their conclusion was seemingly contradicted by the following statement: “The additive should be considered corrosive to the eyes, a skin irritant and potentially harmful by inhalation.”
In a separate development, a May 2024 FDA letter addressed to Elanco US, Inc, (which has an agreement with DSM-Firmenich to market Bovaer) stated: “Based on a review of your data and the characteristics of your product, FDA has no questions at this time regarding whether Bovaer® 10 will achieve its intended effect and is expected to pose low risk to humans or animals under the conditions of its intended use.”
Ironically, the FDA letter included an attachment with the following warning:

It should be noted that Bovaer passed the FDA review in under 12 months—much shorter than industry standard.
Kjartan Poulsen, chairman of the National Association of Danish Dairy Producers, has received numerous calls from concerned farmers. “We have so many people who call us and are unhappy about what is happening in their herds,” he shared with TV 2.
He described the recurring issues as unusual and is urging reports of suspected Bovaer-linked miscarriages. Poulsen emphasized that any animal harm undermines the additive’s purpose: “This should give a climate effect – and if cows die from this, or they produce less milk, then the effect is minus.” He is calling for a temporary pause from Agriculture Minister Jacob Jensen and for farmers to cease use if welfare issues arise.
Approved by the European Commission in 2022 based on EFSA assessments, Bovaer was deemed safe for cows, consumers, and the environment, with claims of up to 30-45% methane reduction.
However, field experiences differ. Reports from Jyllands-Posten and TV 2 describe lower milk yields tied to miscarriages, plus collapses—some cows recovering with treatment but others needing to be euthanised.
Earlier whispers from Danish farmers included fevers, diarrhoea, mastitis, and even cow deaths attributed to Bovaer. One producer lost six animals in under a month. Critics label it “animal cruelty,” especially under mandatory use for farms with over 50 cows.
The Danish Veterinary and Food Administration acknowledges these reports and has enlisted Aarhus University to analyse real-world data, with initial findings expected after the 2025-26 new year.
The irony is stark: a product meant to “save the planet” for reducing methane is harmful to dairy herds, slashing productivity, and raising fears of contaminating the food chain—despite assurances it “breaks down fully” with no residues.
Yet, the true winners emerge clearly: DSM-Firmenich, cashing in on booming sales fuelled by mandates and climate subsidies, alongside powerhouse investors like BlackRock (holding ~3.3%) and Vanguard, who reap the rewards from this relentless Net-Zero drive.

The Climate Argument Against Livestock Doesn’t Add Up
From the Frontier Centre for Public Policy
Livestock contribute far less to emissions than activists claim, and eliminating them would weaken nutrition, resilience and food security
The war on livestock pushed by Net Zero ideologues is not environmental science; it’s a dangerous, misguided campaign that threatens global food security.
The priests of Net Zero 2050 have declared war on the cow, the pig and the chicken. From glass towers in London, Brussels and Ottawa, they argue that cutting animal protein, shrinking herds and pushing people toward lentils and lab-grown alternatives will save the climate from a steer’s burp.
This is not science. It is an urban belief that billions of people can be pushed toward a diet promoted by some policymakers who have never worked a field or heard a rooster at dawn. Eliminating or sharply reducing livestock would destabilize food systems and increase global hunger. In Canada, livestock account for about three per cent of total greenhouse gas emissions, according to Environment and Climate Change Canada.
Activists speak as if livestock suddenly appeared in the last century, belching fossil carbon into the air. In reality, the relationship between humans and the animals we raise is older than agriculture. It is part of how our species developed.
Two million years ago, early humans ate meat and marrow, mastered fire and developed larger brains. The expensive-tissue hypothesis, a theory that explains how early humans traded gut size for brain growth, is not ideology; it is basic anthropology. Animal fat and protein helped build the human brain and the societies that followed.
Domestication deepened that relationship. When humans raised cattle, sheep, pigs and chickens, we created a long partnership that shaped both species. Wolves became dogs. Aurochs, the wild ancestors of modern cattle, became domesticated animals. Junglefowl became chickens that could lay eggs reliably. These animals lived with us because it increased their chances of survival.
In return, they received protection, veterinary care and steady food during drought and winter. More than 70,000 Canadian farms raise cattle, hogs, poultry or sheep, supporting hundreds of thousands of jobs across the supply chain.
Livestock also protected people from climate extremes. When crops failed, grasslands still produced forage, and herds converted that into food. During the Little Ice Age, millions in Europe starved because grain crops collapsed. Pastoral communities, which lived from herding livestock rather than crops, survived because their herds could still graze. Removing livestock would offer little climate benefit, yet it would eliminate one of humanity’s most reliable protections against environmental shocks.
Today, a Maasai child in Kenya or northern Tanzania drinking milk from a cow grazing on dry land has a steadier food source than a vegan in a Berlin apartment relying on global shipping. Modern genetics and nutrition have pushed this relationship further. For the first time, the poorest billion people have access to complete protein and key nutrients such as iron, zinc, B12 and retinol, a form of vitamin A, that plants cannot supply without industrial processing or fortification. Canada also imports significant volumes of soy-based and other plant-protein products, making many urban vegan diets more dependent on long-distance supply chains than people assume. The war on livestock is not a war on carbon; it is a war on the most successful anti-poverty tool ever created.
And what about the animals? Remove humans tomorrow and most commercial chickens would die of exposure, merino sheep would overheat under their own wool and dairy cattle would suffer from untreated mastitis (a bacterial infection of the udder). These species are fully domesticated. Without us, they would disappear.
Net Zero 2050 is a climate target adopted by federal and provincial governments, but debates continue over whether it requires reducing livestock herds or simply improving farm practices. Net Zero advocates look at a pasture and see methane. Farmers see land producing food from nothing more than sunlight, rain and grass.
So the question is not technical. It is about how we see ourselves. Does the Net Zero vision treat humans as part of the natural world, or as a threat that must be contained by forcing diets and erasing long-standing food systems? Eliminating livestock sends the message that human presence itself is an environmental problem, not a participant in a functioning ecosystem.
The cow is not the enemy of the planet. Pasture is not a problem to fix. It is a solution our ancestors discovered long before anyone used the word “sustainable.” We abandon it at our peril and at theirs.

Why is Canada paying for dairy ‘losses’ during a boom?
This article supplied by Troy Media.
Canadians are told dairy farmers need protection. The newest numbers tell a different story
Every once in a while, someone inside a tightly protected system decides to say the quiet part out loud. That is what Joel Fox, a dairy farmer from the Trenton, Ont., area, did recently in the Ontario Farmer newspaper.
In a candid open letter, Fox questioned why established dairy farmers like himself continue to receive increasingly large government payouts, even though the sector is not shrinking but expanding. For readers less familiar with the system, supply management is the federal framework that controls dairy production through quotas and sets minimum prices to stabilize farmer income.
His piece, titled “We continue to privatize gains, socialize losses,” did not come from an economist or a critic of supply management. It came from someone who benefits from it. Yet his message was unmistakable: the numbers no longer add up.
Fox’s letter marks something we have not seen in years, a rare moment of internal dissent from a system that usually speaks with one voice. It is the first meaningful crack since the viral milk-dumping video by Ontario dairy farmer Jerry Huigen, who filmed himself being forced to dump thousands of litres of perfectly good milk because of quota rules. Huigen’s video exposed contradictions inside supply management, but the system quickly closed ranks until now. Fox has reopened a conversation that has been dormant for far too long.
In his letter, Fox admitted he would cash his latest $14,000 Dairy Direct Payment Program cheque, despite believing the program wastes taxpayer money. The Dairy Direct Payment Program was created to offset supposed losses from trade agreements like the Comprehensive Economic and Trade Agreement (CETA), the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Canada–United States–Mexico Agreement (CUSMA).
During those negotiations, Ottawa promised compensation because the agreements opened a small share of Canada’s dairy market, roughly three to five per cent, to additional foreign imports. The expectation was that this would shrink the domestic market. But those “losses” were only projections based on modelling and assumptions about future erosion in market share. They were predictions, not actual declines in production or demand. In reality, domestic dairy demand has strengthened.
Which raises the obvious question: why are we compensating dairy farmers for producing less when they are, in fact, producing more?
This month, dairy farmers received another one per cent quota increase, on top of several increases totalling four to five per cent in recent years. Quota only goes up when more milk is needed.
If trade deals had actually harmed the sector, quota would be going down, not up. Instead, Canada’s population has grown by nearly six million since 2015, processors have expanded and consumption has held steady. The market is clearly expanding.
Understanding what quota is makes the contradiction clearer. Quota is a government-created financial asset worth $24,000 to $27,000 per kilogram of butterfat. A mid-sized dairy farm may hold about $2.5 million in quota. Over the past few years, cumulative quota increases of five per cent or more have automatically added $120,000 to $135,000 to the value of a typical farm’s quota, entirely free.
Larger farms see even greater windfalls. Across the entire dairy system, these increases represent hundreds of millions of dollars in newly created quota value, likely exceeding $500 million in added wealth, generated not through innovation or productivity but by a regulatory decision.
That wealth is not just theoretical. Farm Credit Canada, a federal Crown corporation, accepts quota as collateral. When quota increases, so does a farmer’s borrowing power. Taxpayers indirectly backstop the loans tied to this government-manufactured asset. The upside flows privately; the risk sits with the public.
Yet despite rising production, rising quota values, rising equity and rising borrowing capacity, Ottawa continues issuing billions in compensation. Between 2019 and 2028, nearly $3 billion will flow to dairy farmers through the Dairy Direct Payment Program. Payments are based on quota holdings, meaning the largest farms receive the largest cheques. New farmers, young farmers and those without quota receive nothing. Established farms collect compensation while their asset values grow.
The rationale for these payments has collapsed. The domestic market did not shrink. Quota did not contract. Production did not fall. The compensation continues only because political promises are easier to maintain than to revisit.
What makes Fox’s letter important is that it comes from someone who gains from the system. When insiders publicly admit the compensation makes no economic sense, policymakers can no longer hide behind familiar scripts. Fox ends his letter with blunt honesty: “These privatized gains and socialized losses may not be good for Canadian taxpayers … but they sure are good for me.”
Canada is not being asked to abandon its dairy sector. It is being asked to face reality. If farmers are producing more, taxpayers should not be compensating them for imaginary declines. If quota values keep rising, Ottawa should not be writing billion-dollar cheques for hypothetical losses.
Fox’s letter is not a complaint; it is an opportunity. If insiders are calling for honesty, policymakers should finally be willing to do the same.
