COMMENT: Bovaer is added to cow feed to reduce methane emissions. Does it get into milk and meat? Is it harmful for humans?

There has been an enormous amount of misinformation about the safety of 3-NOP, with some labelling milk from herds fed the additive as "Frankenmilk." Others have been concerned it could make its way to humans via beef. The bottom line is that 3-NOP is safe. Let's unpack some of the major misunderstandings.

Study indicates methane emissions from dairy farms higher than previously thought

To reach net zero by 2050, the UK must reduce greenhouse gas emissions from agriculture and methane emissions from farm livestock pose a thorny problem. Ruminants such as cattle and sheep emit methane from their digestive systems and their manure. Scientists are trying to find ways to reduce these methane emissions without wiping out large parts of […] Read more



Producers will soon be able to source a feed additive to cut cattle methane production.

First-of-its-kind cattle methane limiter approved for Canada

Bovaer feed additive already has stamp of approval in other countries

Glacier FarmMedia – A feed ingredient designed to reduce methane emissions in beef and dairy cattle can now be used in Canada. Bovaer neutralizes methane in the rumen. When microbes break down feed, hydrogen and carbon dioxide are released. These two gases are combined in the presence of an enyzme. Bovaer works by suppressing the […] Read more

Developers of methane emission reduction techniques win innovation award

A University of Guelph innovation that uses genetic selection methods to reduce methane emissions in dairy cattle has received the University’s Innovation of the Year Award for 2023.  The annual awards from the Office of Research and the Research Innovation Office recognize researchers for creative strategies or products that make a difference in people’s lives.  The team behind this year’s winning […] Read more


The livestock industry has already set voluntary emissions reduction targets.

Government looks for ways to cut cattle’s methane emissions

Ottawa announces Agricultural Methane Reduction Challenge

Glacier FarmMedia – Ottawa is making $12 million available to help find ways to reduce methane emissions from cow-calf, dairy and feedlot operations. The Agricultural Methane Reduction Challenge is part of the federal government’s plan to reduce overall methane emissions 40 to 45 per cent below 2005 levels by 2030 and to be net-zero by […] Read more

Dairy Farmers of Canada aims to be carbon neutral by 2050.

Feds offer funding to reduce methane

Up to $12 million available to producers, companies and organizations

The federal agriculture department recently launched the Agricultural Methane Reduction Challenge for cow-calf, dairy and feedlot producers. The objective is to stimulate innovations that will reduce methane emissions in cattle.  Up to $12 million will be awarded to innovators who advance low-cost and scalable practices, processes and technologies. Why it matters: Cattle are major contributors […] Read more
