About Ruminant Biotech

Who is Ruminant Biotech?

Ruminant Biotech is a New Zealand-founded agritech company developing an innovative solution to reduce methane emissions from livestock. Our goal is to deliver the world’s leading methane mitigation technology for grazing and pasture-based farming systems.

Clinical trials have shown our technology can reduce methane emissions by more than 70% for over 100 days from a single treatment.

What is our mission?

Our mission is to reduce methane emissions from livestock through a first-of-its-kind slow-release bolus. Our scientifically validated innovation provides long-lasting methane reduction, helping address the largest source of agricultural emissions.

Our Innovation

How does the bolus work?

Our patented technology uses a plant-based methane-inhibiting bolus that sits directly in the animal’s rumen.

The bolus releases a low, sustained dose of its active ingredient over 100 days. This ingredient targets methane-producing microbes in the rumen, significantly reducing methane emissions.

As the bolus gradually breaks down, the active ingredient is released before the casing is naturally passed or regurgitated.

How effective is the bolus?

Clinical trials have demonstrated methane reductions of more than 70% for over 100 days following a single application.

Treating just two cows with our technology can reduce methane emissions by approximately the same amount as removing an average family car from the road for one year.

Why is it suited to pasture-based farming?

Around 80% of the world’s cattle are raised in pasture-based systems.

Unlike feed additives that require controlled feeding environments, our single-application bolus is designed specifically for grazing livestock, delivering a consistent methane reduction solution that works wherever animals are farmed.

Does the bolus contain bromoform?

Yes. The active ingredient in our technology is bromoform (tribromomethane), a naturally occurring compound found in seaweed and in trace amounts in chlorinated drinking water.

Bromoform has been researched as a methane-reducing compound for decades and has been shown to be highly effective at the doses used for livestock methane mitigation.

When will the product be available?

We aim to commercialise our solution in New Zealand and Australia in 2026.

Recent investment is helping accelerate product development and regulatory pathways in additional priority markets, including Brazil, Europe, the United Kingdom, the United States, and Canada.

What makes Ruminant Biotech’s solution different?

While both boluses and bromoform-based methane reduction approaches have been researched extensively, Ruminant Biotech has developed a unique delivery system that combines the two into a long-lasting, practical solution designed specifically for grazing livestock.

Safety & Regulation

Is the product regulated?

Our product is currently progressing through regulatory review with New Zealand’s Ministry for Primary Industries (MPI) under the Agricultural Compounds and Veterinary Medicines (ACVM) Act.

This process includes independent assessment of animal safety, food safety, and efficacy to ensure the highest standards are met before commercial release.

Is the product safe for animals and the food supply?

Yes. Animal welfare and food safety are our highest priorities.

Bromoform is rapidly metabolised within the rumen, reducing methane production without harming the animal. Studies have shown no detectable residue in meat or milk when used at the effective doses. 

Why do some people have concerns about bromoform?

Questions about bromoform generally stem from:

  • Historical studies that used doses far higher than those used in livestock methane reduction applications.
  • IARC Classification. Bromoform is not classifiable by the International Agency for Research on Cancer (IARC), meaning there is insufficient evidence to determine whether it is carcinogenic.

We are committed to rigorous scientific evaluation, regulatory oversight, and transparency regarding the safety of our technology.
