Rumin8 achieves impressive 95.2% methane reduction in cattle trial at UC Davis

USA – Australian climate technology company Rumin8 has achieved a remarkable 95.2% reduction in methane emissions from cattle using its investigational veterinary product (IVP), according to a study by the University of California, Davis (UC Davis). 

The findings, published in Translational Animal Science, represent a significant milestone in methane mitigation efforts by Rumin8, which is provisionally approved for use in Brazil and New Zealand.

The study, titled “The effect of Rumin8 Investigational Veterinary Product – a bromoform-based feed additive – on enteric methane emissions, animal production parameters, and the rumen environment in feedlot cattle,” was led by L. Kelly and a team of researchers. 

It evaluated the impact of Rumin8’s IVP on enteric gas emissions, animal production parameters, and the rumen environment in feedlot cattle.

The trial involved 24 cattle divided into three groups, all fed a total mixed ration (TMR). Results demonstrated that total methane emissions decreased by 95.2%, while methane yield (g/kg dry matter intake) and methane intensity (g/kg average daily gain) were reduced by 93.0% and 93.4%, respectively. 

Notably, the study found no significant impact on animal production parameters or the rumen environment, further solidifying the product’s viability.

“These findings suggest that the Rumin8 oil IVP, containing synthetic bromoform (tribromomethane), has the potential to reduce enteric methane emissions significantly,” the study’s authors stated. 

Compared to other trials on synthetic halogenated methane analogues, the reductions observed with Rumin8’s IVP are among the most substantial recorded to date.

With global demand for meat and dairy projected to rise by 73% and 58%, respectively, by 2050, mitigating enteric methane emissions is a critical step toward reducing the environmental footprint of livestock production. 

Using a scalable and cost-efficient pharmaceutical approach, Rumin8’s technology directly addresses this challenge with its patented process that stabilises tribromomethane, an effective anti-methanogenic compound.

David Messina, CEO of Rumin8, hailed the UC Davis trial as a major validation of the company’s technology. 

“The UC Davis trial and its publication mark an important milestone for Rumin8. A globally renowned research institution has now confirmed the methane reductions we have observed in previous studies conducted in Australia, New Zealand, and Brazil.”

As Rumin8 continues its mission to revolutionise methane reduction in livestock, additional trials are underway in key cattle markets worldwide. 

The company is actively pursuing regulatory approval for its novel feed and water-delivered methane-reducing additives, positioning itself at the forefront of sustainable livestock production.
