Methane
Growing knowledge
A joint research programme between New Zealand and Ireland that started in February 2024 aims to better understand methane emissions from pasture-based systems.

Episode 21: Breeding for lower methane
How efficient can our cows get when it comes to methane? CRV and LIC are right now measuring emissions from the first daughters born in their methane research programme and testing the heritability of the trait. If the programme is successful, the companies hope to deliver a methane breeding value into their respective breeding indexes by 2026.
Is Breeding the Answer?
Finding a marker or proxy in a dairy cow that correlates with low or high methane is the big prize.

Tackling methane from the inside
Bringing a new science or technology product to market can be time-consuming and expensive but help is on hand to develop tools to reduce onfarm emissions. Delwyn DIckey takes a look at bolus technology to reduce methane emissions.
Methane-reducing supplements undergo NZ trials
Australian climate technology company Rumin8 has begun two safety and efficacy trials of its methane-reducing feed supplements in New Zealand.
The trials – one on beef cattle and one on dairy cattle – seek to test Rumin8’s product integration in NZ pasture-based systems.
