Idea of killing cows to curtail methane emissions 'crazy'
Visiting US climate change expert Dr Will Happer says the idea of reducing cow numbers to greatly reduce methane emissions is crazy.
A methane inhibiting bolus specifically suited to New Zealand's pastoral farming system is awaiting regulatory approval for a launch late next year.
The slow-release, biodegradable bolus developed by Ruminant BioTech sits in the animal's rumen, releasing a controlled dose of a methane inhibitor for up to six months.
The latest trial on cattle reportedly showed impressive results, with a 75% daily methane reduction for 100 days from a single treatment.
The technology has received a $4 million funding boost from AgriZeroNZ, an industry joint venture between the Government and leading agribusiness companies in New Zealand, including Fonterra.
AgriZeroNZ chief executive Wayne McNee says the public-private joint venture is pleased to boost its investment in Ruminant BioTech by $4 million, on top of an initial investment of $1.8 million in April 2023.
"Ruminant BioTech is proving its technology is working - on animals and in New Zealand - so we're pleased to make this further investment to accelerate the development of a pasture-based solution for Kiwi farmers.
"The bolus has demonstrated world-leading results for methane reductin in a pastoral system in its latest animal trial, and we look forward to supporting the team to make their emissions reduction tool available to farmers."
Ruminant BioTech chief executive Tom Breen says his company is working with MPI on full product registration to enable the methane-inhibiting bolus to be used on New Zealand farms.
Breen says the company aims to be treating over 30 million cattle annually by 2030 and envisages this increasing to 100 million cattle within the next 10 years.
"This additional funding from AgriZeroNZ will help us accelerate our product and market development programme and build our first manufacturing plant in New Zealand to bring the product to market in late 2025, starting in Australia and followed by New Zealand, subject to regulatory approvals."
McNee believes the bolus could be a game-changing tool to help farmers reduce emissions without changing farming practices.
"The bolus application holds huge promise for providing Kiwi farmers with a solution that's practical and effective.
"It has the potential to be suitable for all ruminant animals, and due to its low touch nature, it's also a viable option for the likes of beef farmers who don't need to interact with their animals daily."
AgriZeroNZ has committed more than $34 million across a range of emissions reduction tools and technologies for New Zealand, farmers including novel probiotics, low methane pasture and methane vaccines.
"There isn't going to be a one-size-fits-all approach when it comes to reducing emissions across our agricultural sector," McNee says.
New Zealand's diverse cheesemaking talent shone brightly last night as the New Zealand Specialist Cheesemakers Association (NZSCA) crowned the champions of the 2026 New Zealand Cheese Awards.
Tracing has indicated that the source of the first velvetleaf find of the 2025-26 crop season, in Auckland, was likely maize purchased in the Waikato region.

With the forage maize harvest started in Northland and the Waikato, the Foundation for Arable Research (FAR) is telling growers of later crops, or those further south, to start checking their maize crop maturity about three weeks prior to when they think they will start silage harvesting.
Irrigation NZ is warning that the government's Resource Management Act (RMA) reform risks falling short of its objectives unless water use for food production and water storage infrastructure are clearly recognised in the goals at the top of the new system.
