AgriZeroNZ puts millions into US start-up reducing methane emissions
'They're developing two different things,' he said.
'One is an enzyme blend that you mix into supplementary feed, which looks to reduce emissions by about 80% while at the same time improving milk yield and meat yield.
'The great benefit for a farmer would be if you can make more meat and milk with the same amount of feed, and also reduce emissions, that would be ideal.
'This [enzyme] still needs to be fed as a feed supplement, but only a small amount once a day.'
The enzyme could work for dairy cows, which come into the milking shed once or twice daily.
'The company is also looking to develop probiotics which would enable it to be fed less often, maybe weekly or monthly, which could then be used for a much more extensive system like a beef or sheep system.'
McNee said Hoofprint representatives had been visiting New Zealand looking for research partners to run an animal trial.
Methane from livestock makes up almost half of New Zealand's annual tally of greenhouse gas emissions.
AgriZeroNZ is a joint venture aimed at getting that tally down by investing in new methane-cutting products.
It is half owned by the Government and half owned by a group of companies including The a2 Milk Company, ANZ, ASB, BNZ, Fonterra, Rabobank, Ravensdown, Silver Fern Farms and Synlait.
Its latest investment takes AgriZeroNZ's total investment in Hoofprint to $13 million, its largest investment to date.
It has also invested in several other potential methane-cutting products, including another US start-up, ArkeaBio, trialling a methane vaccine.
The first product likely to reach farmers is a slow-release bolus out of New Zealand that releases bromoform into an animal's gut.
New Zealand company Ruminant Biotech has developed a small metal capsule (bolus), which delivers a potent methane-squashing medicine, which McNee said should be ready in 2026, before Hoofprint's enzymes.
Fonterra has also been trialling its own 'Kowbucha' probiotic to cut methane from dairy cows.
Meanwhile, New Zealand scientists have been working on their own vaccine and methane inhibitors for years,
McNee having a range of alternatives on the market would help keep prices competitive for farmers.
There was also potential for additional benefits from adding together different products - but it was too soon to know whether that would work, he said.

Climate change and farming: New Zealand beef sector likely first in line for emissions-reducing livestock pill
AgriZeroNZ first invested $1.8 million into Ruminant BioTech's product in April 2023, followed by $4m to accelerate its commercialisation in August. AgriZeroNZ chief executive Wayne McNee said the company was planning a limited release for beef cattle, once it was approved by the regulator. McNee said Ruminant BioTech was likely to be the first of these products in the market. 'It's a bolus many of you will have heard of, containing bromoform. 'The benefit of a bolus, obviously, is that you can administer it once, it lasts for at least 100 days and reduces methane by 70% or so over that period. 'And the current thinking is to probably administer one of these [boluses] to an animal during its lifetime and you average out the benefit of that over the period of that beef animal's life.' Ruminant BioTech's bolus won a prototype category innovation award at Fieldays near Hamilton in June. Assessing new bolus for use on-farm Ruminant BioTech's bolus contained Tribromomethane (bromoform), a chemical compound that could be found in marine algae, phytoplankton or as a byproduct of chlorinated drinking water. It applied to register trade names for two products, the 'Calm A Cattle Bolus' last September and 'Emitless' in May. Ruminant Bio Tech's R&D team holding boluses, designed to curb methane emissions in cattle, in front of the lab team producing a batch of boluses. Department of Internal Affairs information showed Emitless was a 172g oral bolus containing 48g of Tribromomethane. Users were instructed not to use the product in cattle intended for reproduction, or in cattle intended to produce milk for human consumption – whereas Calm A Cattle Bolus was a 165g bolus containing 36g of Tribromomethane, intended to reduce enteric methane emissions in cattle for up to four months. Last week, the Environmental Protection Authority said it determined that the inhibitor – containing 50-70% tribromomethane as the active ingredient – fit within the scope of the veterinary medicines group standard, under the Hazardous Substances and New Organisms Act (1996), and did not require an individual approval. Before the product could be used in New Zealand, though, it would require registration under the Agricultural Compounds and Veterinary Medicines Act (1997), which was administered by the Ministry for Primary Industries. New Zealand Food Safety deputy director-general Vincent Arbuckle said it had received and was assessing the application for registering Ruminant BioTech's 'Emitless' product. Arbuckle said the product was an intraruminal bolus for reducing enteric methane in cattle weighing between 350kg and 450kg for up to four months. McNee said it expected a result from the regulator soon. 'It's going through regulatory process at the moment and hoping to be available later this year or, worst case, early next year,' he said. 'Certainly by next year and over the next few years, we'll see one or two products, maybe three products come into the market each year. 'That's what the companies are telling us.' New emissions reduction tools 'coming fast' McNee said that in future, farmers will have a range of emissions-reduction tools to choose from. 'If there's a productivity improvement, it may be relatively straightforward to get uptake,' he said. 'But in other cases, if it's pure methane reduction, then at the end of the day, somebody's going to have to pay for that. 'There are a number of processors, certainly the ones that have invested in us, who are talking with companies offshore to look at the potential to provide incentives to farmers to take up those tools.' Also speaking at the red meat sector conference in Christchurch this month, Dr John Roche, the chief science advisor for the Prime Minister and the Ministry for Primary Industries, said progress had accelerated. 'Incredibly exciting,' Roche said. 'I've sat in front of select committee[s] [at Parliament] for the last several years talking about these technologies, and I kid you not, two or three years ago I was promising I'm reasonably confident they'll be here by 2030. 'Two years later, I'm saying we will have a bolus that reduces methane by 70% in dry stock, slow-release over 120 days and it will be released either later this year or early next year. 'These technologies are coming fast and more of them are becoming available.' Company records showed Ruminant BioTech Corp's main shareholders were Rosrain Investments, which owned 44% of the business. It had two company directors from New Zealand and two from Australia. Other backers included New Zealand Trustee Services, Crown Terrace Investments and New Zealand Green Investment Finance. The latter is a government fund towards low-emissions projects that the Government announced in April that it will shut down. – RNZ

Beef farmers likely first in line for emissions-reducing livestock pill
Photo: RNZ/Susan Murray Industry-government venture AgriZero is hinting that New Zealand beef may be the first agricultural sector to gain access to tools like a new methane-reducing pill for livestock - and soon. Ruminant BioTech was developing a slow-release bolus, or pill, to be fed to livestock. Recent trials on New Zealand farms resulted in a reduction of methane emissions. It was one of AgriZero's 10 investments towards reducing agricultural emissions. AgriZero first invested $1.8 million into Ruminant BioTech's product in April 2023, followed by $4m to accelerate its commercialisation in August. Chief executive Wayne McNee said the company was planning a limited release for beef cattle, once it was approved by the regulator.

The world wants our excellent butter
One of our favourite butter brands recently took home a prestigious award from the International Cheese and Dairy show, the oldest and largest such show in England. According to the judges, compared with other competing countries, our butter is creamy, velvet and rich, without being greasy. It carries flavour and can soak up all the spices, aromatics, and seasoning in our cooking. It is more yellow and has a higher fat content than the pale, grain-fed American butter — consequently, along with the judges and countless top chefs, they just can't get enough of it. Butter is one of the purest foods in the world, and we make lots of it. New Zealand is the largest exporter of butter, and last year we exported 525,000 tonnes which is a third of the global market and worth $2.54 billion, making it our second-largest export earner. China is our biggest buyer, purchasing $786 million worth in 2024. Chinese people have some trust issues with their dairy products, and New Zealand is the most trusted and the butter considered to be of high quality. Other large importers of butter are the US, Australia and the Philippines, but it's almost unbelievable that we import about $3.69m worth each year, mainly from Denmark, India, Australia, France and Fiji. The dairy export industry started from humble beginnings, with a few barrels of salted butter manufactured at the Edendale Dairy Co shipped to England on board SS Dunedin in 1882 alongside its cargo of frozen mutton. Today the industry employs 55,000 people, there are seven different brands of butter and New Zealanders on the global scale are the highest consumers of the product. Hogging various media headlines at the moment is the price, as it is at an all-time high, and some seem to be trying to give Fonterra a guilt complex as if it sets the price and is responsible — but it is the global auction that sets the price. Fonterra's chief financial officer Andrew Murray stated our butter costs a lot less than you pay in Europe. Is there an irony in all this? Farmers have been improving their environmental image, animal welfare, our clean and green brand and, of course, animals are grass-fed, with the long-term view that premier products attract high-spending customers which in turn help not only the farmer but the country — but we could struggle to afford what we produce. Butter is 49% higher than a year ago and could it be beef and lamb next, which is 50% higher than five years ago. However, what goes up usually comes down.
