Building a growing animal agtech company with Stefan Scherer, SmaXtec

Sustainability in dairy is usually talked about in ecological terms. But a farm has to be economically sustainable. As my guest puts it: “I can have the best farm in the world. If it goes out of business, it’s not sustainable. And the best methods don’t help if they don’t survive the everyday operation.” Today I am joined by Stefan Scherer, former CEO and now a board member of smaXtec, the Austrian company behind an intraruminal bolus that monitors dairy cow health around the clock. Stefan grew up in the Alps. His grandparents ran a small dairy farm and his father sold cheese. But he came to agriculture as a physicist and computer scientist. His first startup taught him a hard lesson. He built 3D measurement technology for electron microscopes, convinced people would love it, “just to realize that nobody really needs it.” Since then he has started with the customer: “Where is the value at the farmer? What’s their pain?… and then you can match your technological offers to solve those pains… but not the other way around.” That philosophy runs through our conversation. “Money is a necessity, but money doesn’t solve the problem. It’s always the people executing.” People buy from people, and after the product itself, support is what customers value most. “You cannot dump technology into an industry without really providing the support and guidance on how to turn it into actual value.” At its simplest, Stefan says, “you need a happy and healthy cow. That one will give you the best milk in the long term.” The bolus can warn a farmer that a cow is likely to get sick within four days, which lets farms move from treating sick cows to preventing illness. That shift depends on trust. The biggest lever, Stefan argues, is longevity. Cows only become truly profitable from their third lactation. Despite whether a cow is in a housed system in Wisconsin or grazing in New Zealand, “a mastitis is a mastitis.” We also discuss why investment in agtech has been so difficult. Stefan points to the alternative proteins, when “what was promised to investors didn’t turn into reality.” He sees the future in a meeting point between traditional investors in land and machinery and venture capitalists expecting 15x returns in three to five years. On data, Stefan argues that the industry already has a lot of data points. Too much of that data is locked inside individual companies’ ecosystems, and a more open framework for sharing would have a faster impact than adding ever more sensors. As smaXtec’s ability to track a bluetongue wave moving through herds shows, the potential is huge. But so are the questions about ownership, regulation and who data should be shared with. Looking ahead, Stefan’s dream is an AI companion for every farmer. His advice to farmers: “Start working with the tools with AI, because even if it’s not perfect yet, things will accelerate so much that you can’t wait until the perfect system is ready for you… you need to gain experience now.” A self-described “notorious optimist,” Stefan believes that “if we do the right things, there’s a bright future” for dairy, agriculture and humanity.

The geopolitics of climate change with Arthur Snell, RUSI

We are living in a time of greater geopolitical disorder, and that disorder is “coupled with and feeding off” climate change. During the green revolution following WW2 agricultural productivity grew steadily. In the last couple of decades, that has no longer been the case. Farmers across Europe and North America have just come through another year of extreme heat and drought. Meanwhile, the trade systems that move food around the world are being strained by conflict, tariffs, and the weaponization of trade routes. Today I am joined by Arthur Snell, a former British diplomat who spent two decades in the Foreign Office. He served in Afghanistan, Iraq, Yemen, Nigeria and Zimbabwe, led the UK’s global programs countering violent extremism, and was High Commissioner to Trinidad and Tobago. He is now an Associate Fellow at RUSI and a geopolitical consultant, writer and podcast host. He is also the author of Elemental: The New Geography of Climate Change and How We Survive It. Food has always been traded globally, from Egyptian wheat feeding Rome to today’s commodity markets. Arthur argues the lesson from history is that “functional and relatively free-flowing world trade is absolutely crucial to a functional food system.” When barriers and dysfunction are introduced, whether through tariffs, geopolitics, climate shocks or war, food systems can break down. The impacts are felt most keenly where resilience is lowest. In Egypt, for example, subsidized bread is a key element of social stability. Climate change is also redrawing the map. In the Sahel, the Sahara is advancing. In Russia’s sparsely populated far east, Chinese workers are moving north to expand agribusiness on land that was once too cold to farm. Coastlines are eroding, and Pacific atoll nations face losing theirs entirely. At the same time, long-standing norms around borders and territorial sovereignty are weakening, from Ukraine to Greenland. We also discuss asymmetric warfare. Cheap drones, together with a willingness to absorb suffering, can now challenge the most sophisticated militaries on Earth. And when ships no long pass freely through the Straits of Hormuz and Bab-el-Mandeb, the effects are felt globally. Arthur’s central message is one of urgency, not despair: “The technologies that are needed for us to get out of this mess all exist already… We are already starting on that journey. What we’re not doing is doing it quick enough… It is not that it can’t be done… We have the ability, we just need to get going a bit quicker.” Send us Fan Mail

We don’t need a perfect answer. We need a reliable answer with Tom Sturgess, Methane Mitigation Ventures

Consumers will pay a premium for climate-friendly red meat, but not the way you’re thinking about it. This premium is not a mark-up on any single purchase. It’s customer loyalty to the retailer selling the product. A brand with integrity keeps customers coming back, and the retailer, the real customer, captures that lifetime value. Today I am joined by Tom Sturgess, who has been involved in red meat production since 1985. Thirty years ago he moved to New Zealand and taught himself sheep and beef farming. Today his farms produce around 70,000 tope quality lambs a year that earns a 40 to 50% market premium. Tom has also spent over a decade investing in to reduce the carbon footprint of livestock production includeing funding a team developing a low cost feed additive with a target price of 1.5 to 3 cents per animal per day. Tom acknowledges that ruminant maths is challenging. That said, he also agues that research system is too often its own worst enemy. The combiantion of the cost and need to conduct many large in vivo trials is crippling to many innovtaors. Rapid, small-scale animal trials that give a reliable, roughly 80% answer, are needed so researchers can learn and iterate before committing to expensive formal studies. Tom sees the California dairy industry as the standout success story. The combaination of legislation and state funding behind them have enable California dairy farmers to cut emissions by close to 50% in around seven years. He also praises Australia as offering the most supportive research and regulatory pathway he has experiinced. We discuss when innovations are ready for venture capital, and why funders need to monitor closely rather than impose rigid milestones. Tom also explains why genetics, feed, forage and husbandry solutions will stack together, and why, in the end, it all comes down to people and teams. Send us Fan Mail

Profitable climate solutions for small holder farmers with Devdut Dalal Mitti Labs

Rice feeds more people than any other crop, and it is grown in a way that is quietly expensive. Globally, a third of all groundwater extraction goes to rice farming. And because those fields sit flooded for weeks at a time, the resulting anaerobic conditions produce methane. Rice accounts for around 2% of global greenhouse gas emissions, comparable to the aviation industry, and about 12% of all methane. In India, rice covers some 40 million hectares, a quarter of the country's agricultural land, in a nation that is already deeply water stressed. Today I am joined by Devdut Dalal of Mitti Labs (https://www.mittilabs.earth/), who is working on addressing water use efficiency and methane for smallholder farmers. The practice change is alternate wetting and drying. The challenge is implementing it across tens of thousands of farmers with an average farm size of one hectare. Exposing the soil to air a few times a season reduces water consumption, reduces methane, and does not reduce yield. Their secret to scaling is to do one thing well, focus on that, and keep things simple. "We're going to do one good thing across 100 farms. Get that one thing right. Prove the work was meaningful and impactful and reward worthy. And then you can stack good thing number two, good thing number three, good thing number four." — Devdut Dalal Getting 70,000 farmers across more than 100,000 hectares to adopt a new practice took four things: trust, borrowed from local field agents and NGOs who already have relationships in those communities; demonstrated proof, by asking a farmer with four acres to try it on one; ongoing support; and an incentive. Trust, proof, support and reward. It is simply a matter of creating value for farmers. That value comes from carbon credits. Companies with scope three commitments pay for the methane reductions, and the farmers are paid for the credits. Mitti has just signed an agreement with Google to supply one million credits by 2030, one of the largest super pollutant mitigation deals announced to date. We also discuss the satellite technology that makes monitoring possible at this scale, the delayed and increasingly unpredictable monsoon, and the energy-water nexus that should make state governments the most motivated party of all.

Government policy to address today's food system challenges with Robert Bonnie former Undersecretary of Agriculture, USDA

Managing and mitigating risk runs through my whole conversation with Robert Bonnie. Since the Dust Bowl, USDA policy, the Farm Bill and especially crop insurance have given US farmers a safety net that shares the risk of growing the nation's food. But farming keeps getting riskier. Climate change, volatile input costs and commodity prices, access to labour, access to markets and geopolitical instability are all shifting more than they used to. Too often farmers and ranchers are left to carry that extra risk alone. Governments have a unique role to play here. "The question from a policy standpoint is how do you drive policy that is focused on the outcomes that folks want and that allow for the type of innovation you need in the private sector, and that de-risk the adoption of many of these practices, recognizing we actually don't have all the answers right now. We need to allow for innovation. How do we do that in a way that works for farmers while it also works for the public?" Robert Bonnie At the same time, new technologies and innovation are opening up ways to manage that risk that weren't available a decade ago. We already know that no-till, cover crops, crop rotation and better grazing make yields more stable through drought and flood. During the Biden administration, Robert tried to design crop insurance that would reward growers for adopting those practices because they reduce yield risk. "It's very hard to do. It's possible, I think, with new technology." That's now his focus at Sage, a startup using AI on soil data to support better insurance products and farm lending. He also draws a lesson from overseeing the US Forest Service in the Obama years. Every year firefighting took more of the budget, and less was left for the land management that stops catastrophic fires in the first place. Agriculture risks the same trap: paying for the disaster instead of the preparation. Robert served 12 years as a political appointee in the Obama and Biden administrations, most recently as USDA Under Secretary for Farm Production and Conservation. He is now a visiting scholar at UC Berkeley's Stone Center for Environmental Stewardship. Send us Fan Mail

Beef sustainability, methane, and efficiency with Tom McDonald, US Roundtable for Sustainable Beef

Beef sustainability frequently gets framed as something imposed on the ranchers and the industry from outside—regulatory requirements, consumer pressure, climate obligations driven by environmental groups and activists, leaving the industry industry to respond or resist. But this frame misses something fundamental. My guest today, Tom McDonald, is chair of the U.S. Roundtable for Sustainable Beef and sustainability lead at Five Rivers Cattle. His reframing is powerful because it turns sustainability from an external demand into something the beef industry has been pursuing for generations. As he puts it: "Sustainability is a journey and not a destination." The three pillars are simple: environmentally sound, socially responsible, economically viable. But McDonald breaks this down further into language that resonates with producers: efficiency. The beef industry has been working on efficiency for decades. Feed efficiency. Land efficiency. Resource efficiency. When you talk to ranchers about doing more with less, you're speaking their language. "Methane emissions is lost efficiency. Methane is energy that doesn't get converted to pounds of beef… As the beef industry, we didn't start focusing on that when it became a political issue. We've been focused on that for a long time, trying to make the animals more efficient." says McDonald This reshaping of the methane conversation from primarily a climate problem to be solved for environmental virtue to lost productivity is powerful. The insight is profound. When McDonald sat on a methane roundtable with the oil and gas industry, they described their leaking valves the same way: uncaptured gas is money walking out the door. The economics align across industries. Methane capture isn't virtue—it's profit optimization. But there's an important caveat embedded in this philosophy. McDonald is clear about something critical: the beef industry doesn't need to reach zero methane to make significant impact. Complete elimination isn't the goal—substantial improvement is. This reframes the entire conversation away from perfectionism. As he puts it: "Can we improve it? I think so. Can we make it zero? I doubt it." This conversation explores how the efficiency lens reshapes sustainability from burden to opportunity, and why incremental improvements across the value chain, without demanding perfection, matter far more than seeking impossible silver bullets.

Feed efficiency on pasture: The next frontier with Matt Beck, Texas A&M

The beef industry has spent decades optimizing feed efficiency in one place: the feedlot. Genetics have been selected for finishing performance, cattle are placed on feed at lighter weights and fed to heavier carcasses, and the result is measurable improvement in how much feed converts to pounds of beef. Al Rotz's 50-year life cycle assessment comparing 1972 to 2022 documents this clearly—the industry has made tremendous progress. But this optimization has created a misalignment: the most profitable cattle for the finishing sector are not the most profitable cattle for cow-calf operations. Today we are joined by Matt Beck from Texas A&M, whose research reveals a profound inefficiency hiding in plain sight. For every 100 pounds of additional cow body weight, weaned calf weight increases by only 14 pounds. That extra 100 pounds of cow, however, requires approximately 600 pounds of additional forage annually. Simple math: ranchers are feeding 600 pounds to produce 14 pounds of marketable product. This isn't a visible problem. Ranchers can't see the extra 600 pounds of pasture consumption. But it's there, compounding year after year, driving profitability down precisely when the industry needs it up. Meanwhile, herd sizes have crashed to 1950s levels—not because ranchers want smaller herds, but because drought cycles are becoming more severe and smaller cows are more resilient to them. Matt's most exciting work focuses on methane as a proxy for feed efficiency on pasture. Within the herds he's measured, there's 30% variation in methane emissions among animals producing identical output. And separate research shows that 10% reductions in feed intake are achievable without any loss in productivity. As Matt puts it: "Feed efficiency on pasture is the next great frontier, and with advances in technology, we're becoming more and more able to do that." The challenge isn't scientific. It's economic alignment and infrastructure access for small producers who comprise the majority of the US cow-calf sector. Send us Fan Mail

Why telling people to eat less meat will never work - and what we can do instead with Bruce Friedrich, The Good Food Institute

Meat consumption has risen every single year that the United Nations Food and Agriculture Organization has been measuring. Despite warnings about climate impacts spanning over a century, from carbon and methane's effects to James Hansen's congressional testimony in 1986, to a book called "Diet for a Small Planet" published 52 years ago, global meat production continues its upward trajectory. All available analysis indicates the world will eat at least 50% more meat by 2050. But here's the challenge: human beings struggle with anything requiring self-denial. Energy consumption keeps rising. Miles driven keeps rising. Meat consumption keeps rising. This is not a failure of knowledge or information, it's rooted in human nature itself. Consuming more feels like improvement in quality of life. Today we are joined by Bruce Friedrich, founder and CEO of the Good Food Institute, whose new book "Meat" (meatbook.org) articulates this systems-level thinking. Friedrich offers pragmatic frameworks rather than ideological purity. He recognizes that renewable energy succeeded not by asking people to consume less energy, but by providing better alternatives at competitive prices, enabled by decades of government policy coordinating R&D support, manufacturing incentives, tax credits, and infrastructure investment. He argues that alternative proteins require similar government commitment including: sustained funding for open-source R&D, manufacturing scale-up support, regulatory clarity, and policies that genuinely protect farmer prosperity rather than threatening it. Without government policy as the coordinating force, tribalism, geopolitics, and farmer opposition will likely ensure failure. Friedrich highlights how ranchers and farmers face genuine economic threats that current policy fails to address. Without deliberate government policy protecting their interests, alternative proteins can be seen as an existential threat rather than an opportunity. Ranchers worry about market cannibalization, stranded assets, and unfair competition subsidized by tech investment. These concerns are legitimate and can be addressed by government policy that actively ensures traditional livestock producers share in the opportunities including to where alternative proteins address commodity demand and beef becomes an increasingly valuable luxury product commanding higher prices. The geopolitical dimension cannot be ignored. Eight of the top twenty patent holders in plant-based and cultivated meat over the past five to six years are Chinese companies. China is investing strategically in alternative proteins driven by food security concerns and soft power ambitions, capabilities the West cannot afford to cede. This is not merely about climate or sustainability; it's about technological sovereignty and the future of protein production as a strategic asset. The conversation with Bruce explores how these competing forces, government ambition, farmer/rancher prosperity, technological innovation, and geopolitical competition, can be aligned rather than opposed to accelerate the transition toward sustainable protein production.

Regenerative agriculture with Anastasia Volkova, Regrow Ag

Forty leading global food and agriculture companies recently declared their commitment to regenerative agriculture. This unprecedented industry alignment signals that the sector has moved beyond looking at sustainable farming an aspirational ideal and into investment and scale. Yet challenges remain as adoption of regenerative practices is sliding backward in North America. Satellite imagery processed with AI and biogeochemical modeling reveals that cover cropping and conservation tillage adoption have declined over recent years. In many Midwest states, the losses reach double digits percentage points.This data comes from monitoring 1.5 billion acres globally, representing 52% of global arable land. Simultaneously, farmers are facing a squeeze with rising diesel and fertilizer costs coinciding with weak commodity markets and decreasing government funding. The $3.8 billion investment in climate-smart practices from the Inflation Reduction Act has been partially replaced by a $700 million regenerative pilot program Today we are joined by Anastasia Volkova from Regrow Ag, an early leader and advocate for regenerative agriculture. Regrow has evolved from evangelizing regenerative practices to managing a critical transition to making regenerative agriculture repeatable and scalable across radically different conditions through creative co-investment, alternative funding mechanisms, and regional innovation. Regrow’s framework identifies three distinct market stages: the evangelizing phase focused on building common nomenclature, the investing phase amplified by government dollars and corporate commitments, and the current challenge of making practices repeatable in a constrained funding environment. Her work spans North America, Europe, Latin America, and Asia, revealing how different regions activate different capital sources, from European carbon certification frameworks to Brazilian vertically integrated agro-holdings pioneering methane measurement in livestock. The conversation explores how emerging allies, water markets, and MRV technology innovations could replace disappearing government support without compromising farmer economics or climate outcomes.

Feed efficiency and methane emissions with Ermias Kebreab, UC Davis

The poultry and swine industries have transformed feed efficiency over the past two decades. Through systematic improvement in nutrition, enzyme utilization, and animal genetics, they now produce vastly more protein from fewer resources. The challenge is not simply reducing methane emissions from cows, but reducing methane per unit of milk produced while maintaining farmer profitability and food security. But here's the complexity: feed intake in dairy cattle is difficult to measure in controlled research facilities; in pasture-based systems where 88% of global cattle graze, measurement becomes extraordinarily challenging. Yet without precise data, researchers cannot translate laboratory findings into reliable commercial recommendations. This measurement gap between what science discovers and what farmers can practically implement represents agriculture's critical bottleneck. When you combine this with the variability in dairy systems—roughly 20% natural variation in methane emissions even among genetically similar control animals—the path forward requires nuanced, system-level analysis rather than simple silver bullets. Today we are joined by Ermias Kebeab from UC Davis, whose research demonstrates that genetic selection offers a permanent, cumulative, and heritable pathway to improved feed efficiency. Kebeab's recent work evaluated the EcoFeed index developed by STgenetics, a genomic breeding value tool based on over 10,000 animals—7,623 growing Holstein heifers and 2,538 lactating cows. Results showed that selecting for improved residual feed intake (RFI) reduces lifetime emissions without compromising productivity. A one-standard-deviation improvement in genomic RFI decreased feed consumption by 2.73% and reduced lifetime CO2 equivalent emissions by 2.42% per animal—equivalent to 868 kg CO2e savings per cow. A three-standard-deviation improvement showed even greater potential, reducing feed intake by 8.2% and emissions by 7.31%, while simultaneously lowering feed costs by $199 per female. Ermias's research bridges research discovery with practical implementation across both the Global North and Global South. Kebeab's work on grape pomace byproducts—incorporated at 10-15% of dairy rations—demonstrates milk yield improvements alongside methane intensity reductions, while pre-fermenting almond hulls shows additional potential when economic trade-offs are favorable. Crucially, he emphasizes that the Global South's emissions reduction challenge differs fundamentally from the North. Where dairy systems produce less than 2,000 kg milk annually, the priority must be productivity improvement rather than limiting animal numbers. Rising energy and fertilizer costs disproportionately impact low and middle-income countries, making locally-adapted tropical breeds and resilient farming systems more viable than input-intensive Western genetics.

Artificial Intelligence, the need for reliable data, and where it will have the greatest impacts on agriculture with Aidan Connolly, Agritech Capital

Artificial intelligence is advancing at an astonishing pace—improvements measured in five-thousand-fold increases from week to week according to AI researchers at Singularity University. Yet in agriculture, most farmers remain largely disconnected from these advances, using AI only at the most basic level for administrative tasks like finance, report writing, and form filling. This widening gap threatens to leave the agricultural sector further and further behind as the world accelerates into what might be called the "bullet train moment" of AI adoption. Today we are joined by Aidan Connolly, CEO of Agritech Capital, who has spent the past years advising agricultural organizations on AI readiness. Aidan joins Ash Cloud to discuss how to restructure agricultural businesses for AI-driven decision-making without waiting for others to lead the way. The big challenge is that AI systems can only work with the data available to them. In agriculture, that data is fundamentally flawed. Most farm information is still captured by humans in notebooks, then transcribed into databases. Each step introduces errors, misinterpretation, and gaps that make datasets unsuitable for the sophisticated decision-making AI promises to deliver. Meanwhile, the major AI companies racing forward at incomprehensible speeds won't wait for agriculture to catch up. When you consider that farmers are constantly gathering sensory information through sight, sound, and observation while working in the field, data that never enters any database, the informational chasm becomes even more apparent. Yet animal production systems offer unique opportunities. Dairy cows milked three times daily provide recurring windows to assess milk quality, animal health, fertility, and nutrition. Hens laying eggs daily, pigs weighed multiple times, animals with collars and sensors, these continuous data streams contain vastly more untapped value than the sector has realized. Send us Fan Mail

Building a company that leverages biological complexity to improve livestock productivity with a reduced climate impact - Tom Williams Number 8 Bio

“I’m yet to meet a grazier that doesn’t want a 5-15% feed conversation ratio improvement.” says Tom Williams, CEO of Number 8 Bio. Producers motivated by not losing 10% of their feed to the atmosphere. Enteric methane from livestock represents one of the rare climate challenges where environmental impact aligns with economic opportunity. Methane is a potent greenhouse gas and it also represents wasted nutrition. Approximately 10% of feed energy consumed by ruminants escapes as methane rather than supporting growth or milk production. Few climate solutions offer both emissions reduction and immediate productivity gains for those implementing them. But here's the challenge: the rumen contains billions of microorganisms competing, collaborating, and interacting across complex metabolic pathways. Human knowledge of this biological complexity remains incomplete. Finding molecules that reduce methane without compromising animal health or performance requires casting an extraordinarily wide net. Today we are joined by Tom Williams, founder and CEO of Number 8 Bio, a synthetic biology company developing feed additives to reduce enteric methane emissions. Number 8 Bio's journey demonstrates rapid adaptation to scientific reality. Initially engineering yeast to produce bromoform and seaweed molecules, the team quickly recognized cost barriers for feed additive markets. They pivoted entirely, developing an automated in vitro rumen screening system processing approximately 100 tests weekly. Over several years, they screened thousands of potential products—peptides, enzymes, probiotics, natural extracts, small molecules, and combinations—seeking winners through systematic trial rather than theoretical prediction. The company now focuses on a single organic molecule showing methane reductions and productivity improvements in grazing systems. Initial feedlot trials revealed hydrogen buildup and intake reductions, so Williams followed the science toward pasture-based applications first. The discovery platform—now enhanced with bioreactors predicting live animal productivity outcomes—positions Number 8 Bio to develop additional molecules for different markets and stacking strategies as regulatory pathways allow.

Building resilient agrifood systems across conflict zones and climate stressed regions with Bram Govaerts, CIMMYT

The green revolution resulted in unprecedented improvements in the efficiency and productivity of food production. Recent decades of increasingly globalized free trade has further imporved efficiecies across the supply chain. These improvements that have benefited millions have done so largely at the expense of resiliance and the shock waves of this vulnerability are starting to be felt as fertilizer and energy prices rise. Today I am joined by Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), to his efforts to build resilient agrifood systems across conflict zones and climate-stressed regions. Seventy percent of food consumed in the Gulf states of Bahrain, Kuwait, Qatar, UAE, Saudi Arabia, and Iraq, flows through the Strait of Hormuz. Twenty percent of global nitrogen-based fertilizer exports through this same chokepoint. For decades, global food systems have been optimized for efficiency. Nitrogen fertilizer plants positioned beside oil fields and shipped on demand. This efficiency created abundance and affordability, but at a cost. But here's the challenge: we have become victims of our own success. Pursuit of efficiency without resilience has created dangerous choke points in systems we depend upon for survival. Food system fragility is never just about production disruptions. In Sudan, fertile soils along the Nile could feed the Gulf region, yet conflict has collapsed production systems that previously supplied the area. Across the globe, 60% of countries most affected by climate change also face armed conflict. Food insecurity drives migration and instability that compound the original crisis. CIMMYT's approach operates across three pillars: discovery, system development, and humanitarian response. Current research on biological nitrification inhibition could enable crops to utilize nitrogen fertilizer 30% more efficiently. In conflict zones like Sudan, CIMMYT works alongside internally displaced communities to maintain food production even during active warfare, embedding drought-tolerant seeds and recovery mechanisms directly into humanitarian interventions to reduce the traditional seven-year post-conflict rebuilding timeline.

Leading US beef sustainability with Steve Wooten, Beatty Canyon Ranch

The journey toward sustainable beef production in the United States began before the term "sustainability" entered common usage. Today we are joined by Steve Wooten, a rancher in southeastern Colorado's shortgrass prairie and a founding member of the U.S. Roundtable for Sustainable Beef. Wooten manages Beatty Canyon Ranch in a region receiving 11-14 inches of annual rainfall, where the same perennial grass species documented in Native American archaeological sites continue thriving today under rotational grazing systems. Steve approach to grazing and sustainability changed when he met Alan Savory and learned of his work on holistic management. Eleven years ago, the National Cattlemen's Beef Association established the U.S. Roundtable for Sustainable Beef, bringing together the entire beef supply chain—from cow-calf producers through feedlots, packers, processors, and retailers—alongside civil society organizations and universities. This unprecedented collaboration addressed a critical reality. Only 85% of the nation's cows currently brings a calf to weaning. No major corporation would accept a 15% efficiency loss before year-end, yet the beef industry has operated at this level while simultaneously wrestling with climate concerns and supply chain pressures. Steve's approach integrates multiple data streams, Agriwebb and Pasture Map for grazing tracking, Enriched Ag camera systems capturing images every six seconds for vegetation analysis, and soil carbon sampling. His drought management plan includes trigger dates in March, June, and October for adjusting stocking rates, early weaning protocols, and strategic culling based on meteorological projections. The ranch maintains ungrazed pastures as drought mitigation, ensuring forage reserves for subsequent years while varying grazing timing to provide near-full growing season rest between grazing events—defined in his environment as March through October.

Data driven livestock production for feed efficiency with Andrew Freshwater Clear Creek Pastoral Co.

Feed efficiency remains one of the biggest gray areas and least understood aspects of livestock production. Yet understanding how much grass a cow consumes to produce a calf or a ewe to produce a lamb is critical not only to farmer and ranch profitability, but also to the sustainability of the industry. At 19 cents per kilogram to grow dry matter, inefficiency compounds rapidly. The difference between efficient and inefficient animals can determine whether operations generate profit or struggle to cover overhead costs. Today we are joined by Andrew Freshwater, who has spent over 30 years using data to drive efficient breeding decisions across his sheep and cattle production enterprises in northeastern Victoria. Freshwater's family brought Angus cattle and Romney sheep to Australia in 1849, establishing a multi-generational commitment to livestock genetics. Recent heifer trials demonstrated dramatic efficiency differences between groups run as contemporary cohorts. Through Zoetis genomic testing, Freshwater documented that genetically inferior heifers showed poor feed conversion efficiency and marginal annual returns, while superior genetics in the same management system generated excellent profitability. The lesson is clear: breeding animals is neither pure art nor pure science, but rather a data-informed approach that acknowledges biological complexity while leveraging technology—from genomics to artificial intelligence—to optimize resource utilization across diverse farming systems. Beginning performance recording in 1989 as a teenager, Freshwater has accumulated over 80,000 sheep records representing approximately 3.5 million data points through long-term progeny testing programs. Rather than relying on static estimated breeding values, he has developed proprietary software that runs Monte Carlo simulations incorporating local climate data, grass types, and historical weather patterns to identify the most profitable animals for specific environmental conditions and management systems.

Cow feed efficiency, the greatest area of untapped potential for beef production, with Matt Wilson West Virginia University

Feed efficiency, despite its importance from both an environmental sustainability and farm profitability perspective, remains one of the biggest gray areas and least understood aspects of livestock production. Today we are joined by Matt Wilson from West Virginia University, who has spent his career studying how efficiently cattle convert grass into food. In 2003, Wilson installed the first individual feed intake system at a central U.S. performance test facility. Since 2019, his team has collected daily individual feed intake, water intake, and body weight data on 600-900 animals annually, building machine learning approaches to determine intakes of grazing animals at scale. Wilson's research has revealed dramatic variation in resource efficiency. Two similar bulls in his performance tests gained at identical rates, yet one consumed 50% more feed—approximately 7,000 pounds annually—for no additional performance. This difference represents $600 per animal per year at conservative feed costs. For breeding females in the herd for ten productive years, such inefficiency compounds across their lifetime. Unlike feed additives that only work in formulated rations, genetic improvements in resource utilization are permanent, cumulative, and applicable across both feedlot and grazing systems globally. Of the 90 million beef cattle in the United States, approximately 88% spend their lives grazing on pastures or consuming harvested forages. The remaining 12% are finished in feedlots. Understanding what these grazing animals are actually consuming is critical for accurately assessing the environmental footprint of the beef industry. Grazing animals produce approximately 23 grams of methane per kilogram of dry matter intake compared to 10-13 grams for feedlot cattle—nearly twice as much per kilogram consumed. Since 88% of U.S. cattle and an even higher proportion globally are in pastoral systems where methane intensity is greatest, accurate measurement of grazing intake is essential. Send us Fan Mail

Investing in regenerative agriculture, the food system, and metabolic health with Carter Williams - iSelect Fund

There is a huge amount we can learn from understanding the connections between soil health, food production, and human metabolic health. Over the last 50-60 years, modern agricultural systems have become increasingly reliant on synthetic inputs that boost yields but degrade soil microbiomes and reduce micronutrient density in our food. This degradation contributes to the chronic disease epidemic costing the United States trillions of dollars annually. The impact of regenerative agriculture on both environmental and human health cannot be understated. Healthier soils with robust microbiomes produce crops with superior nutritional profiles—more micronutrients and beneficial phytochemicals that express through the soil-plant-human pathway. When people consume these nutrient-dense foods, they show reduced appetite for processed foods and better metabolic outcomes, though randomized controlled trials remain limited. Today we are joined by Carter Williams from iSelect Fund, a 10-year-old investment firm focused on reducing chronic disease by transforming food systems. Williams coordinates investments across the food value chain—from row crop biologics to novel sweeteners and soil health monitoring. iSelect Fund targets decommoditizing 5-10% of conventional agriculture rather than wholesale transformation, creating price premiums for regenerative producers while stabilizing markets for conventional farmers. The fund prioritizes nutrient density over yield maximization. Williams identifies cognitive load as agriculture's fundamental transformation challenge. Farmers with 20 years of conventional experience face learning entirely new systems. This extends throughout supply chains: CPG companies have infrastructure optimized for current grain varieties; input companies have systems built around synthetic fertilizer. Even willing stakeholders face substantial cognitive and financial investment requirements. The conversation explores modernizing Bureau of Land Management grazing practices. Research showing $200-300 million in upstream regenerative interventions could have prevented $10 billion in European flood insurance losses demonstrates how regenerative livestock management delivers net carbon-positive outcomes while improving rancher economics. Emerging feedback mechanisms accelerate adoption. Companies like Diatious provide data showing how feeding practices affect omega-3/omega-6 ratios, enabling evidence-based practice changes. Companies like Brightseed build in-silico models mapping how growing practices affect phytochemical expression and human metabolism. Williams argues consumer voice—amplified by influencers—now drives change more effectively than the previous decade's farmer-led push. As retailers stock out of cottage cheese due to GLP-1 diet trends rather than label-reading, market dynamics shift faster than Nielsen surveys suggested possible. Send us Fan Mail

Breeding for profitable, efficient, locally adapted and sustainable cattle with Troy Rowan University of Tennessee

Currently beef cattle production faces a profitability challenge driven by rising feed costs and efficiency gaps. For cow-calf operations, particularly where producers operate on forage-based systems, the biggest variable cost is cow feed, yet geneticists lack precise selection tools for measuring and improving forage intake and conversion efficiency. Today we are joined by Troy Rowan from the University of Tennessee, where he investigates economically important traits in beef cattle with particular emphasis on cow efficiency, local adaptation, and genetic approaches to increasing sustainability. His research focuses on developing novel measurement approaches to create practical selection tools for grazing efficiency. The opportunity lies in emerging technologies. While decades of work developed feed efficiency tools for concentrate-fed feedlot environments, these measurements don't translate to grazing systems. Rowan's team explores indicators serving as stand-ins in genetic evaluations, using emissions as metabolic proxies, leveraging precision technologies like AI and computer vision to capture phenotypes previously impractical to measure on large animal groups. Methane and CO2 are important because they are the best indicator of metabolism currently available. Even though they are imperfect metabolism needs to be included to provide an indicator for cow feed costs. Looking forward, epigenetics and other "omics" technologies promise to revolutionize individual animal management. Rather than just predicting genetic potential passed to offspring, these tools could enable phenotypic predictions based on epigenetic marks, gene expression, or metabolomics. A feedlot receiving heterogeneous cattle could place animals in appropriate pens and management protocols based on predicted disease resistance, growth potential, or feed efficiency—filling in the 70% of trait variation that genetics alone doesn't capture. After measuring 10,000-plus animals to develop robust genetic evaluations, the next frontier is translating that knowledge into practical tools that work across the one the billion plus cattle worldwide, from intensive North American operations to pastoral African systems where data recording infrastructure remains the primary bottleneck.

Low cost, locally produced zero emissions nitrogen fertilizer with Frere Byrne PlasmaLeap Technologies

Over the last century our food systems have become increasingly reliant on synthetic nitrogen. This nitrogen fertilizer is mostly made through the energy intensive haber-bosch process in centralized production plants, often located in politically sensitive location, that have a carbon footprint multiple times greater than the aviation industry. Today we are joined by Frere Byrne of PlasmaLeap Technologies who is developing low cost mobile technology to systhesis zero emissions ammonia from air and water. I caught up with Frere to discuss the impact of locally produced nitrogen that is not relaint on fossil feuls and long and centralized supply chains PlasmaLeap's modular chemical plants—called NFix—operate as single 40-foot containerized units producing industrial-grade nitrates and ammonia from air, water, and renewable electricity. These units run autonomously using algorithms, requiring no specialized operators and can be controlled remotely from company desks. For large-scale applications, units stack like batteries to create regional facilities. For smallholder farmers, Plasma Leap has developed miniature versions funded through a Gates Foundation grant, targeting production costs below the lowest commodity urea prices of the past 20-30 years. The technology addresses identical challenges across vastly different farming contexts. Whether a one-hectare subsistence farm in sub-Saharan Africa or a 100,000-hectare cereal operation in Australia, farmers face volatile input prices, intermittent supply chains, and little control over product quality.
