There is no muck and magic behind Carbon Farmer of the Year 2025. Stuart Rogers, Partner at Longmoor Farm Ltd, runs a high-yielding Holstein herd in North Dorset on a Duchy of Cornwall tenancy, and the farm was named Farm Carbon Toolkit's Carbon Farmer of the Year in 2025. Stuart and Rob Purdew, Farm Carbon & Soils Advisor at Farm Carbon Toolkit, joined Andrew and Sarah to explain how a h...

A year on from one of ChewintheCud's most talked-about episodes, Ian Garner, Head of R&D at Antler Bio, returns to take epigenetics from theory into practice on real dairy farms. This time the conversation turns to application. John Walsh, Director at Friars Moor Livestock Health and a dairy farmer running 250 cows through four robots, joins to share how his practice used the ADOPT grant...

Most farmers know lameness is a problem. Far fewer know what it's actually costing them, and the 2026 Stride survey suggests that gap is exactly what's holding the industry back. Andrew and Sarah are joined by Matt Dobbs, Vet & CEO of HerdVision, and Ian Lindsay, Business Development Director at LKL Services Ltd, to unpack the results of the newly released Stride survey on UK dairy m...

Andrew fed England's new fifty-five-page bovine TB strategy into AI and got nine bullet points back — with no way of knowing whether any of them were actually right. So he called Sarah Tomlinson, Lead Veterinary Science Expert at AHDB and the TB Advisory Service (TBAS), instead. Sarah Tomlinson chaired one of the working groups behind the strategy, published in June 2026 with input from over...

This conversation was recorded back in December 2025 and sat on for the best part of a year, with Andrew and Sarah Bolt asked to hold it until the findings could be formally released. The wait was worth it: a GB-wide study of five thousand dairy herds found a quarter tested positive for bovine TB at least once during 2023, including a fifth of herds that were officially TB-free at the time and tra...

Calf nutrition has come a long way since we last covered this topic — and in this episode, we catch up with two of Trouw Nutrition's own experts to find out just how far. Georgina Thomas, Young Animal Feed Technical Sales Manager, and Dr Juliette Wilms, a ruminant researcher who did her PhD on fat inclusion in calf milk replacer, join us to talk through the shift from growth-focused feeding t...

Published abattoir research found over 40% of cull cows had toxic levels of copper in their livers. Pull back to elevated concentrations and Annie Williams, independent mineral nutrition consultant at Mineral Advice Ltd, suggests more than half of UK dairy cows may be above the threshold — potentially suppressing performance in ways that are almost impossible to distinguish from deficiency. In thi...

The transition period is the twenty-one days either side of calving. Get it right and the rest of the lactation follows. Get it wrong and you could spend the next ten months firefighting. To kick off Year Five, we're joined by Vicky Ham, Ruminant Technical Services Manager, Europe for Arm & Hammer Animal Nutrition, to talk about DCAB — what it actually is, why it still strikes fear into p...

Herbal leys can feel like a contradiction: you pay for a carefully chosen seed mix and then it refuses to look the same from month to month. That’s exactly why we wanted a proper, practical conversation about multi-species swards, not the brochure version. Recorded live with a panel of specialists, we dig into what actually happens in the field and how to manage herbal leys for UK dairy systems wh...

If your robot relies on cake to keep cows moving, ask yourself a blunt question: what happens the day the pellet system breaks? That single point of failure is one of the reasons we wanted this conversation, because Kelli Hutchings and Matt Strickland have gone the other way and proven a “cake-free robot” approach can work on a commercial dairy. Kelli is a feed and herd management adviser who foun...

AI is creeping into dairy whether we call it that or not, and most of the noise you hear is either hype or horror stories. So, we brought the conversation into the room with our first live event at the UK Agri-Tech Centre and asked a more useful question: what can artificial intelligence and machine learning genuinely do for a working dairy farm today, and where do the risks begin? We’re joined by...

Sunburn feels like an inconvenience until you connect it to the cancer statistics. Melanoma is the fifth most common cancer in the UK, and Susanna Daniels, CEO of Melanoma Focus, joins us to explain why a “just a mole” mindset is risky, and why early action can be life-saving. We talk plainly about what melanoma is, how UV damage builds up over time, and why noticing a new or changing mole, or som...

Silage isn’t just a crop, it’s a high value asset, and the clamp you store it in can quietly decide how much of it you actually get to feed. We sit down with Jeremy Perkins from SiloStop Agri to talk through what good silage pit design looks like in 2026, from the first site visit to the details that protect forage quality for months. If you’re expanding, switching systems, or simply running out o...

Clover can feel like a gamble until you understand what it’s really doing in the sward and how small management choices decide the outcome. We’re joined by John Spence, Forage Crops Product Manager at Limagrain, to get clear on the practical differences between red clover and white clover, and how to choose the right option for grazing, silage, or a dual-purpose ley on UK dairy farms. We talk thro...

Numbers make people uncomfortable for a reason: they tell the truth. We’re joined by the EDF UK team to unpack European Dairy Farmers and the EDF Congress heading to Chester on 23 to 25 June, including what it is, who it’s for, and why cost of production benchmarking can turn a good idea into a confident decision. We talk through the structure of the three day programme at Chester Racecourse, mixi...

What if your muck heap could hold onto its nitrogen, keep its carbon, and feed soil life the moment it hits the ground? We sit down with Andrew Sincock of Agriton to demystify Bokashi—an anaerobic, lactic-led fermentation of farmyard manure that turns a “waste problem” into a high-value fertiliser strategy. No turning windrows. No mystical inputs. Just weekly microbes on deep bedding, a sensible h...

Forget the headline battles over “cow versus climate.” We dig into how livestock, managed within a circular bioeconomy, can actually reduce risk, recover nutrients, and improve the food we eat. With Professor Michael Lee of Harper Adams University, we connect the dots between soil carbon, methane chemistry, and what ends up on your plate, showing why measuring only gross emissions per kilogram mis...

What if the biggest gains in calf health happen after the first feed? We explore the overlooked power of transition milk — the nutrient- and antibody-rich milkings from days two to four — and how feeding it for 10 days can tilt the odds toward healthier, faster-growing calves. With veterinary surgeon Dr Ryan Davies, we follow a spring block-calving herd in West Wales from a farmer’s observation to...

Fresh grass, quiet robots, and cows that choose their own breakfast. That’s the unexpected picture that emerges when grazing meets automation on modern UK dairy farms. We sit down with Matthew Senior, Farmer & Robot Grazing Consultant and George Dalton, Farmer, who prove robotic milking doesn’t end pasture; it strengthens it, from ABC grazing schedules to leaner labour and sharper decisions. W...

New year, fresh start, better teams. We sit down with Becky Miles from Real Success to map out how UK dairy farms can turn a good hire into a long-term teammate. Not with grand gestures, but with the basics done well: a thoughtful first day, honest safety culture, and the kind of everyday communication that prevents small problems becoming big ones. We unpack a practical onboarding blueprint you c...

What really makes a cow go lame, and why did it take so long to change our minds? We sit down with Professor Jon Huxley—raised on a Welsh dairy, now leading Massey University’s vet school in New Zealand—for a candid tour through research that reshaped mastitis control, lameness prevention, and fresh cow care. Jon shares the story behind teat sealants becoming a cornerstone of selective dry cow the...

Planning grazing by guesswork is costly; planning it with field‑level satellite insight is a game‑changer. We sit down with Chris Knight of Agribot to unpack how AI, radar, and atmosphere forecasting can measure pasture growth, cut labour, and help UK dairy farms make better, faster decisions. Chris shares his journey from space and defence systems into agriculture, and why the most powerful shift...

A farm doesn’t pause for grief, and that’s exactly why a clear succession plan matters. We sit down with Old Mill partners Willem Puddy and Philip Kirkpatrick to unpack the human, legal, and financial knots around passing on a family farm—without tearing the business or the family apart. From the first awkward conversation to the final signatures, we walk through what actually works on real farms....

Ever wish you could read a shed like a story? We walk through CowSignals® with vet consultant Owen Atkinson and coach-trainer Jo Speed, showing how behaviour becomes your best advisory tool. From the CowSignals® Diamond (feed, water, light, air, rest, and space) to the way cows actually see the world, we translate subtle cues into practical changes that raise performance and lower stress. We dig i...

A down cow should never mean panic. We sit down with Dorset tenant farmer James Yeatman and Synergy Farm Health’s research lead, vet Rachel Hayton, to unpack a farmer-built “cow ambulance” that turns a stressful emergency into a calm, repeatable procedure. Born from love for cows and sharpened by hard lessons—and yes, a tough Panorama broadcast—this system pairs a purpose-built, rounded-edge, rubb...
