ChewintheCud Podcast

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 to fund EpiHerd testing across three of its own vets' farms. He walks through what the process actually involves on farm, from blood sampling to waiting on results, and how the trial came about in the first place. Ian explains how Antler Bio's database has grown since last year, now spanning farms across the UK, Ireland, Scandinavia and Canada, and how that extra scale is sharpening the picture on signatures like vitamin D. Sarah and Andrew press both guests on cost, return on investment, and how quickly farmers can expect results back once samples are taken. For John's own herd, an early look at the results already has inflammation, immunity and protein metabolism high on the list to act on, with a full results meeting still to come. It is a candid look at what it actually takes to bring epigenetics onto a working dairy farm, warts and all.

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 mobility. With 173 producers responding on behalf of around 55,000 cows, the data lays out where the industry stands: the average cost of a case of lameness is around £330, yet nearly one in five farmers surveyed believed it was costing them under £100. Matt explains why lameness is a hidden cost in a way mastitis rarely is, and what that means for how seriously it gets taken on farm. Time comes out as the single biggest barrier stopping farms acting, but it's far from the only one. Ian draws a memorable comparison between a modern high-yielding Holstein and a Formula One car: however good the team around her, none of it matters if the tyres, in this case the feet, aren't right. Training, investment, and a lack of clear on-farm responsibility for mobility all feature heavily too, and Matt makes the case for farms appointing someone with the same ownership over mobility that a herd might give a dedicated youngstock manager. Stride is taking these findings on the road this autumn, with confirmed roadshow events in Somerset on Wednesday 14th October and Staffordshire on Wednesday 28th October, both run in association with the National Association of Cattle Foot Trimmers (NACFT - nacft.co.uk).

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 trading with no restrictions in place. The findings come from Rachel Hayton, Research Lead at Synergy Farm Health in the South West of England, recorded alongside Sarah Tomlinson, Lead Veterinary Science Expert at AHDB and the TB Advisory Service (TBAS). Rachel's team used the Enferplex test, a serological blood and milk test made by Enfer Group, applied for the first time at bulk milk level across whole herds, testing around five thousand herds across England, Wales and Scotland three times through 2023, in partnership with Sure Farm Ltd, National Milk Records (NMR), the UK Agri-Tech Centre and SRUC, with funding from Innovate UK. The detail that stood out to Rachel was the overlap: 20% of herds with no restriction history in 2023, believing themselves clear, tested Enferplex positive. Sarah Tomlinson said this confirms what vets have long suspected: that officially TB-free status after two clear skin tests doesn't mean infection-free, and that this is exactly how the disease moves into new herds through trade. Both guests want to see infected animals managed out on a realistic timescale rather than removed immediately, mirroring how Johne's disease is already handled. Since this conversation was recorded, England's bovine TB strategy refresh has been published, setting out exactly this shift.

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 a hundred farmers, vets and scientists — a marked shift from the government-led vision behind the original twenty-five-year eradication strategy in 2013/14. The headline that's grabbed attention is cattle vaccination by 2030, but Sarah Tomlinson was clear it's a smaller part of the strategy than the coverage suggests: field trials are largely complete, and the delay comes down to paperwork, trade rules and getting the DIVA test validated for distinguishing vaccinated from infected animals. Badger culling is ending in favour of vaccination, building on pilots like the one in East Sussex, delivered by local farmers and vets. The change most likely to affect farmers directly is around ancillary testing. Under current rules, a positive animal must be culled within ten working days, triggering movement restrictions and sixty-day testing — which is exactly why farmers haven't wanted more sensitive tests run on their own herds. The strategy proposes letting officially TB-free farmers use these tests without triggering any of that, mirroring how the industry already manages Johne's disease. Herd risk scores will also be shared directly with farmers for the first time, and a new industry-government delivery board will decide priorities and timelines. Sarah Tomlinson named local ownership as the real theme running through the strategy — government can't deliver this alone, and farmers and vets are already good at managing infectious disease without being told how. She also shared a message from a farmer she'd supported through TBAS that made the human cost of TB breakdowns impossible to ignore alongside the policy detail. The strategy also references Enferplex, the bulk milk test at the centre of a major new GB-wide study — hear the full findings in this week's other episode, Revolutionising TB Testing: Is Bulk Milk the Key?

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 to what they call resilience-focused nutrition. We get into why eight litres a day is now considered moderate rather than generous, what a calf would actually drink if left on its dam, and why feeding more only works if you're feeding the right thing. The heart of the conversation is fat — specifically the short and medium-chain fatty acids that occur naturally in whole milk but have historically been almost impossible to replicate in a calf milk replacer. Juliette explains the science behind restoring these, and why the payoff shows up most clearly in gut and respiratory health, not just growth rates. We also get into the real cost of scours and pneumonia in the calf shed, what Trouw's own research trial found when comparing four litres against eight, and why getting the fat-to-lactose balance right matters just as much as how much you're feeding. We round things out with a plain-English explanation of osmolality, why whole milk and calf milk replacer each have their place depending on your situation, and where Trouw's research is heading next — including some early findings on dairy beef calves that could reshape how a growing share of the industry rears its animals. As always, it comes back to the basics: get your colostrum, hygiene, and stockmanship right first, then use nutrition to build calves that can cope with whatever a real working farm throws at them. This episode was recorded in July 2026, and all information was correct at the time of recording.

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 this conversation, we examine why copper excess is a far more widespread problem than most farmers and advisers currently recognise, and what can realistically be done about it. The conversation covers the limits of blood testing, why liver biopsy is the only reliable measure of copper status, and how to conduct a proper mineral audit that accounts for every copper input across an animal's lifetime — including concentrates, forages, water, injectables, drenches, and boluses. Annie explains the role of antagonists, why grass-based systems carry higher risk than housed TMR, what palm kernel extract means for formulation, and how copper accumulated in the calf shed follows a heifer right into the milking herd. The area where knowledge is thinnest — and where Annie expects the most significant development — is the pre-ruminant calf. Adult cattle absorb less than 10% of dietary copper; a pre-ruminant calf bypasses the rumen entirely and absorbs somewhere between 60 and 80%. Current guidance recommends 5 mg/kg dry matter in calf milk replacer, five times what whole milk naturally contains, and nobody is entirely sure where that figure originated. Research underway at Harper Adams, led by PhD student Amy Marsh, is trying to establish what the correct formulation targets should be.

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 people who should know better, and why the research keeps pointing in the same direction. The work goes back to Dr Elliot Block in the mid-1980s and is reinforced by meta-analyses from J.E.P. Santos: cows fed a negative DCAB diet calve with better calcium status, suffer fewer transition diseases, and eat more dry matter post-calving. The evidence is there. The question is why more people aren't using it. We cover the basics of acidification and how urine pH testing tells you whether cows are actually where they need to be — and why there is no such thing as a partial DCAB diet. You are either acidified or you are not. On the practical side we talk forage mineral analysis, straw potassium surprises in drought years, protein source selection, palatability, mixing, and why consistency is everything. We also cover what happens post-calving, stocking density, feed space, and why cows need to come off the negative DCAB ration the moment they calve. We also get into newer thinking on inflammation — the emerging evidence that hypocalcaemia may be less about calcium deficiency and more about an activated immune system demanding calcium and glucose at the expense of everything else. Studies suggest close to sixty per cent of cows at calving show inflammation with no clinical signs whatsoever. Managing that inflammatory load is not a separate conversation from transition nutrition. It is the same conversation. This episode was recorded in June 2026, and all information was correct at the time of recording.

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 when the weather turns extreme and the rotation plan stops behaving. We start with trial insights from Dr Jo Matthews on how different species contribute across the season, why plantain and chicory peak at different times, and what resilience really means when drought hits. We also get into the detail that gets missed: tannins from birdsfoot trefoil, mineral profiles in individual species, and why “more species” only helps if something can persist under your grazing or cutting pressure. If you care about soil health, drought resilience, livestock health and cutting purchased fertiliser, this is the kind of data-led context that helps you choose with confidence. Then Becci Shrimpton brings the agronomy reality check: soil testing before seed choice, pH and P and K targets, seedbed and drilling depth for tiny seeds, and why weed control is mostly a pre-sowing job because broadleaf sprays can wipe out the mix. Ben Richards rounds it out with a farmer’s view from Cornwall, running a 100% forage, organic, once a day milking herd on herbal leys, explaining grazing covers, residuals, rotation length and why he avoids hammering the sward. This podcast was recorded in front of an audience, and once our guests had made their initial presentations, they then took questions directly from those in attendance, asking real questions relevant to farms today! This was recorded in February 2026, and all information was correct at the time of recording.

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 found herself deep in the world of DeLaval VMS after helping launch large robotic sites across North America. Matt is a fourth-generation dairy farmer in Merced, California, running eight robots milking around 500 cows in a guided flow barn, alongside a larger conventional herd. Together, they explain why feeding concentrate in the robot can be a costly habit, how cows learn expectations fast, and why cow behaviour and facility design matter as much as any dashboard. We get practical about the change process: starting new heifers with no pellets, weaning conditioned cows slowly, and building a shortlist of KPIs that protect you from rumours and knee-jerk decisions. We talk visits, fetch lists, box time, incompletes, milk components, butterfat, and the commercial headline of income over feed costs. You will also hear the limitations, including why guided or modified guided flow is currently the best fit and why forage quality and TMR palatability are non-negotiable. If you manage robotic milking, advise UK dairy farms, or are planning a robot investment, this is a rare chance to rethink concentrate strategy with real numbers and honest caveats.

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 Chris Knight from Agribot, Ian Garner from Antler Bio, and Mike Jones from the UK Agri-Tech Centre. Chris pulls the curtain back on the history of AI, why the core ideas are older than most people think, and why large language models feel revolutionary mainly because we can talk to them. Ian shares how AI can speed up development and knowledge work without becoming a source of truth, including building science-grounded recommendations with expert validation to avoid confident nonsense and hallucinated references. Mike brings it back to the coalface with tools being tested on real farms: earlier lameness detection, consistent body condition scoring, sensors that flag cows needing attention, methane monitoring, and even birdsong analysis for biodiversity benchmarking. Along the way we tackle accuracy versus consistency, predictive tools, data integration across too many apps, trust and privacy, and the awkward question of who really owns farm data.

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 something that simply looks odd is the moment to contact your GP. We also bring it back to farm life. Outdoor work in agriculture and horticulture means higher exposure, and Susanna shares survey findings showing sunburn is far more common in the sector than in the general public. We dig into the culture piece too, especially why men often skip sunscreen, and how employers can treat sun protection as a health and safety control by providing sunscreen and making reapplication normal on busy days. You’ll come away with practical guidance you can use straight away: the expanded Slip Slop Slap message (plus shade and sunglasses), how to use the UV index (protect when it is 3 or above), what “broad spectrum” really means, and what to look for on the bottle (SPF 30+ and a high UVA star rating). We also tackle vitamin D without turning sun exposure into a false excuse, and we finish with a clear reminder that nearly nine in ten melanomas are preventable.

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 of space, this conversation helps you think clearly about layout, access for modern machinery, and how to future proof capacity without creating an unmanageable feed face. We get practical about the rules as well. We break down SAFO regulations in England and what inspectors are looking for around silage effluent and leachate containment, then compare that with Welsh COPR requirements, including why tarmac floors can be preferred and how features like inspection chambers support compliance. Along the way we discuss earth-bank options, vertical wall systems, drainage falls, and why planning permission and build timelines matter more than most of us want to admit when second cut is looming. We also zoom into the small stuff that makes a big difference: oxygen barrier film, sidewall film, safer clamp handrails, and cleaner weighting options that replace the misery of tyres. The takeaway is simple: invest once, do it properly, and treat homegrown forage like the foundation of margin and efficiency it really is.

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 through the big paybacks farmers actually care about: higher home-grown protein, better digestibility, and nitrogen fixation that can cut fertiliser use when prices spike or supply tightens. John explains why clover often carries summer growth when grasses dip, how deep rooting links to drought tolerance and soil structure, and where clover fits alongside SFI options and multi-species or herbal leys. Then we get into the detail that makes clover work on farm: white clover leaf sizes and why blends matter, red clover longevity expectations, sowing windows based on soil temperature, seedbed and sowing depth, and the realities of overseeding. We also cover bloat risk sensibly, cutting date decisions for quality versus yield, why clover silage can benefit from an additive, and what to do when NIR forage analysis struggles with clover-heavy or mixed swards.

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, mixing plenary sessions, targeted workshops and tightly run farm visits in one of the UK’s most concentrated dairy regions. The theme “New Challenges, New Opportunities” gives us room to explore what sustainable dairy farming looks like in practice, from the technological revolution of robots, sensors, machine vision and artificial intelligence, to sustainability from the ground up through soil management, forage quality and smarter nutrient use. You’ll also hear why EDF’s approach stands out: farm visits anchored by real performance figures, workshops that let farmers compare key KPIs like labour efficiency, and the kind of networking that sends you home with at least one “nugget” worth implementing. If you’ve never come across EDF before, this is your route into a Europe wide conversation about efficiency, resilience and adding value in a volatile milk market.

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 handle on carbon-to-nitrogen ratios, and a sheet to finish the job. Andrew takes us from first principles to field results. We compare aerobic composting, anaerobic digestion, and fermentation, and unpack why carbon and nitrogen losses plummet when oxygen is kept out. If you understand silage, you already understand the logic: inoculate, exclude air, and let biology do the heavy lifting. We connect the dots between rumen microbes and soil microbes, showing how pre-digested, fermented FYM accelerates the soil food web, enabling practical moves like applying around eight tonnes per hectare between silage cuts without messy residue at harvest. This is as practical as it gets. You’ll hear how to apply mixed microbes on bedding once a week, balance materials from straw to woodchip to poultry manure, and decide when to muck out, sheet, and spread. We dig into economics—independent comparisons reported about £15 per treated tonne more NPK against roughly £1 per tonne in treatment cost—and talk through where shortcuts still work and where they don’t. We also address slurry and lime: where microbes help, where acidification looks tempting but risky for soil biology, and why better management beats heavy-handed fixes. If you’ve written off biological farming as “muck and magic,” this conversation gives you the science and the steps to test it on your own ground. Start small, measure your FYM like you measure your forage, and let the results guide your next move. If it’s simple to explain and easy to fit into chores, you’re more likely to stick with it—and your soils, crops and margins will follow. Enjoyed this deep dive?

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 misses the true picture of sustainable dairy and beef. We start by reframing circular farming: crops generate non‑edible biomass and the food industry creates co‑products; ruminants turn those streams into milk and meat while producing organic manures that, with new stripping and separation technologies, return nitrogen and phosphorus to the fields that need them. That reduces dependence on mined phosphate and fossil‑fuel fertiliser and strengthens soil health and biodiversity. We also unpack the geopolitics of nutrients, from export controls to the hidden carbon cost of extraction, and why better manure management is both an agronomy win and a climate hedge. Then we get precise about methane. Biogenic methane sits in a short‑lived natural cycle; thermogenic methane from fossil sources adds new carbon to the atmosphere. Agriculture must cut emissions, and can, through genetics, feed, and efficiency. But farms are too often judged on gross emissions while their removals through soils, hedgerows, and trees are booked elsewhere. Case studies from Ireland show how net accounting can reveal major improvements and, in some systems, net‑zero performance. The takeaway is clear: measure net, reward verified removals, and avoid a carbon‑only lens that ignores biodiversity, water, and rural livelihoods. Finally, we get practical about what to eat. We don’t eat by the kilogram; we eat for nutrients. Animal‑source foods provide highly bioavailable protein and hard‑to‑get micronutrients, while plant foods supply the fibre most of us lack. Ultra‑processed “plant” proteins often strip out that fibre. A smarter plate is plant‑rich, fibre‑dense, and includes modest amounts of unprocessed dairy and meat. Using more of the carcass, including offal, cuts waste and boosts nutrient density.

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 a structured study, complete with daily passive immunity testing and twice-daily Brix checks on pooled, pasteurised fresh cow milk. We start with the fundamentals: dialling in colostrum quality, quantity, timing, cleanliness, and stress to hit excellent passive transfer. Then we move beyond day one. Ryan breaks down how calving density drives pool quality, why Brix can fluctuate from bulk-tank levels to true transition milk, and the practical choice every farm faces — maintain quality for the youngest calves or dilute to stretch days. The data make the case: calves receiving higher-quality transition milk grew faster to weaning, and those with low serum IgG at 24–48 hours saw a reduced mortality risk when the quality was strong. It’s a clear demonstration of local gut protection from antibodies and the extra lift from proteins, fats, growth factors, lactoferrin, and prebiotics. We also address the risks and realities: pooling can spread pathogens, pasteurisation has limits for Johne’s and TB, and over-heating destroys the very bioactives we need. The solution is disciplined herd health plans, careful cow selection for the pool, and routine measurement. Expect straight talk on Brix targets, when to prioritise younger calves, and why prevention beats treatment when disease pressure climbs later in the block. The early signals are promising for beef finishing times and future heifer performance, with full productivity and longevity data to come. If you’re aiming to reduce antibiotics, protect staff morale, and improve sustainability without adding complexity, this is a practical blueprint: test, pool, pasteurise, protect quality, and feed transition milk for 10 days.

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. We unpack why a shift from spring to autumn block calving can fit dry summers, wet winters, and evolving milk contracts. The conversation follows the practical steps: planning lanes and gates, sizing paddocks, sticking to entry covers around 2,800–3,000 and residuals at 1,500–1,600, and letting the grazeway gate cue movement every eight hours. The cows’ driver isn’t sweets in the stall; it’s fresh pasture on the other side of the robot. Average visits hover around two per day, robots stay free for heifers and fresh cows, and the yard stops feeling like a twice-daily stampede. We also dive into self-feed silage for autumn herds: building a wide pad, layering grass cuts, topping with maize and rape meal, and training cows to eat over a wire without waste. It’s not no work, it’s different work—periodic unsheeting, tidy faces, good wire geometry—and it cuts reliance on mixers and daily diesel. On the data front, collars and robot software deliver fast, focused insight: daily milk records, rumination, activity, and health and heat lists that you act on with judgement, not panic. Many alerts self-resolve; late-lactation cows don’t need three milkings; breeding gets simpler when the gate auto-segregates cows for AI. The real win is balance. Yields rise with targeted cake, antibiotics fall, and days become more flexible. Visitors see cows roaming by choice, a powerful story for animal welfare and transparency. If you’ve ever wondered whether robots and grazing can coexist, this is a clear, practical roadmap that shows how to get more milk from grass, protect soil and lanes, and reclaim your time.

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 can copy tomorrow—10 a.m. start, warm welcome, terms and conditions on the table, health and safety brief, PPE issued, WhatsApp groups explained, and a mentor assigned. Becky introduces the accountability ladder to shift behaviour from blame and excuses to ownership and solutions, and explains why leaders must provide time, tools, skills, and knowledge before they demand results. We dig into vision, mission, and values, turning them from corporate wallpaper into simple, lived behaviours around animal handling, safety, and respect. From there, we get specific: weekly breakfast huddles with KPIs, sharing milk tickets and cell count trends, giving credit when it’s due, and handling conflict with cool heads and open questions. We challenge the myth that pay is the main lever, showing how flexible rotas, visible leadership, and small rituals—like a team breakfast after milk recording—carry more weight. Training stays central, with smart ways to protect investment, because the real risk is an untrained person who stays. We also tackle facilities and first impressions; a bright, tidy parlour and fit-for-purpose kit speak louder than any slogan. If you’re aiming to reduce churn, lift morale, and get more done with less drama, this conversation offers concrete steps and language you can use with your team today.

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 therapy, showing how solid trials helped cut antibiotic use without compromising udder health. We then tackle the big pivot in lameness thinking: moving beyond the old acidosis-laminitis narrative to the digital cushion, body condition, and the brutal role concrete plays in claw horn lesions. The result is a practical blueprint—protect condition around calving, improve surfaces and cow flow, and trim with function in mind. Treatment gets equal airtime. Randomised trials demonstrate why NSAIDs matter for lame cows, reducing inflammation and pain to speed recovery. Extend that approach to fresh heifers and the benefits often reach into second lactation. From there, we zoom out: are mastitis, metritis, ketosis, and lameness different faces of the same early lactation inflammatory stress? If the transition cow is the most fragile athlete on the farm, then feed space, comfort, calm routines, and energy balance are one system, not a checklist. We also compare UK housed systems with New Zealand’s pasture-first dairying: longer walks on laneways, fewer hours on concrete, and lower lameness, but rising buffer feeding, new shelters, and tough conversations on nutrient leaching. Along the way, John explains how Massey’s hands-on facilities and the Kiwi “give it a go” mindset produce work-ready vets who can turn evidence into action. Listen for clear, usable insights on mastitis prevention, lameness treatment, digital cushion management, underfoot design, and the transition period. If you want fewer sore feet, fewer sick fresh cows, and more sustainable milk, this conversation pulls the science onto the yard.
