Happy Horse Nutrition

If you are spending money on joint supplements for your horse, or wondering whether that corticosteroid injection is really helping, this episode is essential listening.Dr. Nerida is joined by Renee Harbowy and Dr. Brian Nielsen from Michigan State University, two of the leading researchers in equine joint and bone health, for an honest, science-based conversation about what actually keeps horses sound for life.Renee shares the findings from her recently published research study examining whether glucosamine and chondroitin supplements improve lameness in horses with osteoarthritis, and what the results mean for every horse owner standing in front of a wall of joint supplements at the feed store.From there, the conversation covers equine joint health from the ground up.In this episode you’ll learn:What osteoarthritis actually does to joint tissue and why understanding this changes how you manage itWhy movement is non-negotiable for cartilage health, and what happens to joints when horses are stalledThe research on pastured versus stalled horses and what it means for how you manage your horse day to dayWhy nutrition from conception onwards is the foundation of lifetime joint soundnessThe trace minerals most commonly deficient in horse diets and why deficiencies during development cause problems that show up years laterDr Brian’s research on bone strength and the surprisingly small amount of exercise needed to maintain itThe five things Renee considers most important for long-term joint healthThe truth about corticosteroid injections; what they actually do, and the risk of masking pain in performance horsesEarly warning signs that your horse’s joints may be struggling before obvious lameness appearsPractical, actionable strategies for joint health regardless of your horse’s age, breed, or living situationWhether you have a young horse you are bringing up right, a performance horse in hard work, or an older horse starting to show their age, this conversation will change how you think about joint health and what you can actually do to help your horses have a long, sound, happy life!🧪 Renee's full research paper can be found here (and it is well worth the read, beautifully written and a brilliant piece of science!): https://pmc.ncbi.nlm.nih.gov/articles/PMC13113781/ 🌟 If this episode helps you look at joint health a little differently, please follow the podcast so you don’t miss what’s coming next.💛 And we'd love you to share it with a horse friend, especially someone with a young horse, an older horse, or a horse already struggling with joint issues. These are the conversations that can genuinely change how we manage horses for the better.📲 And if you want help getting the nutrition side right, download the MyHappy.Horse app. It’s like having a practical, science-based equine nutritionist in your pocket, helping you feed with more confidence and less second-guessing.⁠https://apps.apple.com/au/app/myhappy-horse/id6633422324⁠

There is no time in horse nutrition where you need both art AND science more than when you are feeding a weanling.These funny, curious, chaotic little creatures are walking a tightrope every single day... growing fast enough to reach their genetic potential, but not so fast that they end up with bone or joint disease. Get it wrong, and you are looking at OCD, contracted tendons, physitis, stunted growth, and a horse that never becomes what it was born to be. Get it right, and you lay the foundation for a lifetime of health and soundness.In this episode, professional equine nutritionist Dr. Nerida draws on 25 years of experience and thousands of weanlings from Australian thoroughbred studs to Japan’s biggest breeding farms, to walk you through exactly what your weanling needs and why.You’ll learn:How to manage weanling growth rate and body condition score to reduce developmental orthopaedic disease riskWhy energy intake is one of the most important factors in weanling joint healthHow pasture quality, climate, and compensatory growth affect your weanling’s diet... and how to stay two steps aheadWhy protein quality (not just quantity) is critical for muscle and bone development in young horsesThe fine details about calcium, phosphorus, and trace minerals and why almost every pasture Nerida has tested falls shortThree practical feeding strategies for weanlings depending on your situation; andWhy a balanced diet... NOT a restricted one... gives your weanling the best shot at lifetime soundnessWhether you have one very special homebred foal or paddocks full of youngsters, this episode gives you the knowledge and the confidence to feed your weanlings well.📱 If you’d like help balancing your  weanlings' diet, download the MyHappy.Horse app on the Apple App Store and start building a diet you can feel confident about. https://apps.apple.com/au/app/myhappy-horse/id6633422324 💖 And if this episode helped you, please share it with a horsey friend (especially the one currently with a pregnant mare 😅)

In this replay episode, we are bringing back Dr Nerida’s chat with Professor Brian Nielsen on bone health in horses, because the ideas in this conversation have huge implications for soundness, durability, performance and long-term welfare.If you have ever been told that long, slow work builds strong bone, or that the safest path is always to wait until horses are skeletally mature before exposing them to speed, this episode may really make you stop and think.Dr Brian explains how bone actually adapts to exercise, why turnout and even very small amounts of high-speed work matter so much, how confinement can reduce bone mass, and why this is such an important issue for young horses in particular. It is a fascinating conversation that challenges some deeply held beliefs in horse management and racing, while also being incredibly practical.This was one of the standout episodes from the early days of the podcast, and now that many more of you are listening, it feels like the right time to bring it back.If you care about raising, training or managing horses for long-term soundness, this episode is well worth your time 🌟 🧪Find the full scientific review here: https://www.mdpi.com/2076-2615/13/5/789 💛 If you’re looking for more practical help with nutrition and managing your horse, have a look at MyHappy.Horse, our app designed to help horse owners make more confident feeding decisions. https://www.myhappy.horse

Is canola oil really as bad as people say… or has it simply been one of the most unfairly demonised ingredients in horse nutrition?In this episode of the Happy Horse Nutrition Podcast, Dr Nerida is joined by Orla for a fascinating and surprisingly fun deep dive into the real story behind canola oil. They unpack where the wild claims came from, including the viral email that helped fuel decades of fear, and separate old rapeseed oil facts from modern canola oil fiction.Dr Nerida and Orla talk about erucic acid, GMO confusion, the strange myths linking canola to everything from blindness to mad cow disease, and why scary misinformation can stick so powerfully in people’s minds. They also bring it back to what really matters for horse owners: where canola oil fits in equine diets, how its omega-3 and omega-6 profile compares with other oils, and why it can actually be a very useful and appropriate choice in the right situation.If you have ever wondered whether canola oil is truly harmful, or whether this is another nutrition myth that has taken on a life of its own, this episode is for you.Here is the full, crazy backstory canola oil email in case you’d like to read it: https://www.snopes.com/fact-check/canola-oil/If you are tired of guessing and would love a clearer picture of your own horse’s diet, come and see what we do at MyHappy.Horse.

Orla is back in the Q&A seat… and she’s come armed 😅 In this episode of the Happy Horse Nutrition Podcast, Orla has curated a stack of listener questions (and kept Dr Nerida completely in the dark), so it’s a fast-paced, practical chat that bounces from industry ethics to real-life feeding decisions you’ll recognise instantly.We start with a big one: what actually makes someone a “nutritionist” in the horse world, and why that label can be meaningful… or totally meaningless. Nerida unpacks the difference between qualifications, experience, and the uncomfortable reality of “armchair experts” giving confident advice that can cost horses their health.From there, the conversation gets wonderfully hearty:Raw/cracked grains (especially corn): why this can be a hindgut wrecking ball when fed inappropriately, and what “gold standard” feeding looks like when welfare and performance matter.Hair analysis: when it might be useful (think toxins/heavy metals), why it often isn’t reliable for everyday nutrition decisions, and why diet analysis beats guessing, every time.Metabolic ponies + ulcers: why so many EMS “good doers” end up with serious gastric ulcers, and the management patterns that quietly set them up to fail (hello, long hours without forage).Orphan foals: Nerida shares a practical, “doable in the real world” approach to feeding orphan foals, including a simple milk-mixing recipe and how frequency of feeds can make or break a foal’s gut. If you’ve ever felt overwhelmed by conflicting advice, marketing masquerading as science, or you just want a clearer path to feeding with confidence—this one’s for you. 🐴💛Here is the link to the 'How to feed an orphan foal' article from Dr Nerida: https://www.myhappy.horse/blog-posts/rearing-the-orphan-foal  Want to analyse your horse’s diet properly (without the stress)? Download MyHappy.Horse here: https://apps.apple.com/app/myhappy-horse/id6633422324And if you enjoyed the Q&A chaos with Orla 🤪🧡, we'd be so grateful if you'd leave a quick review on Apple or Spotify, it helps other horse owners find the show 🙏🏼 

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida is joined by Joanna Lepiarczyk from Horses Explained for a fascinating and deeply important conversation about horse mental health, equine behaviour, and the role that nutrition and feeding systems play in shaping a horse’s emotional wellbeing.We explore why behaviour is so often a form of communication, why a quiet compliant horse is not always a happy horse, and how chronic stress can affect a horse far more profoundly than many owners realise. Joanna shares her perspective on horse depression, the emotional cost of restricted forage and limited choice, and why the foundations of a good horse life are surprisingly simple: forage, freedom, and friends.We also talk about the importance of constant access to something to chew, forage variety, movement, predictability, agency, and why these are not “nice extras” but core building blocks for a horse’s physical, mental, and emotional wellbeing.This is a thoughtful, compassionate, and at times confronting conversation that will encourage you to look beyond behaviour and think more deeply about how your horse is actually experiencing daily life.If you care about horse welfare, equine mental and emotional health, feeding management, and giving horses the conditions they need to truly thrive, this is an episode you won’t want to miss. 🐴 🌟 Joanna Lepiarczyk is an equine behaviour expert, classical riding coach, and the author of Understanding Horse Depression, with a focus on equine mental health, horse personality, and helping riders understand horses more deeply.  🧡 You can connect with Joanna at https://www.horsesexplained.com and follow Joanna’s work @horsesexplained Joanna’s favourite book is ‘Training Showjumpers’ by Anthony Paalman 📲 To find out more about what we do here at MyHappy.Horse you can go to https://www.myhappy.horse or download the app (7-day free trial availabile): https://apps.apple.com/app/myhappy-horse/id6633422324

Grains are one of those ingredients that get demonised in the horse world… or are fed completely on autopilot. And neither is an ideal situation.In this episode of the Happy Horse Nutrition Podcast, Dr Nerida digs deep into her PhD research and explains why grain itself isn’t bad — it’s more like a power tool. Used well, in the right horse, grains are incredibly useful. Used carelessly (wrong type, wrong form, wrong amount), and grains can rapidly destroy hindgut health… and in severe cases, even cause death.In this episode, you’ll learn:Why the real issue is starch, and why starch must be digested in the small intestine (and not dumped into the hindgut)How uncooked/poorly processed grains can drive hindgut acidosis, microbial dysbiosis, leaky gut, inflammation, behaviour changes, colic and laminitis riskWhy cracking, grinding, and soaking don’t solve the core problem What “cooked grain” actually means and why extrusion tends to win on digestibilityWhere oats fit and why uncooked corn/maize is a hard no!Which horses should avoid grain altogether (including insulin dysregulation/PPID/EMS, PSSM/tying up) vs when grain is genuinely helpful (including thoroughbred racehorses, high-performance athletes)Grans are incredibly useful ingredients IF you know how to safely feed them. This episode helps you understand why grains are often unsafe AND how to make them safe to feed in appropriate situations.📲 Want to see how your current feeding program stacks up for gut health?

Track systems (perimeter grazing systems) can look deceptively simple… but when they’re designed well, they deliver things horses are wired for: friends, freedom, and forage… with extra movement built in. In this episode, Dr Nerida is joined by the wonderful Dr Katherine Goldberg (DVM, LCSW), a veterinarian and clinical social worker,  to unpack what “species-appropriate husbandry” actually means in the real world, and why track systems aren’t just a “weight loss tool” for good doers, but a way we can help horses to live in a way that truly honours their needs. Dr Nerida and Dr Katherine talk about the concept of horses being behaviourally starving even when obese, the two welfare rules Katherine won’t budge on, and how meeting these basic needs changes behaviour, safety, gut health, and the horse–human relationship.You’ll also get practical, immediately usable setup guidance on track width, why varying widths can create natural movement patterns, and how separating resources (water, hay, shelter) encourages that nomadic, forage-and-walk lifestyle horses evolved for. Dr Katherine is the most beautiful human, driven by the desire to help us all create better, happier, more species-appropriate lives for our equine friends in which our horse-human relationships and horse goals, whatever they may be, can flourish! If you’d like to get in contact with Dr Katherine, you can find her at [email protected] And if you would like more information on what we do here at MyHappy.Horse you can find us over at https://www.myhappy.horse Thanks so much for being here 💖💛

Free faecal water (also called free fecal liquid) is one of those horse problems that looks “not that bad” on paper… but how 'bad' is it? 🐴💦In this episode of the Happy Horse Nutrition Podcast, Dr Nerida unpacks potential reasons why FFW is suddenly being talked about everywhere, from first hearing it at a conference in Dijon (2016) to seeing it dominate conversations at AAEP Denver (2025). And yes… she asks the uncomfortable question: is this another disease of modern management impacting an ancient gut?You’ll learn:What FFW is Why it’s likely multifactorial (forage changes, fibre variety, grain load & digestibility, sand irritation, ulcers, nitrates…)The practical “low-hanging fruit” steps to try first, in a logical order to help resolve FFWWhy microbiome research can be misleading when it’s only measured at broad levels (and why species-level testing may be the next big breakthrough); andWhen to loop in your vet (sand assessment, ulcer scoping, more advanced options like faecal transplant)If you’re dealing with FFW, this is your calm, evidence-informed roadmap to helping your horse.As always, please follow the podcast so more horse owners can find this, and if it helped, share it with a friend (or your whole agistment chat 😉). 💛💖 Want to see how your current feeding program stacks up for gut health?

What happens when your horses live on mostly straw for 10 days… and one of them decides to protest with full-blown diarrhoea? 😅 In this Q&A-style catch-up, Dr Nerida and Orla unpack a very relatable “whoops” moment and use it to teach one of the most overlooked fundamentals in horse gut health: fibre diversity.They break down why straw is a very different beast to hay (hello, lignin), why some horses cope while others fall apart, and why “just add a product” isn’t always the smartest first move. From there, the conversation goes behind the scenes of the feed industry, mixed-species feed mills, the very real risk of ionophore contamination, and how to ask the right questions of manufacturers. Then it gets nerdy (in the best way) with least-cost vs set recipes, why crude protein can be misleading, and the lysine + leucine muscle-building “bricklayer and bricks” analogy you’ll love.In this episode you’ll learn:Why restricting forage to one source can trigger loose manure/free faecal water in some horsesWhy gut “fixes in 3 hours” are usually not how physiology works (and when electrolytes can confuse the picture)How to read a feed label to spot vague “least-cost” ingredient wordingWhy protein quality matters (especially for young horses, broodmares, and performance horses) 🐴💛 Want help making sense of your horse’s diet?

Feeding an Off The Track (OTT) in the first 12 months can be a worry inducing juggle… appetite, behaviour, ulcers and those classic “why won’t you hold weight?” situations. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida shares her practical approach to feeding OTTs in their first year off the track so they can settle, digest fibre properly, and become easier to keep long-term.Nerida explains why many OTTs arrive with gut health issues. Racing routines and high-energy feeds can increase gastric ulcer occurence and shift the hindgut microbiome away from the good fibre-fermenting microbes. And when the gut isn’t right, it often shows up as a fussy appetite, tricky behaviour, and slow weight gain in OTTs. The episode breaks the first year into two phases: months 1–6 focus on gut rehab with forage first, fibre diversity and balancing vitamins and minerals the focus; then months 6–12 shift to weight and muscle development, with one big caution… weight gain diets change behaviour, sometimes dramatically.Listen to discover how to feed your OTT in the first 12 months off the track for brilliant results… setting your OTT up for a lifetime of health, happiness, calm behaviour and brilliant performance.🌟 Follow the Happy Horse Nutrition Podcast so you don’t miss the upcoming episode unpacking Allay’s microbiome data with Dr Belinda Chapman. 💖 If this helped, a quick rating on Spotify or Apple Podcasts helps other OTT owners find the show. 📱 Want to check your OTT’s diet is balanced while you adjust feed for behaviour and condition?

NSC is one of those three-letter acronyms that pops up on feed bags and hay reports… and consistently manages to confuse even the most dedicated horse owners. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida McGilchrist unpacks Non-Structural Carbohydrates (NSC) in a practical, horse-owner-friendly way.This episode looks at what NSC actually is (starch + water soluble carbohydrates; WSC), how it relates to WSC, whether we should be using WSC or ESC to calculate NSC (see, it gets confusing!), and why that 'fructan piece' matters for both laminitis risk and the hindgut microbiome.You’ll learn why NSC is everywhere in hay, pasture and feeds, and why it’s levels can fluctuate so dramatically, depending on plant type, time of day, climate, temperature, drought stress, and even soil fertility. Nerida shares real-world examples (including from her own horses) to explain what happens when NSC is too high. Problems can include crazy high insulin levels, laminitis, colic, tooth decay and microbial dysbiosis. And she explores why “not enough NSC” can also be a problem in performance horses where energy intake, palatability, and gut function matter.If you’re feeding a pony with insulin dysregulation, a horse with PPID/Cushing’s, a laminitis-prone horse, or a metabolically healthy high performance athlete, this episode will help you make informed, smarter decisions around NSC. 📱 If you’d like help applying this to your horse, download the MyHappy.Horse app on the Apple App Store and start building a diet you can feel confident about. https://apps.apple.com/au/app/myhappy-horse/id6633422324 💖 And if this episode helped you, please share it with a horsey friend (especially the one currently arguing about pasture sugar on Facebook 😅)

A horse that won’t eat isn’t being “fussy”… it’s a red flag. In this episode of the Happy Horse Nutrition Podcast, Dr Nerida, PhD equine nutritionist and founder of the MyHappy.Horse app, breaks down the most common nutrition-related reasons horses go off their feed, what they look like in real life, and what actually helps.Nerida covers hindgut disturbance (including hindgut acidosis) and the appetite knock-on effects, including the destruction of  vitamin B1, why some horses go off grain but still eat hay, and how faecal/manure pH can be a handy monitoring tool (with the key low-pH threshold to watch).You’ll also hear how gastric ulcers can affect appetite (and why it’s not always obvious), plus the salt trap: too much salt can make feeds unpalatable (and may worsen discomfort in ulcer-prone horses), while too little sodium, especially after watery diarrhoea or heavy sweating, can switch appetite off entirely.And don’t miss the quick but important one: DON mycotoxin (“vomitoxin”). If a new batch of feed is eaten for a few days, then suddenly refused, it may be the feed, not your horse, and testing can help confirm it.You’ll also hear the story of Breeze, Nerida’s very old mare, and the tiny, cheap change that brought her appetite back and genuinely saved her life. Download the MyHappy.Horse app: https://apps.apple.com/app/myhappy-horse/id6633422324 Learn more: https://www.myhappy.horseAnd, if you know someone with a horse that isn’t eating well, please share this episode!

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida tackles a pasture risk that catches many good horse owners out: high-oxalate warm-season grasses that can block calcium absorption, slowly weaken bone, and set horses up for nutritional secondary hyperparathyroidism (Bighead disease). You’ll learn the simple physiology behind it (the “bone calcium bank” concept), why blood calcium can look normal even when bones are being depleted, and the real-world signs that are easy to misread; shifting lameness, sore or grumpy behaviour, odd gait, skull changes, loud breathing noise under work, dental issues and poor hoof quality. Nerida walks you through practical pasture ID tips for the big culprits—kikuyu, buffel, couch/bermudagrass, and the high-risk one: setaria! And explains how oxalate levels and risk change with growth stage and location (including cooler regions in summer). Finally, she outlines prevention: targeting a calcium: oxalate ratio of at least 0.5:1, keeping calcium balanced with phosphorus and magnesium, why lucerne/alfalfa helps on multiple fronts, and when it’s smarter to use a properly formulated balancer or get expert help… especially if setaria is involved.✅ Want help checking whether your horse’s diet is actually balanced for these pastures (without doing the maths)?

Your feed room decisions should always start with your grass. 🌱🐴 

Feeding horses during emergencies (bushfires, floods, storms, evacuations) can quickly become a “take what you can get” situation, but the choices you make in your makeshift feed room can determine whether your horse copes… or tips into dehydration, gastric ulcers, hindgut dysbiosis, colic, or even laminitis. In this practical episode of the Happy Horse Nutrition Podcast, PhD equine nutritionist Dr Nerida shares her approach to natural disaster horse feeding with one core rule: keep the diet as close to normal as possible.You’ll learn how to prioritise clean water (and what to do when horses won’t drink), why hay and fibre are your horse’s lifeline, and how to reduce risk when you’re forced to swap feeds or hays fast. We cover smart strategies like ingredient/forage variety, feeding little and often when hay is limited, avoiding the trap of over-using grain/hard feed, and why you should keep hay available when pasture regrows. There’s also specific guidance for horses with PPID (Cushing’s), insulin dysregulation, and laminitis, including when soaking hay might help in a tight spot.If you want a simple emergency checklist to protect hydration and gut health when your horse’s world is upside down, this one’s for you. ✅ Follow the Happy Horse Nutrition Podcast on Spotify/Apple so you don’t miss new episodes. Useful links & resources📲 MyHappy.Horse app (iOS): https://apps.apple.com/app/myhappy-horse/id6633422324🎧 Start here: Episode 1 - Feed Your Horse Like a Horse (foundation principles for gut health and safer feeding)🎧 Also helpful: Episode 24 - Ingredient Variety and Why it Matters in Horse Nutrition 🎧 For metabolic/laminitis horses: Episode 15 – All about laminitis – keeping your horse safe

Forage sits at the very heart of equine nutrition, yet for most horse owners, the numbers on a hay or pasture analysis can feel like a foreign language. In this deep-dive episode of the Happy Horse Nutrition Podcast, Dr Nerida sits down with Anthony Balzer and Kimberly Detmers from Feed Central and Local Ag for an enlightening conversation about what’s really in our forage, how much it changes, and why testing matters more than most people realise.Together, they explore how hay and pasture analysis can influence everything from basic health to performance, soundness, growth, and healthy pregnancies. You’ll hear:Why forage can make or break a horse’s health—and sometimes an entire racing stableHow hay and pasture testing actually worksThe critical mineral shifts that dictate whether a youngster grows sound joints or ends up with OCDWhy nitrate levels matter (and the way it affects laminitis, broodmare health, and athletic performance)What “safe” NSC levels look like for laminitic horsesWhy TEFF hay is not always the low-sugar safe option many believeHow ingredient and species diversity in forage protects gut health and reduces colic riskHow to dilute risk by feeding multiple, tested foragesWhat makes a “near perfect” performance horse hay—and why no single hay is perfect for every horse; andWhere to send hay and pasture for analysis in Australia or overseasWith practical examples, on-farm stories, and clear explanations, this episode makes hay and pasture numbers approachable for every horse owner—from broodmare managers to everyday riders.If you’ve ever wondered what your hay and pasture is really doing inside your horse, this episode is essential listening. Understanding forage is one of the most powerful ways to keep your horses healthy, performing well, and protected from avoidable nutrition-related issues. 📱 Download the MyHappy.Horse app:https://apps.apple.com/app/myhappy-horse/id6633422324🔬 Find out more about hay and pasture testing or submit a sample: https://www.feedcentral.com.au/how-to-submit-a-feed-sample-for-testing/🌱 Buy Aussie hay that has already been tested: https://www.localag.com.au/buy🐴 Check out the analysis services from Equi-Analytical: https://equi-analytical.comIf this episode helped you feel more confident about what’s in your hay and pasture, a quick rating or review in your podcast app really helps more horse owners find the show, and more horses get fed the way that’s best 💗

No magic ingredient, no perfect feed… just smart puzzle pieces put together in the right way to support horses and to honour the physiology of their ancient gut.Plus find out which feed ingredient(s) makes it onto the ‘avoid’ list, mainly because of their marketing claims (hello “grain-free” when you’re not actually grain free!). This episode is an easy listen, and will help you think clearly about nutrition, read labels better, and make more confident feeding decisions that your horse and their hindgut will thank you for.Wishing you a happy and safe festive season 🎄❤️Remember to Subscribe so you don’t miss what’s coming in 2026 🤍 — and if this episode helped, we’d love you to share it with a horse friend who’s feeling stuck with feeding!Racing Queensland's Off The Track Nutrition Hub (free resources): ⁠https://www.racingqueensland.com.au/animal-welfare/off-the-track/nutrition-education-hub⁠Download the MyHappy.Horse app (iOS): https://apps.apple.com/app/myhappy-horse/id6633422324Learn more about MyHappy.Horse: https://www.myhappy.horse 

When a horse presents with ulcers, colic risk, poor performance, slow healing,  unexplained weight change or a plethora of other health conditions, nutrition may be part of the story—even if it isn’t the primary cause. In this episode, Dr Nerida, PhD shares a practical, vet-friendly framework for a rapid field assessment of diet: the same fast mental checklist nutritionists run through when they first meet a case.You’ll walk away with three high-impact screening steps: (1) is there enough forage (and are there long fasting gaps that increase gut risk), (2) is grain being fed appropriately and in a digestible form (to avoid starch overflow into the hindgut); and (3) is the horse actually receiving correct supplementation—meaning a fortified feed/balancer/vitamin-mineral supplement at the proper feeding rate to cover common nutrient gaps and prevent “silent” deficiencies.✅ See all the figures and tables used in Dr Nerida’s AAEP presentation and read more about the rapid diet assessment framework https://www.myhappy.horse/rapidassess👇 Download the MyHappy.Horse app and use the Rapid Diet Assessment tool to quickly find red flags and decide when a full nutrition assessment is needed.https://apps.apple.com/app/myhappy-horse/id6633422324

Join Dr. Nerida as she tackles a listener question about feeding “marey mares” — those behaviourally expressive, sensitive, frequently moody, often brilliant mares. This solo Happy Horse Nutrition episode explores why behaviour challenges in mares are rarely caused by specific feed ingredients — and are almost always rooted in gut health, management, or pain.What You’ll Learn:• Why hindgut health is THE most important nutrition factor in mare behaviour 🐴• How the gut-brain axis influences temperament via dopamine and B-vitamin production 🧠• Why feeding hay before riding is non-negotiable for sensitive mares• The 3 things all mares need for stable mental health• How mycotoxin contamination (especially zearalenone in corn 🌽) wreaks hormonal havoc• Why pain (feet, ovaries, saddle fit) must be ruled out first before blaming the feed• The right way to test individual ingredients when sensitivities are suspected• And why your own energy might be mirroring back through your mare’s behaviour 🪞Dr. Nerida shares how her own anxious horses transformed through life changes, not supplements — and reflects on 25 years in the field, where true ingredient sensitivities are exceedingly rare (just 3 for alfalfa, 1 for soy!).🎧 Ideal for mare owners navigating grouchiness, grooming drama, or hormonally “hot” behaviour.

Join Dr. Nerida as she explores why ingredient variety is absolutely critical for your horse's health. In this episode, which comes complete with Lucky the Goat 🐐anecdotes, Dr Nerida reveals the three reasons diverse diets keep horses healthier, happier, and more resilient - and why feeding just one or two ingredients is putting your horse’s health at risk. What You'll Learn:Why horses chew bark and fences (and what it tells us about their diet)The THREE critical benefits of ingredient variety: balanced nutrients, toxin dilution, and microbiome diversityHow different forages and feed ingredients work together to meet nutrient requirementsWhy nitrate and mycotoxin testing is essential for racing stables and performance horsesThe downsides of monoculture pastures and why horses need species diversityProtein combining: how different proteins work together as "Tetris pieces"; andDr. Nerida's personal feeding program for her daughter's OTTB (with multiple forage and fiber sources) Dr. Nerida reveals that the more ingredients in your horse's diet, the better chance you have of meeting complete nutrient requirements - it's like putting together a puzzle where each ingredient fills specific gaps. She explains how ingredient diversity protects horses from toxins (like nitrate in hay or mycotoxins in moldy feed) by either allowing them to avoid problem forages or diluting toxins to safe levels. And she explains how horses with diverse microbiomes can handle stress events like competition and travel without developing colic or diarrhea, while horses on limited diets are far more vulnerable to dysbiosis.  📲 Discover and download the MyHappy.Horse app: https://www.myhappy.horse 🤍 And ask your nutrition questions 24/7 with Dr Nerida AI: https://www.myhappy.horse/nerida-ai If you enjoyed this episode, please leave us a rating and review!

In this evidence-first episode, Prof. Brian Nielsen (Michigan State University) and graduate researcher Renee Harbowy join me to unpack what we really know—and don’t—about glucosamine, chondroitin and MSM. We trace the research history (hello, cell culture studies), talk frankly about why high-quality equine trials are rare, and look at a clever, blinded field study run at an all-girls riding camp with ~80 horses on site.You’ll hear how horses were screened and balanced into supplement vs placebo groups, what was measured (stride length, flexion tests, IMU-based symmetry), and why lameness naturally fluctuates enough that you can fool yourself into thinking something works when studies are run without a control. We also touch on osteoarthritis prevalence in aging horses—the demand driver behind these products—and a cautionary detour into sheep models that shows why cross-species claims can mislead.And we finish with a detailed look at what best practice management for joint health actually looks like, including a suggestion to lunge yourself to feel how it feels on your own joints! Such a cool idea! I have to admit this conversation really opened my eyes to what we, as horse owners will be missing if we are relying on joint supplements to protect joints, versus relying on proper nutrition and management.  If you buy joint supplements, think about your horses joint health a lot, or just want your horse to be healthy and happy for a long lifetime, this conversation is a must!🧪 Renee's full research paper can be found here (and it is well worth the read, beautifully written and a brilliant piece of science!): https://pmc.ncbi.nlm.nih.gov/articles/PMC13113781/  Check out the amazing Black River Farm and Ranch (OMG I want to be a kid again so I can go to camp here 😂😍!) - https://blackriverfarmandranch.com Discover and download the MyHappy.Horse virtual nutritionist app: https://www.myhappy.horseIf you enjoyed this episode, please leave us a review!
